What is AVIF?
AVIF is based on the AV1 video codec and is the most efficient widely-supported image format. It excels at both photographic content and graphics, and supports transparency, HDR and wide color gamut.
AVIF encoding is slower than WebP because it is more advanced, so please allow a few extra seconds per image. The encoder loads only when you choose AVIF output, keeping the initial page lightweight.
Frequently Asked Questions
Is AVIF supported in browsers?
AVIF is supported in all modern browsers, including Chrome, Edge, Firefox and Safari 16+.
AVIF vs WebP?
AVIF is generally 20–30% smaller at equivalent quality, but takes longer to encode.
Why does it take longer?
Advanced compression is computationally heavier. The trade is a smaller final file.
Are my images uploaded?
No, encoding is done locally in your browser.
