Convert Images to WebP

WebP files are usually much smaller than JPG or PNG at similar visual quality, which makes web pages load faster. Convert a whole folder of images at once and download them as a ZIP.

Your images are processed inside your browser and are never uploaded to our servers.

About this tool

Transparency in PNG files is kept, because WebP supports it.

How to use the Image to WebP

  1. Drop in up to 20 JPG, PNG or other images.
  2. Set the quality. 75-85 suits most website photos.
  3. Press Convert. Compare each result with the slider.
  4. Download files one by one or all together as a ZIP.

Limitations

  • Requires a browser that can create WebP files (current Chrome, Edge, Firefox and Safari can). If yours can't, you'll see a message instead of a wrong file.
  • Up to 20 images at a time, 50 MB each.
  • Animated GIFs become a single still WebP frame.

Frequently asked questions

Is WebP supported everywhere?

All current major browsers display WebP. Some older desktop software and some upload forms still don't accept it. Keep your originals.

Is WebP always smaller?

Usually, but not always. The before/after sizes are shown for every file so you can see the actual result.

Does it keep transparency?

Yes. WebP supports transparency, so PNG transparency is kept.
