Safari Can Convert to WebP (Yes, Including Encode)

Safari has decoded WebP for years. It still will not `canvas.toBlob('image/webp')`. Fast WebP Converter loads a libwebp WebAssembly encoder on Safari so Mac and iPhone users get real `.webp` files, locally.

Decode ≠ encode

You can view WebP in Safari. Creating WebP used to mean Chrome or cwebp. The WASM fallback closes that gap without an upload.

Why it matters

  • Designers live in Safari.
  • HEIC drop works there.
  • Telling people 'just use Chrome' is a bounce.

How to do it

  1. Open this site in Safari 16+ (preferably current).
  2. The first convert may fetch the WASM encoder, then it is cached.
  3. Drop images and convert as usual.

If encode fails

Reload once so WASM can load. Corporate proxies that block .wasm will break Safari encode; Chrome native encode may still work.

Convert a batch in your browser. Nothing is uploaded.

Frequently asked questions

Yes. The file type is image/webp from libwebp, not a PNG rename.
