Convert AVIF to WebP
AVIF is the newest kid on the block — great compression, slow adoption. WebP currently covers 97% of browsers, while AVIF sits around 90% and is often disabled by default in Safari. Converting AVIF to WebP trades a small compression penalty for a significant compatibility gain, ensuring your images reach the widest possible audience.
Usage Scenarios
- Serving images to enterprise users on older browsers that lack AVIF decoding
- Providing a WebP fallback in a <picture> element alongside AVIF for progressive enhancement
- Standardising an image pipeline on WebP when not all downstream tools support AVIF
Tips
- ▸Expect a modest file size increase (10-20%) compared to the source AVIF
- ▸AVIF-to-WebP conversion is lossy; quality settings carry over approximately but not identically
- ▸Using both via <picture> is ideal — serve AVIF to capable browsers, WebP to the rest
