Good to know

The WebP to AVIF converter converts up to 20 WebP images at once directly in your browser via canvas into AVIF, with a quality slider and a default of 82. Since both WebP and AVIF support an alpha channel, existing transparency is preserved during conversion.

Typical searches include convert WebP to AVIF, compress WebP further, and modern image formats. Multiple results can be downloaded together as a ZIP, with a visible size comparison per file. Since the source can already be lossily compressed WebP, repeated lossy conversion between formats should be avoided to prevent visible detail loss.

Typical use cases

Migrate an existing WebP library to AVIF

Convert existing WebP images to AVIF when a website or app is moving to the even smaller AVIF format.

Batch-compress transparent WebP graphics

Process multiple transparent WebP graphics at once while keeping transparency in the AVIF result.

Tips for better results

Avoid double lossy compression

If the WebP was already lossily compressed, another lossy conversion leads to further, cumulative detail loss.

Check transparency after conversion

Check the AVIF result for transparent graphics, especially at semi-transparent edges.
