AVIF to PNG
When the AVIF has transparency you cannot afford to lose.

Accepts AVIF. No size limit, no sign-up.
AVIF carries an alpha channel and JPG does not, so PNG is the correct target whenever the image has a transparent background and needs to work in software that cannot read .avif.
Choose this over AVIF to JPG when
The image is a logo, an icon, a sticker or a cut-out product photo with a transparent background. Converting such a file to JPG replaces the transparency with solid colour, which usually ruins it for the purpose it was made for.
It is also the right choice when the image is entering an editing chain. PNG is lossless, so intermediate saves do not compound compression damage the way repeated JPEG saves do.
The size increase will be large
AVIF is currently the most efficient widely available image format, and PNG is lossless. Going from one to the other is close to the worst case for file growth — an order of magnitude on photographic content is entirely normal.
If the goal is compatibility rather than transparency or losslessness, AVIF to JPG will give a far smaller file. If the goal is a smaller file that still has transparency, WebP is the better target.
Optimised, not just encoded
PNG written naively from decoded pixels is routinely several times larger than necessary. We run oxipng over every PNG we produce, which chooses better row filters and removes redundant chunks without touching a single pixel.
On a flat-colour reference image this took the output from 410 KB down to 47 KB — smaller than the source file it started from. The pixels are identical either way; only the encoding is better.
Entirely in your browser
AVIF decoding is built into your browser, so nothing needs downloading to read the file. The PNG encoder and optimiser load only when you convert.
No upload means no size limit, no queue, no watermark, no account. Verify it in DevTools while converting.
Frequently asked questions
Is the transparency kept?
Yes. PNG has a full alpha channel, so any transparent area in the AVIF is preserved exactly.
Why is the PNG so much larger?
AVIF is highly efficient lossy compression; PNG is lossless and stores every pixel. A tenfold increase on photographs is normal.
Should I use PNG or WebP?
PNG for maximum compatibility and lossless storage. WebP if you want transparency with a much smaller file and only need it to work in browsers and modern software.
Does this improve image quality?
No. AVIF is lossy, so detail discarded at encode time is gone. PNG preserves the remaining pixels exactly.
Is the file uploaded anywhere?
No. Decoding, encoding and optimisation all happen in your browser tab.
