Your files are processed entirely in your browser using built-in web technologies. They are not uploaded to our servers, and closing the page clears them from memory.

How to use the PNG to WebP

  1. Choose your PNG files (several at once is fine).
  2. Adjust quality if the option is shown.
  3. Download the WebP files individually or as a ZIP.

What does this tool do?

WebP supports transparency like PNG but compresses much better, often making graphics and screenshots a fraction of the size.

Conversion happens on your device, so it's fast and your pictures stay private.

Why use it?

  • Shrink transparent graphics for the web.
  • Keep transparency intact.
  • Faster pages with no visual change.

Frequently asked questions

Are my photos uploaded?

No. Everything happens in your browser using the Canvas API. Your images never leave your device, which is why it works even on a slow connection.
