What is Convert AVIF to WebP?
AVIF and WebP are both modern image formats, but WebP has slightly broader browser support (97% vs 92%). Converting AVIF to WebP can improve compatibility with older Safari versions and some mobile browsers while retaining most of the file size advantage over legacy formats.
WebP also offers faster decoding than AVIF in some scenarios, which can improve perceived page load performance on slower devices. This conversion gives you the best of both worlds — AVIF's superior compression during authoring, and WebP's broader compatibility for delivery.

Common Use Cases
- Converting AVIF images for delivery to audiences with older browser versions

Key Terms Explained
- Format Compatibility
- The percentage of browser installations that natively support a given image format. WebP's 97%+ support gives it a small edge over AVIF's 92%.
- Transcoding
- Converting from one compressed format to another. Quality is preserved at the level of the source format.
Pro Tips
- Test the visual quality of AVIF→WebP output at different quality settings to find the sweet spot for your images
- Consider serving AVIF to browsers that support it and WebP as a fallback using the <picture> element
- WebP decoding is generally faster than AVIF, which can benefit users on mobile or older devices
