WebP convert with no upload

Most online converters send your images to a server. WebpKit decodes and re-encodes in your browser — image bytes never leave your device for conversion.

Why “no upload” matters

Screenshots, product photos, and documents can include sensitive content. A local converter keeps that off a random upload API.

How to verify

1. Open DevTools (F12) → Network.
2. Convert a WebP on WebpKit.
3. Confirm there is no image POST — only the static page scripts.

What we host

We only serve the static site and libraries. Conversion is client-side. Sample files under /samples/ are public demos, not your uploads.
