ABOUT THIS TOOL

Convert png to webp online

Turn PNG screenshots, illustrations, and graphics into WebP files for websites and content systems. Adjust quality to balance appearance and file size, then inspect each result.

WebP can preserve transparent backgrounds. Some images, especially simple flat graphics, may not shrink much. The before and after sizes show the actual result.

When to use it

  • Prepare PNG assets for a website or blog.
  • Convert a folder of screenshots before publishing.
  • Keep a transparent background while reducing file size.

How it works

  1. Add your png images.
  2. Adjust the options and choose Convert.
  3. Check the results, then download one file or the full batch.
Files are processed in your browser. Nothing is sent to our server.

Frequently asked questions

Does WebP support transparency?

Yes. This tool keeps transparent pixels when your browser can export WebP.

What quality should I choose?

Start around 80 and check the preview and output size. Text-heavy screenshots often need a higher setting.

Will WebP always be smaller than PNG?

No. The result depends on the source image and quality setting; the tool shows the actual output size.
