Convert an image to WebP

Noticeably smaller than JPG and PNG at comparable quality — faster to load on your site.

  • Your file never leaves your device — the server never receives or sees it.
  • WebP is supported by every modern browser — no risk of showing visitors a blank spot.
  • Transparency is preserved — unlike JPG, WebP handles an alpha channel just fine.

How it works

  1. Choose an image

    JPG, PNG, or AVIF — drag a file in or open it with the button.

  2. Pick a quality level

    Pick the quality with the slider — see the exact file size before you download.

  3. Download the WebP

    The finished file saves straight to disk, no server queue involved.
