A practical conversion workspace
What is the PNGCut Image Converter Suite?
PNGCut’s Image Converter Suite is one browser workspace for the image jobs that normally send people through several different pages. You can bring in a phone photo saved as HEIC, a WebP downloaded from a website, an AVIF asset, a transparent PNG, an SVG logo, a Windows icon, a BMP or an animated GIF. The interface reads the real file signature, shows the format and dimensions, then offers only outputs that make technical sense for that input.
That last detail matters. A converter should not promise an output that its encoder cannot create. PNGCut does not call a JPG “lossless,” because JPG compression is lossy. It does not describe a photograph placed inside an SVG wrapper as a true vector. When vector tracing is selected, the result contains traced paths; when raster embedding is selected, the result is clearly marked as raster-embedded SVG.
The suite is useful for one quick file and for a mixed batch. A global output selector changes every compatible item, while each file keeps its own output menu. This makes it possible to turn several HEIC images into JPG, convert one PNG into a multi-size ICO, extract frames from a GIF and encode another image as Base64 without leaving the page.
Designed for real work
Image conversion features that stay understandable
One queue, many formats
Upload mixed JPG, PNG, WebP, AVIF, HEIC, SVG, ICO, BMP and GIF files. Choose a shared compatible output or set a different result for each item.
Controlled browser processing
Conversions run in a worker queue where supported, so one large batch is less likely to freeze the interface or exhaust memory.
Useful resize controls
Keep original dimensions, set a percentage, cap maximum dimensions or use custom Fit, Fill and Stretch behaviour.
Privacy-conscious by design
The tool reads and converts supported files on your device. It does not need an account, watermark or routine image upload.
Real vector tracing
For simple logos, signatures and icons, SVG tracing creates vector paths. Embedded-raster SVG is labelled honestly as a different output mode.
Batch downloads
Save each result separately, package completed files into one ZIP or export every GIF frame in a dedicated ZIP.
Supported conversions

Five clear steps
How to convert images online with PNGCut
- Add images. Drop one or more files into the upload area, browse from the device or paste a clipboard image with Ctrl+V.
- Check detection. PNGCut validates the file signature and displays the real format, dimensions, size and thumbnail. A renamed extension does not override the bytes.
- Choose output and settings. Apply one format to every compatible file or choose separately. Adjust quality, resize mode, transparency, ICO sizes, PDF pages or SVG tracing.
- Convert. Use an individual Convert button or Convert All. Progress, current work and errors are announced without hiding the rest of the queue.
- Review and download. Compare the original and output, check the new dimensions and size, then download one result or save completed items as a ZIP.
Quality, size and shape
Resize without guessing what Fit, Fill and Stretch mean
Original size keeps the decoded pixel dimensions. Percentage resize is convenient when every side should scale together. Maximum width and height reduce oversized images without enlarging smaller files. Custom dimensions unlock three placement modes: Fit shows the complete image inside the requested box, Fill covers the box and crops the excess, and Stretch forces the exact width and height even when the aspect ratio changes.
The aspect-ratio lock uses the first queued image as its reference while you edit custom dimensions. For mixed batches with different proportions, Fit is usually the safer choice. A size estimate appears before conversion, but it is intentionally labelled as an estimate. Real output size depends on pixel complexity, transparency, encoder behaviour and quality—not only on width and height.
A 90% JPG setting controls encoder compression. Resize controls the number of pixels. A high quality setting cannot restore detail that was absent from the original.
Local-first privacy
What happens to your images?
Supported conversions are designed to happen inside the browser. The page may download JavaScript or WebAssembly codecs, but the selected image itself is not intentionally sent to PNGCut’s server. Worker processing moves demanding decoding and encoding away from the main interface. A controlled queue avoids launching every large conversion at once. PNGCut does not use selected or converted files for AI training.
Cross-format images are decoded and written as new files, so EXIF metadata, camera comments and GPS coordinates are removed. The interface disables “keep metadata” instead of claiming that a browser canvas preserved data it cannot safely transfer. Auto-rotation uses the decoded orientation where browser support exists, so the visible picture is normally upright even though the new output no longer carries the original orientation tag.
Object URLs used for previews are temporary. PNGCut releases them when an item is removed, the queue is reset or the page is closed. Results are not a cloud backup. Download everything you need before leaving the tab.
Input safety
Why PNGCut checks bytes instead of trusting a filename
A file called “photo.png” is not necessarily a PNG. The converter checks magic bytes and container brands for JPG, PNG, WebP, AVIF, HEIC, GIF, BMP and ICO. SVG is parsed as XML and sanitised before it is rendered: scripts, event handlers, embedded HTML, unsafe URLs and external references are removed. Base64 is decoded only after length and character checks, then its image signature is validated.
