AVIF vs WebP — When to Convert AVIF to WebP
AVIF and WebP are both next-generation image formats, but they differ in browser support and platform compatibility. Understanding the difference helps you decide when to convert AVIF to WebP.
| Feature | AVIF | WebP | Best Choice |
|---|---|---|---|
| File Size | Smallest (best compression) | 25–35% smaller than JPG | AVIF for compression |
| Browser Support | ~95% modern browsers | 97%+ all browsers | WebP for compatibility |
| Safari Support | Safari 16+ only | Safari 14+ full support | WebP |
| Transparency (Alpha) | ✓ Full support | ✓ Full support | Equal |
| Older iOS Devices | iOS 16+ only | iOS 14+ full support | WebP |
| CDN / Platform Support | Growing but incomplete | Universal CDN support | WebP |
| Email Clients | Very limited support | Limited but better | Neither (use JPG) |
| Encoding Speed | Slower encoding | Fast encoding | WebP |
| HDR / Wide Color | ✓ Full support | Partial support | AVIF |
| Best For | Modern sites, max quality | Max compatibility, general use | Depends on audience |
When to convert AVIF to WebP: Convert AVIF to WebP when you need maximum browser and platform compatibility — for example, when targeting users on older iOS devices (iOS 14–15), uploading to CDNs or CMS platforms that don't yet support AVIF, or delivering images to email clients. WebP offers a near-universal 97%+ browser support rate, making it the safest next-gen format for broad audiences.

AVIF to WebP Conversion Tips — Get the Best Results
Follow these best practices when converting AVIF to WebP to get the highest quality WebP output with the best browser compatibility.
Use High Quality (90%) for Most AVIF Conversions
When converting AVIF to WebP, use 90% quality (the High preset). AVIF files are already highly compressed — using a high WebP quality setting ensures you don't lose additional quality in the AVIF to WebP conversion step. Use the Before/After slider to verify the result before downloading.
Keep Transparency When Converting AVIF Logos
Always select the Keep Alpha option when converting AVIF logos, icons, and graphics with transparent backgrounds to WebP. Both AVIF and WebP support full alpha transparency — selecting Keep Alpha ensures every transparent pixel is preserved in the output WebP file.
Serve Both AVIF and WebP with a Picture Element
Rather than replacing AVIF entirely with WebP, serve both formats using the HTML picture element. This lets browsers that support AVIF load the more compressed AVIF file, while older browsers automatically fall back to the WebP version — giving you maximum compatibility without sacrificing quality.
Always Keep Your Original AVIF Files
Never delete your original AVIF source files after converting to WebP. AVIF offers better compression than WebP — keep both versions so you can serve AVIF to browsers that support it and WebP as a fallback. Converting from WebP back to AVIF would result in quality loss.
Convert AVIF to WebP Before Uploading to Older Platforms
If you're uploading to a CMS, CDN, or e-commerce platform that doesn't yet support AVIF, always convert AVIF to WebP first. Most major platforms (WordPress, Shopify, Cloudflare) support WebP natively — upload WebP to ensure your images display correctly everywhere.
Use Lossless Mode for AVIF Graphics with Sharp Edges
For AVIF images that contain logos, icons, text-heavy graphics, or illustrations with sharp edges, use the Lossless WebP preset (100% quality) when converting AVIF to WebP. This prevents any compression artifacts that could appear around sharp edges and flat colors in the converted WebP output.
