Why convert WebP to AVIF?

Even smaller than WebP

AVIF is the newest mainstream web image format, built on the AV1 video codec. For the same visual quality it is typically 20% or more smaller than WebP, especially for photographic content, so converting WebP to AVIF squeezes extra bytes out of images you have already optimized. That is worth it for performance-critical pages where every kilobyte counts toward Core Web Vitals.

Check support, keep a fallback

AVIF is supported in all current versions of Chrome, Edge, Firefox, and Safari, but very old browsers may not display it, so serving a WebP or JPG fallback via the picture element is still good practice. Picovert converts WebP to AVIF in your browser with no upload. AVIF encoding is computationally heavier, so it can take a moment longer than other conversions for large images.

WebP to AVIF — FAQ

Why convert WebP to AVIF?+
AVIF usually compresses 20% or more smaller than WebP at the same quality, so it is worth it for squeezing already-optimized images even further.
Is AVIF supported everywhere?+
All current major browsers support AVIF. For very old browsers, serve a WebP or JPG fallback using the picture element.
Will quality drop?+
AVIF preserves quality very efficiently; at default settings the result looks the same while being smaller. You can raise quality or use lossless mode.
Why is conversion a little slower?+
AVIF encoding is more computationally intensive than WebP, so large images can take slightly longer to process.
Are my files uploaded?+
No. The conversion runs in your browser and your files never leave your device.
Can I batch-convert?+
Yes. Add several WebP files and convert them together, then download all at once.
