When to convert AVIF to WebP

AVIF is the better format technically but WebP has been around longer and has broader tooling support. There are real situations where switching from AVIF to WebP is the right call.

CMS or plugin compatibility

WordPress image plugins, Shopify themes, and many CMS platforms support WebP natively but require additional setup for AVIF.

CDN or image pipeline issues

Some CDNs and image transformation APIs still lack full AVIF support. WebP works reliably across almost every major CDN.

Design tool export

Figma, Sketch and many design tools can handle WebP more reliably than AVIF for export and asset handoff workflows.

Email marketing images

Email clients have limited format support. WebP works in Gmail and modern clients. AVIF does not.

Frequently asked questions

Why convert AVIF to WebP?

AVIF has slightly better compression than WebP but worse compatibility. Some older browsers, CDNs, CMS platforms and image processing tools do not support AVIF yet. WebP has over 97% browser support. Converting to WebP ensures your images work everywhere modern browsers are used.

Will the WebP file be larger than the original AVIF?

Usually yes. AVIF achieves better compression than WebP at equivalent visual quality. The WebP output will typically be 10 to 30% larger than the original AVIF. If file size is the priority, keep the AVIF format where it is supported.

What quality setting should I use for AVIF to WebP?

Quality 82 is the default and works well for most images. Lower to 75 to 80 for smaller file sizes when serving web images. Raise to 85 to 90 when preserving fine photographic detail is important.

Is my AVIF file uploaded anywhere?

No. Everything happens locally in your browser using WebAssembly. Your images never leave your device.

Can I convert multiple AVIF files at once?

Yes. Drop multiple AVIF files or select them from the file picker. Each converts independently. Download individually or as a ZIP archive.
