Frequently asked questions
Converting GIF to AVIF is worth doing when you need what AVIF offers: the smallest files of the common formats. GIF gives you animation and very wide compatibility, but its drawback is only 256 colours, so photographs band badly.
How it works
- Add your GIF files.
- The output format is already set to AVIF.
- Adjust quality if the format supports it.
- Download the converted AVIF files.
Good to know
One thing to keep in mind: slower to encode and not supported everywhere yet. Converting does not repair damage already present in the source — if the GIF was heavily compressed, those artefacts carry across into the AVIF.
Frequently asked questions
Is converting GIF to AVIF lossless?
AVIF is a lossy format, so the conversion re-encodes and discards a little detail. At high quality settings the difference is not visible in normal viewing.
Why convert GIF to AVIF at all?
Usually for the smallest files of the common formats. If neither of those matters for your use, keeping the GIF is perfectly fine.
