Why convert WEBP to AVIF?

AVIF typically shrinks WebP files another 25–35% at the same visual quality thanks to AV1 intra-frame coding. Perfect for fast hero images, image-heavy galleries, and Core Web Vitals.

How it works

Drop your WEBP file above and Morphix decodes it locally, then re-encodes it as AVIF using WebAssembly + the browser's native codecs. Nothing is ever uploaded — your files stay on your device. Batch as many files as your machine can handle.
