What is GIF?
GIF is one of the oldest image formats on the web, dating back to 1987. It is limited to 256 colours per frame, which is fine for simple graphics and memes but causes visible banding in photos. GIF supports basic on/off transparency and animation, and it opens everywhere, from old browsers to chat apps.
What is AVIF?
AVIF is the newest mainstream image format, based on the AV1 video codec. It often makes files 30–50% smaller than JPG and noticeably smaller than WEBP at the same visual quality, with support for transparency, HDR and wide colour. Modern browsers display AVIF, but many desktop apps, older phones and upload forms still cannot open it.
When should you convert GIF to AVIF?
- Hero images and banners on modern websites
- Image-heavy apps where every kilobyte counts
- Next-generation e-commerce catalogues
- Testing the best possible compression
Tips for the best AVIF results
- For websites, 75–85% quality is usually the best balance between size and sharpness.
- You can convert many GIF files at once. They are processed one after another and can be downloaded together as a ZIP.
- Keep your original GIF files until you have checked the converted AVIF images.
