AVIF vs WebP: Which Next-Gen Image Format Should You Choose?
Compare AVIF and WebP, the two leading modern image formats, to decide which one is right for your website.
When it comes to optimizing your website for speed and user experience, choosing the right image format matters more than ever. The two leading next-generation image formats today are AVIF and WebP. Both are significantly better than older formats like JPG and PNG, but which one should you use in your projects?
What is WebP?
Developed by Google and released in 2010, WebP was one of the first widely adopted next-generation image formats. WebP supports both lossy and lossless compression, transparency, and animation. It quickly gained traction because it offered 25-35% smaller file sizes than JPG and PNG.
What is AVIF?
Released in 2019, AVIF is the newer format based on the AV1 video codec by the Alliance for Open Media. It improves upon WebP's compression efficiency and adds support for features like HDR and wider color gamuts.
