Convert AVIF images to PNG straight in your browser, one at a time or all at once. No file is uploaded anywhere: your own computer does the decoding and the encoding, which is why the conversion is instant and there is no size limit.
So that software which cannot yet read AVIF can open the image. The resulting PNG will be far larger: that is the price of going back to a lossless format.
AVIF is the smallest of the four at equal quality, often half the size of a JPEG. The trade-off is that encoding it is slow and support outside the browser is still patchy. PNG, on the other hand, is a lossless format with transparency, ideal for screenshots, logos and drawings with flat areas of colour, although it is heavy with photographs, because it does not exploit the fact that the eye misses fine detail.
How to use it
- Drag the images onto the area above, or click to pick them.
- Choose the target format and, where it applies, the quality.
- Press “Process” and download the results one by one or together as a ZIP.
Frequently asked questions
- Is quality lost going from AVIF to PNG?
- No. PNG is lossless, so the result holds exactly the pixels it was handed. That said, if the source had already lost quality, that does not come back.
- What happens to transparency?
- It survives: both AVIF and PNG have an alpha channel.
- Can I convert a lot at once?
- Yes. Drop in as many files as you like: they are processed in parallel across every core your processor has, and you can download them together as a ZIP.
- Are the images sent to a server?
- No. Everything happens inside this tab. Once the page has loaded you can disconnect from the network and carry on converting.
