About WebP Image Format
Common Use Cases
- Creating WebP fallbacks for AVIF images
- Compatibility with older browsers and tools
- Image pipelines that require WebP input
AVIF offers the best compression, but some older browsers, image editors, and CDN pipelines still lack support. WebP has been around longer and has near-universal support. Converting AVIF to WebP gives you a compatibility fallback with only a modest size increase.
AVIF uses the newer AV1 codec with slightly better compression, while WebP uses the older VP8 codec with broader tool and browser support. WebP files are typically 20-30% larger than AVIF at equivalent quality.
Why Convert AVIF to WebP?
Broader compatibility
WebP has been supported since Chrome 17 (2012) and Safari 14 (2020). It works in more tools, editors, and CDN pipelines than AVIF, which is still gaining adoption.
Faster encoding
WebP encodes significantly faster than AVIF, making it better for on-the-fly image processing in server pipelines.
Reliable fallback for <picture> elements
Best practice for web images is to serve AVIF with a WebP fallback. Converting AVIF to WebP generates the fallback image for your responsive image markup.
Animation support
WebP has more mature animation support than AVIF. If you need to convert animated content, WebP is the more reliable target.
