02

WebP conversion routes

Different sources need different handling on the way to WebP.

Direct to WebP

The image converter re-encodes JPG and PNG sources as WebP in one step.

Best for most web images

From JPG specifically

The JPG to WebP tool is tuned for photo sources and quality-sensitive conversion.

Best for photo-heavy sets

Resize before converting

For oversized images, resize with the image resizer first so WebP encodes exactly what the page displays.

Best when dimensions exceed the layout

03

What WebP saves you

For the same visual quality, WebP is typically 25 to 35 percent smaller than JPG and 30 to 50 percent smaller than PNG for photos. On a page with many images, those savings add up to visibly faster loading and lower bandwidth costs.

04

Browser support and fallbacks

All modern browsers open WebP, so the format is safe for new work. For legacy clients, serve WebP with a JPG fallback in the picture element, and convert copies with the WebP to JPG tool when a recipient needs the older format.

Frequently asked questions

Is WebP supported everywhere?

All current browsers and operating systems support WebP. Very old programs do not, so for those audiences serve a JPG fallback or convert copies with the WebP to JPG tool.

How much smaller will my images be?

Expect roughly 25 to 35 percent savings over JPG and more over PNG at the same visual quality. The exact figure depends on the image content and the quality setting you choose.

Does WebP support transparency?

Yes. WebP supports an alpha channel, so PNG graphics with transparency convert cleanly and usually end up smaller than the PNG original.

08

Conversion stays on your device

The image converter encodes WebP locally in your browser. Your source images are read on your device and the results are produced there, with no upload and no stored copies.
