How do I convert AVIF to PNG?

Add your AVIF file to the upload area above, then press Convert. The PNG file downloads straight to your device. You do not need an account, and there is no watermark.

Are my files uploaded to a server?

No. This conversion runs entirely inside your browser using WebAssembly, so the file never leaves your device — you can even disconnect from the internet after the page loads and it will still work.

Does converting to PNG reduce quality?

No. PNG is a lossless format, so the conversion preserves exactly what is in your AVIF file. Note that it cannot recover detail that was already discarded when the AVIF was first created — a lossless container does not undo earlier compression.

How large a file can I convert?

Up to 120 MB per file for this conversion. Because the work happens in your browser, the practical limit is your device's memory — larger files work on a desktop with plenty of RAM and may fail on an older phone.

Can I convert several files at once?

Yes. Add as many as you like and press Convert All. Each file is processed independently, so one failure does not stop the rest, and you can download everything together as a ZIP.

Can I use this on my phone?

Yes. FileTools360 works in mobile browsers on iOS and Android, including choosing files straight from your camera roll. Very large videos may run out of memory on a phone — those are better converted on a laptop.

AVIF and PNG explained

AVIF stores still images using the AV1 video codec's intra-frame compression. It generally achieves the smallest files of any widely supported format, and it handles wide colour gamut and HDR, which JPEG cannot.

PNG is a lossless raster format built to replace GIF. It stores every pixel exactly as given and supports a full 8-bit alpha channel, which means genuine partial transparency rather than the single transparent colour GIF offers.

Where AVIF files come from: Performance-focused websites and modern image pipelines.
Where PNG is used: Screenshots, exported logos and UI assets, and anything designed rather than photographed.

AVIF vs PNG

The two formats solve different problems, which is why converting between them involves trade-offs rather than a straight upgrade.

AVIF compared with PNG
Property	Source	Target
Compression	Lossy or lossless	Lossless
Transparency	Yes	Yes
Animation	Yes	No
Introduced	2019	1996
Browser support	Modern browsers only. Limited desktop app support.	Universally supported.

AVIF is stronger at: The best compression of any broadly supported image format. Handles HDR and wide colour gamut. Supports transparency and animation.
PNG is stronger at: Completely lossless — re-saving never degrades the image. Full alpha transparency, including soft edges and shadows. Sharp text and hard edges stay sharp.

Why convert AVIF to PNG?

People make this switch when they run into the limits of AVIF: the file needs to be opened outside a browser, or you need fast bulk encoding. PNG is the better fit when the image has transparency, text, screenshots, logos, or you need an exact pixel-for-pixel copy.

AVIF limitations that prompt the switch: Encoding is slow compared with JPEG or WebP. Desktop application support is still thin. Very low bitrates can smear fine detail in a distinctive way.
What you give up: Much larger than JPEG or WebP for photographic content. No animation in practice (APNG exists but support is inconsistent).

Does converting AVIF to PNG reduce quality?

Both formats store the content without discarding data, so this conversion preserves it exactly. The file size may change because the two formats compress differently, but the content itself is unaffected.

Converting a JPEG to PNG does not improve its quality. It freezes the image exactly as it already is, artefacts included, in a larger file.
