Create WebP copies directly in the browser without sending images to a server. Choose a preset and see the final size right away.

Convert images to WebP

JPG, PNG, and WebP are processed on your device.

WebP is a copy to prepare, not a format to guess

JPG is common for photos, while PNG helps when transparency and crisp graphics matter. WebP can handle both scenarios and often create a smaller file for publishing online.

Conversion should be judged from the result: compare the copy's size and visual result. That is why the tool shows before and after without changing the source file.
