Your files never leave your device. Everything runs in your browser.

How it works

  1. Add your WebP filesDrop them onto the page or choose them from your device. You can add as many as you like.
  2. Set the new sizePick a percent or type a width and height in pixels. Proportions are kept unless you turn that off.
  3. DownloadCheck the new dimensions shown for each WebP, then save them one by one or as a ZIP.

Why resize WebP images?

Serving images at the size they are displayed is one of the biggest wins for page speed. A WebP that is resized to fit its slot loads faster and uses less mobile data.

You can also switch the output to JPG or PNG if another program needs it.

A common approach is to keep two versions of each image, a large one around 1600 pixels wide for desktop screens and a smaller one around 800 pixels for phones.
