Frequently Asked Questions
Why convert AVIF to WebP?
WebP has broader compatibility than AVIF. While AVIF offers better compression, some platforms, CMS upload dialogs, email clients, and social media services still don't accept AVIF. WebP is the safer middle ground — 25–35% smaller than JPG, and supported by 97%+ of browsers.
Which is better: AVIF or WebP?
AVIF typically achieves 20–50% better compression than WebP at the same visual quality. However, WebP has broader and more consistent support — especially on older Safari versions, social platforms, and CMS tools. Use AVIF for maximum compression on modern platforms, WebP for maximum compatibility.
Does AVIF to WebP preserve transparency?
Yes. Both AVIF and WebP support full alpha transparency. Your transparent AVIF images will retain every transparent pixel when converted to WebP.
Will my WebP files be larger than the AVIF originals?
Yes. AVIF is a more efficient format. WebP files will typically be 20–50% larger than equivalent AVIF files at the same quality. You're trading compression efficiency for compatibility.
Can I convert multiple AVIF files to WebP at once?
Yes. Drop multiple AVIF files and they all convert simultaneously. A "Download all" button appears when there are two or more files.
Where is WebP supported that AVIF is not?
WebP is supported in older Safari versions (macOS 11+ vs AVIF requiring Safari 16+), many social media platforms, CMS upload tools like WordPress and Shopify, and various image hosting services that haven't yet added AVIF support.
