About AVIF to GIF
Where AVIF files come from
AVIF images saved from websites won't post in many forums, chat apps, older email clients, and legacy software, which still expect GIF. GIF is the one format all of them accept.
What changes
- Colours are reduced to the best 256 for each picture, with fine dithering so gradients don't band. Photos look slightly grainy; logos and flat art barely change.
- Transparency becomes GIF's single clear colour. Partly see-through pixels become fully clear or fully solid, and the result says when that happened.
- An animated AVIF becomes a still GIF of its first frame.
- HDR and wide colour become standard colour (sRGB). Metadata is not copied.
Measured
Our 12-megapixel sample photo (4032 by 3024), saved as AVIF, converted in Chrome on a laptop. Phone timings are still to be measured.
| AVIF file | 768 KB |
|---|---|
| GIF file | 4.1 MB |
| Time in Chrome (laptop) | 1.4 seconds, most of it choosing the 256 colours |
In your browser
Chrome, Edge, Firefox, and Safari 16 and later read AVIF themselves. No browser saves GIF, so the GIF is written by a small library (gifenc, 4 KB), loaded only when you convert.
Limits
- GIF is limited to 256 colours, so photos lose some colour detail.
- Soft transparent edges can look jagged on dark backgrounds, because GIF can't store partly see-through pixels.
- Animated AVIF gives only the first frame; this tool makes still GIFs.
- Very large images may be reduced to about 16 megapixels on iPhones. The result says so.
Other options
- AVIF to PNG: full colour and soft transparency, if the app accepts PNG.
- AVIF to JPG: a smaller, full-colour file for photos.
- GIF to AVIF: the reverse, to shrink a GIF for the web.
Questions
Is the GIF animated?
No. Each AVIF becomes a still GIF. For an animated AVIF, that is its first frame, and the result says so.
Are my images uploaded?
No. Your files are processed on your device. We never upload them.
Why does the GIF look grainy?
GIF holds at most 256 colours. Photos have many more, so the converter picks the best 256 and mixes them in fine dots to keep gradients smooth. Up close that looks like grain. Flat graphics and logos look clean.
Does it keep transparency?
Yes, but GIF has only fully clear or fully solid pixels. Soft edges become one or the other, and the result tells you when that happened.
Why is the GIF bigger than the AVIF?
GIF compression is from 1987 and is far less efficient than AVIF. Our 768 KB sample photo became a 4.1 MB GIF.
