Convert WebP to AVIF
Convert WebP to AVIF free in your browser: upload a .webp file above and download it as .avif in seconds. No signup, no watermarks. A little, yes — AVIF is a lossy format, so the encoder discards data it considers invisible. At typical quality settings the difference is imperceptible for photos. If you plan to edit the image further, keep a copy of the WebP original.
Upload a .webp file and download it as .avif in seconds. WebP is modern format with excellent compression and quality balance, while AVIF is next-generation format with superior compression — below you can see exactly what changes in the conversion and whether switching makes sense for your image.

Should You Convert WebP to AVIF?
Conversion changes how your image is stored, not what it shows. Switching from WebP to AVIF trades one set of strengths for another, so it helps to know which side of that trade you are on.
Good reasons to switch
- ✓Best compression ratio
- ✓HDR support
- ✓Supports transparency
- ✓You need the file in a program or platform that only accepts .avif
Better off staying with WebP
- ✗Smaller file sizes than JPEG/PNG — conversion does not remove this trade-off
- ✗Supports transparency — conversion does not remove this trade-off
- ✗Supports animation — conversion does not remove this trade-off
- ✗Nothing about your current workflow requires .avif
What Changes When You Convert
Quality
Both formats support lossy compression, so quality depends on the settings used. A high-quality AVIF export is visually indistinguishable from the WebP original for almost all content.
Transparency
Transparency is preserved when converting between these two formats.
Animation
Animation support varies by converter; most single-file conversions produce a still image from frame one.
File size
File size depends on content: AVIF files are typically around 50% smaller than JPEG at the same quality, while WebP files are typically 25-35% smaller than JPEG at the same quality.

How the Converter Works
- Upload — drop your .webp file into the tool above. It is processed temporarily and never shared.
- Convert — the file is re-encoded as .avif with sensible default quality settings.
- Download — grab the finished .avif file. Nothing is stored after processing.
