What is a AVIF file?
AVIF is the newest mainstream image format — the still-image form of the AV1 video codec, published in 2019 — and the most poorly supported outside a browser. PNG is its opposite: the web's lossless workhorse since 1996, carrying a full alpha channel, and readable by essentially every piece of software ever written.
That combination decides the conversion. PNG is what to choose when the transparency has to survive, when the image is going to be edited again, or when the software on the receiving end is old enough that nothing modern is safe to assume.
Why convert AVIF to PNG?
- PNG keeps the alpha channel intact, so a logo or icon stays transparent instead of being flattened onto white.
- The PNG step is lossless, so the conversion adds no further generation loss before editing — the right property if the image will be opened and saved again.
- PNG opens everywhere, including software old enough to predate WebP, let alone AVIF.
- Upload forms that name their formats almost always include PNG; almost none include AVIF.
AVIF compared with PNG
| Attribute | AVIF | PNG |
|---|---|---|
| Compression | AV1 intra-frame, lossy or lossless — the strongest compressor in mainstream use | DEFLATE, lossless — modest on graphics, very large on photographs |
| Support | Chrome 85 (2020), Firefox 93 (2021), Safari 16.4 (2023); still patchy in desktop software | Everything since 1996 |
| Transparency | Yes — full alpha channel | Yes — full alpha channel, preserved by this conversion |
| Metadata | EXIF and XMP (stripped here by default) | Optional text chunks; this tool writes none |
| Typical size | ≈100 KB for a 1200×800 photograph | ≈1.5 MB for the same photograph — PNG is not a photo format |
What actually changes
The PNG side of this conversion is lossless, but that does not make the round trip lossless: whatever the AVIF encoder discarded when the file was made is gone, and writing the pixels into PNG does not bring it back. What PNG guarantees is that nothing FURTHER is lost from here.
Expect a large file if the image is a photograph. PNG compresses losslessly and photographs do not compress well losslessly — several times the size of the AVIF is normal. For photos where size matters, convert to JPG instead; PNG earns its keep on graphics, screenshots, logos and anything with transparency.
A 10-bit or HDR AVIF is written as standard 8-bit PNG, so the extra brightness range is rendered down. An animated AVIF converts only its first frame. And as with every AVIF tool on this site, browsers that cannot decode AVIF natively get a WebAssembly decoder fetched with the page — the work still happens entirely on your device.
Frequently asked questions
Does the transparency survive the conversion?
Yes, completely. AVIF and PNG both carry a full alpha channel, and the pixels move across unchanged — partial transparency included. This is the conversion to use for logos, stickers and icons saved from the web.
Why is the PNG so much larger than the AVIF?
Because PNG is lossless and the strongest lossless compression cannot compete with lossy AVIF on a photograph. Several times larger is normal. If the image is a photo and the size matters, convert to JPG instead — PNG is the right answer for graphics, screenshots and transparency, not for holiday pictures.
Is this conversion lossless?
The PNG step is — nothing further is discarded from the pixels the AVIF contains. But most AVIFs were saved lossily in the first place, and what their encoder threw away at that point is not recoverable. Lossless from here on is the honest description.
My browser cannot display AVIF files. Will this still work?
Yes. Where native AVIF decoding is missing — Safari before 16.4, for instance — a WebAssembly decoder is fetched with the page and does the work on your device instead. Nothing is uploaded either way.
Nothing is uploaded — and you can check
Conversion happens on your own device, inside this browser tab. There is no server to receive your files, which is a stronger guarantee than a promise not to look at them. Open your browser's developer tools, switch to the Network tab, and convert something: you will see no request carrying your image. The page keeps working with your network disconnected.
