💡 Pro Tips
- WebP supports both lossy and lossless. For most photos, lossy with quality 80‑90% is perfect. For graphics with sharp edges, try lossless.
- If your AVIF contains transparency, WebP preserves it (alpha channel).
- WebP decodes faster than AVIF, making it great for time‑critical applications.
- Convert in batch mode — upload multiple AVIFs and download all WebPs as a ZIP.
- We strip metadata by default, but you can keep EXIF by toggling the option.
- For animation, AVIF animated sequences become animated WebP files.
How AVIF to WebP Conversion Works
AVIF uses the AV1 codec for superior compression, while WebP uses VP8/VP9. Both are modern formats designed to outperform JPG. When you convert AVIF to WebP, our servers decode the AVIF image to raw pixels, then re‑encode using the WebP encoder. You can choose lossy or lossless mode and adjust quality.
The result is a WebP file with similar or slightly larger size than the original AVIF, but with broader browser support. All processing is server‑side and files are deleted after 10 minutes.
AVIF vs WebP: Which One to Choose?
AVIF offers better compression (20‑30% smaller than WebP) and supports HDR, but browser support is around 93%. WebP is supported by 97%+ of browsers, decodes faster, and still provides excellent compression.
For most websites, serving AVIF with a WebP fallback is ideal. Our converter helps you create the fallback version. For platforms where compatibility is paramount, WebP is the safer choice.
WebP Adoption in 2025
WebP is now supported by all major browsers, including Safari 14+ on macOS and iOS. Its combination of quality and compatibility makes it the go‑to format for web images. Converting AVIF to WebP ensures your images look great everywhere without the need for complex fallbacks.
