AVIF to WebP Converter
Convert AVIF images to WebP when you need broader browser support without giving up most of the size savings. WebP is supported by every modern browser, AVIF still has gaps.
Broader browser support
WebP is supported by all major browsers (Chrome, Firefox, Safari, Edge) since 2020, while AVIF still has compatibility gaps on older versions.
Small file size
WebP files are typically 25-35% smaller than JPG and 80% smaller than PNG, with quality close to AVIF in most scenarios.
Transparency supported
WebP supports alpha transparency just like AVIF, so converting from one to the other preserves all visual information.

When to convert, when to keep the original
Convert when
- Your CMS or CDN supports WebP but not AVIF

- You are building a picture element fallback chain (AVIF > WebP > JPG)
- The recipient uses Safari 14-16.3 (WebP yes, AVIF no)
Keep the original when
- Your audience is on modern browsers that all support AVIF (keep AVIF)
- You need maximum compression (AVIF is 20-30% smaller)
- You need universal legacy compatibility (use JPG instead)
Frequently Asked Questions
Why convert AVIF to WebP?
Use WebP when you need a modern format with the broadest browser support today, or when integrating with a CMS or service that does not yet accept AVIF.
Will the WebP be much larger than the AVIF?
Slightly. AVIF compresses about 20-30% better than WebP at similar quality. WebP remains very compact, so the trade-off is usually worth the compatibility gain.
Is the conversion lossy?
WebP supports both lossy and lossless compression. By default Morphix uses lossy WebP at the quality you choose, which gives the best size-quality balance.
