AVIF to PNG Converter
Turn .avif files into universal PNGs using your browser's own AVIF decoder. Nothing is uploaded.
PNG is lossless: every pixel is copied exactly, so there is no quality setting. Transparency is kept.
How this AVIF to PNG converter works
AVIF is the newest mainstream image format, derived from the AV1 video codec. It compresses photos even harder than WebP, which is why image CDNs and modern websites increasingly serve it, and why you end up with .avif files that nothing on your computer will open. This AVIF to PNG converter relies on the AVIF decoder built into your browser: the file is decoded locally, drawn onto a canvas and written out as a PNG. No upload, no server. The PNG downloads straight from the tab.
Because it uses the browser's own decoder, support depends on the browser. Chrome 85+, Edge 121+, Firefox 93+ and Safari 16+ (macOS Ventura / iOS 16) all decode AVIF. On an older browser the page shows a clear "can't decode AVIF" error rather than a broken file. Chrome is the safest choice on an old Mac.
Why convert AVIF to PNG at all
AVIF is excellent for delivery and poor for everything else. Photoshop only gained native support in 2023, Windows needs a separate extension to even show thumbnails, and most upload forms, CMS fields and office suites reject it outright. PNG is universally readable, lossless and supports transparency, which makes it the right intermediate format for editing or submitting an image, even though the file will be much larger.
Quality and file size
Nearly all AVIF files in the wild are lossy, and often aggressively so: a 1200 × 800 photo may be only 60 KB. Converting to PNG does not recover the detail the encoder discarded; it just stores the decoded pixels exactly. Expect the PNG to be 20 to 50 times bigger than the AVIF. A 60 KB AVIF becomes a PNG of around 1.5 to 2.5 MB. That is normal and is not a sign something went wrong.
AVIF can hold 10- or 12-bit color and HDR. A browser canvas works in 8-bit standard range, so HDR images will look like their SDR version in the PNG. Alpha transparency, on the other hand, carries over intact. Animated AVIF files convert as their first frame.
Privacy
The conversion runs on the canvas API inside your browser, so your file never leaves your device. You can load this page, turn off your connection and still convert. Nothing is stored once the tab closes, and the PNG has no metadata attached beyond its pixel data.
Related converters
For WebP files from the same kind of websites, use the WebP to PNG converter. If the PNG is too big to send, run it through the PNG to JPG converter and choose a quality around 85. To put several converted images into one document, the Image to PDF converter accepts AVIF directly and converts it on the way in.
Frequently asked questions
›Which browsers can convert AVIF?
Chrome 85+, Edge 121+, Firefox 93+ and Safari 16+ decode AVIF natively. On older browsers the page shows an error instead of a broken file; Chrome is the safest choice.
›Why is the PNG so much bigger than the AVIF?
AVIF compresses very aggressively; a 60 KB AVIF can be a 2 MB PNG. PNG stores every decoded pixel losslessly, so the size reflects the image dimensions, not the AVIF file size.
›Does it keep HDR or 10-bit color?
No. The browser canvas works in 8-bit standard range, so HDR AVIF images are converted to their standard-range look. Transparency is kept.
›Are my files uploaded?
No. Decoding and PNG encoding happen in your browser tab; the page works offline once loaded.
