How to convert JPG to WebP

  1. Choose a JPG file or drag it into the box above.
  2. FormatOtter converts it to WebP instantly in your browser.
  3. Download the WebP.

WebP compresses photos more efficiently than JPG at similar visual quality, so converting your JPGs is an easy web-performance win. Conversion happens locally in your browser.

Supported formats

Input: JPG/JPEG images (.jpg, .jpeg). Output: WebP. Note: Safari cannot encode WebP in the browser — use Chrome, Edge, or Firefox for this tool.

Is this private?

Yes. FormatOtter runs entirely in your browser using the built-in canvas API. Your image is never sent to a server, never stored, and never seen by anyone — it stays on your device the whole time. You can even load this page and then disconnect from the internet; the tool keeps working.

Frequently asked questions

Will converting JPG to WebP reduce quality?

The image is re-encoded, so there is a small additional compression step. At the quality level we use, the difference is not visible for typical photos, and the file usually gets meaningfully smaller.

When should I use WebP instead of JPG?

Use WebP for images served on websites — every modern browser displays it and files are smaller. Stick with JPG when a platform or app you upload to doesn't accept WebP.
