Convert PNG to WebP without uploading

Turn PNG images into much smaller WebP files in your browser. Your files never leave your device.

How to convert PNG to WebP

  1. Drop up to 10 PNG files onto the box, or click it to choose them.
  2. Adjust the Quality slider if you want smaller files.
  3. Each file is converted to WebP straight away.
  4. Click Download next to each image.

Why convert PNG to WebP

WebP files are usually much smaller than PNG and still support transparency, so they suit logos, icons and screenshots on websites. Smaller images make pages load faster.

What to expect

This tool makes lossy WebP at the quality you choose, so the result is not identical to the PNG pixel for pixel. At 90 the difference is hard to see. Current browsers all display WebP, but some older desktop software does not, so keep the PNG as your master copy.

Need a different format? The image converter handles PNG, JPG and WebP in any direction.

Questions

Is transparency kept?

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

Is the WebP lossless?

No. It is lossy WebP at the quality you set. Raise the slider for a closer match, or lower it for smaller files.

What if my browser cannot create WebP?

A few browsers cannot save WebP. If yours is one, the page tells you instead of giving you a wrong file. A current version of Chrome, Edge or Firefox will work.

Are my images uploaded anywhere?

No. The conversion happens in your browser, so your files stay on your device.
