Convert PNG to WebP

WebP keeps transparency like PNG does, but is often far smaller — especially for screenshots and photos saved as PNG.

How it works

  1. Your browser decodes the PNG, including its transparent areas.
  2. It encodes the pixels as WebP at the quality you choose.
  3. You download the WebP file. The original is untouched.

Your image stays on your device

This tool runs entirely in your browser. The image is never uploaded, so there is nothing for us to store, see or delete.

To check, open your browser’s developer tools, switch to the Network tab and use the tool: you will not see your image being sent anywhere.

Questions

Are my images uploaded anywhere?

No. The image is read and processed by your own browser. Nothing is sent to our servers, so there is no copy of your image anywhere but your own device.

Is transparency preserved?

Yes. WebP supports an alpha channel, so transparent and semi-transparent areas are kept.

Lossy or lossless?

Lower quality settings are lossy but much smaller, which is usually fine for photos and screenshots. At 100%, Chrome and Edge produce lossless WebP; other browsers produce very high quality lossy WebP.
