Shrink images to AVIF
What is AVIF?
A modern image format that is typically 30-50% smaller than JPEG and 20-30% smaller than WebP at the same visual quality.
Works everywhere
Chrome, Edge, Firefox, Safari 16 and later, and mobile browsers all display AVIF.
Faster pages
Smaller images load sooner, especially on phones, and fast pages rank and convert better.
Nothing uploaded
Everything runs in your browser with its built-in AVIF encoder. Your images never reach a server.