Limits exist for a reason: 50 MB per file, 200 MB per batch, 50 queued files, 100 megapixels, 32,768 pixels per side and 300 GIF frames. Those boundaries reduce the risk of corrupted headers, decompression bombs and accidental memory exhaustion. A file can still be valid yet unsupported—for example, an unusual compressed BMP or an AVIF that the installed browser cannot decode. In that case the converter returns a useful error instead of producing an empty download.
Special outputs
GIF frames, Base64, PDF, ICO and SVG in the same tool
GIF frame extractor
GIF frames are composited according to their position and disposal instructions, so each downloaded PNG represents the complete visible frame rather than a small partial patch. The grid shows frame number, duration and total count. Download one frame or package the full sequence into a ZIP.
Image and Base64
Image to Base64 can return plain code or a complete Data URL and reports the character count. The TXT download avoids copying a very long value manually. The decoder works in the opposite direction: paste Base64, validate the decoded signature, inspect the preview and save the image.
Multiple images to one PDF
Drag the queue to set page order. Choose A4, A3, Letter, Legal, auto-fit or custom page dimensions, then set portrait or landscape orientation, margins, alignment, Fit or Fill, background colour, PDF quality and one, two or four images per page. When several queued files use PDF and you press Convert All, PNGCut creates one combined document in queue order.
PNG to ICO
Select one or several sizes from 16×16 through 256×256. PNGCut creates a standards-compatible ICO container with PNG-compressed icon entries. The source is fitted inside a square without adding a watermark.
Raster image to SVG
True vector tracing analyses shapes and colours and writes paths. It is suitable for simple logos, signatures, icons and high-contrast graphics. A detailed photograph may produce thousands of paths and a file larger than the original. Raster-embedded SVG is available as a separate, honestly labelled compatibility mode.
Function-specific guidance
A guide for every conversion inside this one suite
PNGCut keeps these conversions inside one interface, but their technical trade-offs are not identical. Search the guides below for the uploaded format or intended output. Each guide explains what the selected conversion really changes, where transparency or quality can be lost and what should be checked before a production file replaces the original.
13 of 13 guides shown
iPhone photos, HEIF, compatibility, transparency
HEIC to JPG or PNG
HEIC stores modern phone photographs efficiently, but some upload portals, older Windows applications and publishing systems still expect JPG or PNG. PNGCut first confirms a HEIF-family container, then uses the local HEIC decoder. JPG is normally the practical choice for opaque camera photographs; PNG is useful when another workflow specifically requires PNG, although it may be much larger.
Decoding a large iPhone image can require far more memory than its compressed file size. Keep the original HEIC because converting to JPG is lossy, and converting a photograph to PNG does not restore detail. Auto-orientation uses the decoded view, while the newly encoded file removes original EXIF and GPS metadata.
safe rasterisation, logo export, transparent SVG
SVG to PNG or JPG
SVG artwork must be rasterised when a platform accepts only pixels. PNG preserves transparency and sharp flat-colour edges; JPG produces an opaque result and is more appropriate when a smaller photographic-style export is acceptable. Use the rasterisation resolution setting to create enough pixels for the final display without generating an unnecessarily huge canvas.
Before rendering, PNGCut parses and sanitises SVG markup. Scripts, event handlers, embedded HTML, unsafe URLs and external references are blocked. Complex fonts or remote assets are not fetched silently, so an SVG that depends on them can look different. Review the preview and preserve the original vector file for future scaling.
AVIF decoder, modern image format, browser compatibility
AVIF to JPG or PNG
AVIF can deliver excellent compression and high visual quality, but not every editor or form accepts it. JPG creates a widely compatible opaque photograph, while PNG is the safer output for decoded transparency. The conversion is available only when the current browser can decode the AVIF bitstream; a visible unsupported-codec error is more trustworthy than a blank download.
JPG output is lossy and PNG output can grow dramatically because it stores decoded pixels with lossless compression. Set dimensions for the actual destination, compare the preview and keep the original AVIF when it remains the best web asset.
WebP compatibility, alpha channel, legacy apps
WebP to JPG or PNG
Convert WebP to JPG for older software and opaque photographic delivery. Choose PNG when transparent pixels, hard edges or a lossless intermediate matter. If a transparent WebP is sent to JPG, select white or a custom background colour because JPG cannot carry alpha.
Changing the container cannot improve the source. A WebP that was already encoded lossily remains limited by those pixels, and PNG may be larger without becoming more detailed. PNGCut shows the actual output size and preview so you can make the compatibility trade-off deliberately.
web optimisation, WebP quality, lossless WebP
JPG or PNG to WebP
WebP is useful for reducing website image weight while keeping broad modern-browser support. Photographs usually suit a lossy quality between roughly 75 and 90 as a starting point. Graphics with transparency or exact pixel requirements can use the lossless mode only where the browser encoder supports it.
