Why convert WebP to AVIF?

WebP is a modern Google format offering both lossy and lossless modes, transparency, and files 25–35% smaller than JPG or PNG. AVIF is a next-generation format built on the AV1 codec, producing the smallest files of any mainstream format at a given quality.

Both WebP and AVIF support transparency, so transparent regions are carried across cleanly. Moving from WebP to AVIF usually shrinks the file significantly, often by half or more, thanks to AVIF's efficient compression — great for websites, email, and saving storage. AVIF is supported across all modern browsers and is one of the best choices for website performance and Core Web Vitals.

Pixohub converts WebP to AVIF entirely inside your browser using the HTML canvas API, so your images are never uploaded to a server. That makes conversion instant, completely private, and free — turn as many WebP files into AVIF as you like. Reach for AVIF whenever you need cutting-edge web delivery where the very smallest file size wins.

WebP vs AVIF: what to expect

WebP is best for fast-loading website images that keep transparency and quality, while AVIF shines for cutting-edge web delivery where the very smallest file size wins. Keep your original WebP if you may later need the source file, and export a AVIF copy for sharing and the web.
