When to Convert
Common scenarios where this conversion is useful
Replacing static GIFs on websites
Static GIF images used on websites can be converted to AVIF for much smaller file sizes and richer color reproduction, improving page load times significantly.
Improving image quality from limited GIF palette
While you can't recover colors lost in the original GIF encoding, AVIF's superior compression preserves the existing quality in a smaller file without introducing additional artifacts.
Archiving GIF collections in modern format
Convert old GIF image collections to AVIF for better compression and future-proof storage. AVIF is the emerging standard backed by major tech companies.
Web performance optimization
Replace GIF images in your web assets with AVIF versions. Even static GIFs benefit from AVIF's dramatically better compression ratios.
