Convert WEBP to AVIF — The Next Step in Compression
WEBP was a major improvement over JPG and PNG when Google introduced it, but AVIF pushes compression even further. Converting WEBP to AVIF can reduce file sizes by another 20-30% while maintaining the same visual quality. For sites already using WEBP, this is the next logical step in optimizing image delivery.

256 colors max. Best for simple graphics.
Uncompressed bitmap. Very large files.
Vector trace. Best for logos and simple graphics. Not a pixel-perfect conversion.

Lossless format — files can be large
GIF is limited to 256 colors
Best for logos, icons, and line art. Photos produce stylized results.
BMP files are uncompressed and can be very large. Consider TIFF (LZW) or PNG for lossless with smaller file sizes.
Leave empty for all pages. Multi-page PDFs produce a ZIP.

Why Convert WEBP to AVIF?
AVIF typically produces files 20-30% smaller than WEBP at the same perceptual quality. Both formats support transparency and animation, so AVIF is a drop-in upgrade. Browser support for AVIF now rivals WEBP, with Chrome, Firefox, Safari 16.4+, and Edge all supporting it natively.
How to Convert WEBP to AVIF
Upload your WEBP file by dragging it into the converter or clicking to browse. Files up to 50 MB are supported.
KoalaPic decodes the WEBP and re-encodes to AVIF using optimized AV1 compression settings. Quality defaults to 80%.
Download the smaller AVIF file. Both files are automatically deleted after 1 hour.
Quality Note
Both are modern lossy formats with similar capabilities. Converting at quality 80 produces a noticeably smaller file with virtually identical visual quality. Since both formats are lossy, there is a small generation loss, but it’s imperceptible at quality 75+.
