Choose your images and each one is converted to WebP, a web image format that is usually much smaller than JPG or PNG at similar quality — so pages load faster. Transparent PNG backgrounds stay transparent.

How to use the Image to WebP Converter

  1. Choose or drop your images (up to 30).
  2. They are converted to WebP automatically.
  3. Download the WebP files, or click Download all.

Why use WebP?

WebP is an image format developed by Google for the web. Photos saved as WebP are typically around 25–35% smaller than the same photo as JPG, and graphics are often much smaller than PNG — while still supporting transparency. Smaller images make websites load faster, which helps both visitors and search rankings.

When not to use WebP

  • For printing, or for sending to people with very old software — use JPG.
  • For official forms that ask for JPG or PNG.

Creating WebP needs a browser that can save it: Chrome, Edge and Firefox can. If your browser can't, the tool tells you instead of saving the wrong format.

Frequently asked questions

Are my images uploaded to a server?

No. Conversion happens inside your browser, so your photos never leave your device. The page keeps working even if you go offline after it loads.

Can I convert several images at once?

Yes. Select or drop up to 30 images and download them one by one or all together.

Is quality lost when converting to WebP?

WebP is saved at high quality (85%), so the difference isn’t visible in normal use while the file gets noticeably smaller.

Does it keep transparency?

Yes. Transparent areas in PNG images stay transparent in the WebP file.
