Convert Images to WebP — Free & Bulk
WebP is the format that makes web pages feel faster. Converting your images to WebP trims their size while keeping them sharp, and it even keeps transparency. Drop in JPG, PNG, HEIC or more — one file or a few hundred — and each comes back as a tidy WebP, all in your browser with no upload and no limit.

Every image is re-encoded as WebP locally with your browser's Canvas API, so the files stay private. Use the quality slider to balance size against detail, then download a single image or the whole batch as one ZIP — ready to drop straight onto your site.
Why convert to WebP?
WebP usually produces noticeably smaller files than JPG or PNG at the same quality, which means faster pages and less bandwidth. And compatibility is no longer a worry — every major browser now supports WebP, so it is a safe default for almost any website.
What you can convert to WebP
Bring almost any common format in — each is re-saved as WebP on the way out.
Need the opposite direction? Use WebP to JPG. To squeeze files even smaller, run them through the Bulk Image Compressor, or mix formats freely with the Image Converter.
Frequently asked questions

Will WebP open on my visitors' browsers?
Almost certainly. WebP is supported by every current major browser, so it is a safe default for the web today.
Do you upload my images?

Does WebP keep transparency?
