WebP is Google's web image format with lossy and lossless modes plus transparency; files are typically 25–35% smaller than JPG. AVIF gives the smallest files of any widely supported format at the same visual quality, which makes it great for fast websites.
AVIF encoding is slower than other formats, so large images take a few extra seconds. If your WebP has transparent areas, they stay transparent in the AVIF. The AVIF is saved at quality 85, which keeps detail while cutting file size.
You can drop several WebP files at once and get a ZIP of AVIF files. Each file can be up to 20 MB; there's no daily limit and no signup, and uploads are deleted from our servers within 1 hour.
Drag WebP files onto the page or click to choose them. You can add several at once.