JPG to WebP does not undo earlier JPG artifacts, and repeatedly converting between lossy formats can compound damage. PNG to lossy WebP can reduce bytes but no longer preserves every pixel exactly. Compare text, faces, gradients and transparent edges before replacing a production asset.
favicon, Windows icon, 16 to 256 pixels
PNG to multi-size ICO
An ICO file can contain several icon sizes so operating systems and desktop applications choose an appropriate entry. PNGCut offers 16, 24, 32, 48, 64, 128 and 256 pixel squares and packages the selected PNG-compressed entries in one standards-compatible ICO container.
Use a square source with a transparent background and generous internal spacing. Tiny sizes cannot display fine text or thin detail, so inspect 16×16 and 32×32 rather than judging only the large preview. For a website favicon, also keep the SVG or PNG source because modern browsers can use those directly.
icon extraction, largest icon entry, transparency
ICO to PNG
ICO containers may include multiple bitmap or PNG-compressed entries. PNGCut reads the directory, chooses the largest safe entry for the normal PNG conversion and decodes its transparency. The result is useful when an icon must be edited or placed in a web design.
A small 16×16 source entry cannot become a detailed 256-pixel graphic merely by exporting to PNG. Unusual legacy compression variants may not decode in every browser. Verify edges against both light and dark backgrounds before publishing.
bitmap conversion, lossless PNG, legacy images
BMP to PNG
BMP files are common in older Windows workflows and can be much larger than necessary because many variants store pixels with little compression. PNG is a natural modern replacement for compatible 24-bit and 32-bit bitmaps: it keeps exact decoded pixels and can preserve alpha while usually reducing storage.
The BMP family includes unusual bit depths, palettes and compression methods, so PNGCut validates the header and returns an error for variants the browser module cannot safely decode. Converting to PNG does not repair corrupted pixels or create transparency that was not present.
first frame, all frames, duration, ZIP
GIF to PNG and GIF Frame Extractor
Choose first-frame PNG when you need a still poster image from an animation. Choose Extract all frames when every composited frame matters. PNGCut follows frame positions and disposal instructions so the grid represents complete visible frames rather than only small changed rectangles.
Each card shows frame number and duration, and the full set can download as a ZIP. A 300-frame safety limit controls decompression and memory risk. PNG output does not preserve animation; keep the original GIF when timing and looping must remain.
Data URL, plain Base64, copy code, TXT
Image to Base64
Base64 represents binary image bytes as text for JSON, CSS, HTML or small self-contained examples. PNGCut can return plain Base64 or a complete data:image/... URL, reports the character count, copies the value and downloads it as TXT.
Base64 is normally about one-third larger than the binary source and can make pages or databases inefficient for large images. It is encoding, not encryption: anyone with the text can decode the image. Use it for small authorised assets, not as a privacy mechanism.
decode Data URL, validate signature, image preview
Base64 to Image
Paste a plain Base64 string or an image Data URL. PNGCut removes permitted whitespace, checks length and characters, decodes the bytes, validates the real image signature and shows a preview before download. The MIME label alone is not trusted.
Invalid padding, truncated data, non-image bytes and oversized values produce clear errors. Never paste secrets into an image decoder, and inspect the visible result before using a value received from an untrusted source.
A4, Letter, margins, drag reorder, page layout
Multiple Images to PDF
Queue several images and drag them into document order, or use the keyboard ordering controls. Choose A4, A3, Letter, Legal, auto-fit or custom dimensions; portrait or landscape; margins; alignment; Fit or Fill; background colour; quality; and one, two or four images per page.
The generated PDF is image-based. Text visible in a photograph does not become searchable, and transparent pixels are placed over the selected page background. Open the result and confirm order, crop, orientation and page count before submitting it.
vector tracing, logos, signatures, honest SVG
Image to SVG: traced vector or raster embedded
True vector tracing converts simplified colour regions and edges into paths. It works best for logos, signatures, icons and high-contrast graphics. Colour count, threshold, smoothing and path simplification control detail, while transparent-background handling avoids tracing empty pixels.
Photographs can create thousands of paths, very large SVG files and an illustrated rather than photographic appearance. Raster-embedded SVG is offered separately for compatibility, but it contains pixels and is never labelled fully vectorised. Inspect the output at high zoom and choose the mode whose technical description matches the file.
Better results
Practical conversion tips
- Keep the original until the converted result has been opened in its destination app.
- Use PNG for transparency, screenshots, diagrams and sharp UI assets; use JPG for photographs without transparency.
- Try WebP quality between 75% and 90% for a useful web-size starting point, then judge the image rather than the number.
