Convert PNG to AVIF
We turn PNG into AVIF right in your browser — the file never goes to a server.
What you will lose
Nothing important: the target format does everything the source does.
How they differ

PNG
Good at
- Lossless: pixels stay exactly as they were
- Full transparency, including soft semi-transparent edges
- Opens everywhere without exception — the format is nearly thirty years old
Awkward about
- Photos weigh several times more than in JPEG or WebP
- No animation: APNG support is far from universal
Use it when
- Screenshots, diagrams, logos — anything with sharp edges and text
- When you need transparency
- When the image will be edited further
AVIF
Good at
- Compresses tighter than WebP — usually another 20–30 %
- Handles 10 bits per channel and high dynamic range
- Transparency and animation are both there
Awkward about
- Noticeably slower to encode than the others
- Support outside browsers is still thin
- On small images it sometimes loses to WebP on size
Use it when
- Large images on a site where weight matters
- When you have a fallback for older browsers
Common questions
- Does the file get uploaded to a server?
- Yes, this pair needs the server: browsers cannot encode that format. The file and the result are deleted within a couple of hours and never shared.
- Will transparency survive?
- Yes, AVIF supports transparency, so semi-transparent edges stay as they were.
- Can I get the original quality back afterwards?
- Yes, AVIF supports lossless compression, so you can go back to the original.
- How many files, and how large?
- Up to 30 files at a time, 50 MB each. No sign-up, no watermarks.
