Convert AVIF to PNG

A lossless, transparent-capable copy of an AVIF image, made on your device.

Convert AVIF images to lossless PNG in your browser, transparency preserved. It is free, needs no account and adds no watermark, and your files are not uploaded: everything runs in your browser on your device. The size limit is your device’s memory, and phones hold less; give the page a short while after one visit to save itself for offline use, and then it works offline.

Drop AVIF files hereor click to choose files. Batches welcome.

    Your files are processed on this device and never sent to a server. Reload the page to clear everything from memory.

    Pick PNG over JPG when the AVIF has transparency, or when the image will be edited further and you do not want another lossy step. PNG is the lossless container everything can open.

    Your browser decodes the AVIF and the converter writes a PNG with the alpha channel intact. The file will be much larger than the AVIF, because AVIF is one of the most efficient lossy formats and PNG stores every pixel.

    Have another type of picture? Convert any image to PNG takes PNG, WebP, HEIC, GIF, BMP, AVIF and more.

    How it works

    1. Drop your AVIF files onto the page, or tap to pick them. Batches are fine.
    2. There are no quality settings: PNG is lossless, so the output matches the decoded image exactly.
    3. Download each PNG, or all of them as one zip.

    In your browser, not on a server

    Stayput first reads the opening bytes of each file, where every image format writes its signature, so it knows what the file really is whatever it is called. Your browser decodes JPG, PNG, WebP, GIF, BMP, AVIF and SVG itself; TIFF goes through UTIF.js, HEIC through the libheif WebAssembly decoder, and JPEG XL (or AVIF, in a browser without native support) through the Squoosh decoders, all served from this site and cached. The browser re-encodes JPG, PNG and WebP; PDF, ICO, GIF, BMP and TIFF files are written by small encoders in the page. Nothing here needs a server.

    Compared with upload-based tools: Online converters upload your image, convert it on their machine, keep it for hours and cap you at a few files a day. This does the same conversion on your device, for as many files as your device’s memory can hold, with no upload to wait for.

    Verify it yourself. Give the page a short while after one visit to save itself for offline use, then turn off Wi-Fi or switch to airplane mode and run the tool again. Or open your browser's developer tools (F12, or Cmd-Option-I on a Mac), pick the Network tab, and watch it while you convert. The panel above does the same count for you.

    Questions

    Is transparency preserved?

    Yes. Transparent areas of the AVIF come through as transparent PNG.

    Why is the PNG so big?

    AVIF compresses very aggressively; PNG does not compress lossily at all. A 100 KB AVIF can become a multi-megabyte PNG. Use AVIF to JPG when size matters and transparency does not.

    Which browsers can do this?

    Any current version of Chrome, Edge, Firefox or Safari 16 and later. Decoding happens in the browser, so an old browser without AVIF support will show an error rather than upload the file anywhere.

    Compress GIF

    Make an animated GIF small enough for Discord, Slack, email or a web page. It is compressed on this device and never uploaded.

    Compress PNG

    Shrink PNG screenshots, logos and graphics while keeping them PNGs, transparency and all. Nothing is uploaded.

    Remove EXIF Data

    See what a photo reveals, then delete it. The image data is copied unchanged and only the metadata is removed; a sideways JPG is re-encoded only if Apply orientation is on.
