How much smaller will my images be?

It depends on the image. Photos and product shots saved as PNG often shrink by more than half, because PNG stores them without loss. Flat graphics and screenshots shrink less. The results table shows the real number for each file.

Can I check the quality before I download?

Yes. After converting, select Compare next to any file and drag the divider across the image to see the original and the WebP side by side.

Do all browsers show WebP?

Every current browser displays WebP, including Safari on iPhone. Creating WebP is different: this tool needs Chrome, Edge or Firefox to save it.

Are my images uploaded?

No. Your browser does the conversion, so the images don't reach our server.
