About the JPG to WebP Converter

Drop a JPG file above and this converter re-encodes it as WebP entirely inside your browser - no server round-trip, no queue, no watermark. You can convert up to five images at once and see the exact before-and-after file sizes, so you know precisely what you gained before you download.

WebP is the format modern websites use to make image-heavy pages feel instant: at the same visual quality it typically weighs 25-35% less than an equivalent JPG, and every current browser displays it. If you are optimizing Core Web Vitals or just tired of multi-megabyte photo attachments, converting your JPG library to WebP is the single biggest free win.

How to use it

  1. 1Drop one or more JPG images onto the upload area (up to 5 at a time).
  2. 2Drag the quality slider if you want smaller files, then click Convert.
  3. 3Compare the new file size shown next to each image, then download the WebP version.