- For vector tracing, crop empty space first and choose fewer colours for a cleaner logo result.
- Split very large mobile batches into smaller groups if the browser begins reloading tabs or the device becomes warm.
- Use progressive JPG for large editorial photographs and lossless WebP for graphics where exact pixel preservation matters.
Common questions

20 questions found
Is this image converter free?
Yes. PNGCut’s Image Converter Suite is free to use, does not require an account and does not add a watermark. Normal internet data is used to load the website and any browser codec required for the selected conversion.
Are images uploaded to the server?
The suite is designed to process supported conversions inside your browser. Images are decoded, resized and encoded on your device. PNGCut does not intentionally upload those files to its server. If a future conversion ever requires server processing, the interface must ask before an upload begins.
Can I convert multiple images together?
Yes. Add up to 50 files with a combined size of 200 MB, choose one compatible output for the batch or set formats individually, and use Convert All. PNGCut processes the queue in a controlled order to reduce memory pressure.
Can I convert HEIC to JPG?
Yes. HEIC to JPG and HEIC to PNG run locally through the browser HEIC decoder. HEIC decoding can use more memory than a normal JPG conversion, especially for large iPhone photographs.
Can I extract GIF frames?
Yes. Select Extract all GIF frames to view every decoded frame with its number and duration. You can download one PNG frame or save all frames in a ZIP. The safety limit is 300 frames per GIF.
Can I remove metadata?
Yes. Cross-format outputs are redrawn and encoded as new files, which removes EXIF metadata, comments and GPS coordinates. PNGCut does not pretend to preserve metadata when browser encoders cannot safely carry it into another format.
Can I convert images to PDF?
Yes. Add several images, drag them into the required order and choose PDF. You can set A4, A3, Letter, Legal, auto-fit or custom pages; portrait or landscape; margins; alignment; fit or fill; background colour; quality; and one, two or four images per page.
Can I convert Base64 to an image?
Yes. The Base64 decoder accepts plain Base64 or an image Data URL. It validates the decoded file signature before showing a preview and download button. Invalid text or unsupported image bytes produce a clear error.
Does the converter add a watermark?
No. PNGCut does not place a watermark, logo or attribution on converted images, extracted GIF frames, icons or PDFs.
Are converted files automatically deleted?
Converted files exist temporarily in the browser tab and are released when you remove an item, reset the tool, close the tab or navigate away. Download important results before leaving the page.
Which browsers support AVIF and WebP conversion?
Current Chromium, Firefox and Safari releases generally decode WebP and AVIF, but exact codec support depends on the browser and operating system. PNGCut tests whether the image can actually be decoded and returns an honest error when the installed browser lacks support.
Can I create a multi-size ICO file?
Yes. Choose one or more entries from 16×16, 24×24, 32×32, 48×48, 64×64, 128×128 and 256×256. PNGCut fits the source into square canvases and packages the selected PNG-compressed entries in one ICO container.
Does Image to SVG create real vectors?
True tracing mode creates SVG paths and is most useful for simple logos, signatures and icons. Raster-embedded mode places the original pixels inside an SVG wrapper and is labelled clearly; it is not presented as fully vectorised artwork.
What happens to transparent pixels when I choose JPG?
JPG cannot store an alpha channel. Choose white or a custom replacement colour before conversion. Use PNG or a transparent WebP mode when the alpha channel must remain.
Can PNGCut make a progressive JPG or lossless WebP?
The settings expose progressive JPG and WebP lossless modes only where the active browser encoder can produce the requested output. PNGCut does not call normal lossy WebP or JPG conversion lossless.
What do Fit, Fill and Stretch do?
Fit shows the complete image inside the requested rectangle, Fill covers the rectangle and crops overflow, and Stretch forces the exact width and height even if proportions change. Fit is usually safest for mixed batches.
Why was my corrupted or renamed file rejected?
The suite validates magic bytes, container brands and decoded dimensions rather than trusting the filename extension. A file renamed from another format, damaged during transfer or encoded with an unsupported variant is rejected instead of producing an unsafe or empty result.
Can I cancel and retry a conversion?
Yes. Queue work can be cancelled, and failed items expose Retry. A useful error remains attached to the file so you can change output settings, reduce dimensions or remove a damaged item without resetting the entire batch.
Why can a large image use much more memory than its file size?
Compressed files expand into raw pixels during decoding. A 10,000×10,000 RGBA image can require about 400 MB for one pixel buffer before temporary canvases and output bytes are counted, so dimension and megapixel limits protect the tab.
Can I download all converted files together?
Yes. After compatible items complete, Download All as ZIP packages the generated files locally. Individual download buttons remain available, and GIF frame extraction has its own all-frames ZIP.
