WebP vs AVIF

WebP and AVIF are both modern web formats with strong compression and alpha support. AVIF often wins on size at similar quality; WebP still has broader tooling and slightly faster encode paths in many browsers.

Quick takeaways

• Prefer AVIF when target browsers support it and size is critical
• Prefer WebP for wider compatibility with mature tooling
• Both beat classic JPG/PNG for many web assets
• Always keep a fallback format for older clients when needed
