WebP Converter

Convert images to WebP to make your website faster — or turn WebP files back into JPG or PNG when an app doesn't support them.

Free to useNo sign-upProcessed locally

WebP is a modern image format that produces smaller files than JPG and PNG at similar quality, and it supports transparency. It's widely recommended for websites. However, some older programs and upload forms still can't open WebP, so converting back is just as useful.

The RIZONI TOOLS WebP Converter works both ways, handles batches, and runs entirely in your browser.

Why use WebP on your website?

WebP files are typically 25–35% smaller than JPGs of similar visual quality, and lossless WebP is usually smaller than PNG. Smaller images improve loading speed, particularly the Largest Contentful Paint metric that Google uses as part of Core Web Vitals.

All current major browsers display WebP. If you need to support very old browsers, serve a JPG fallback using the HTML picture element.

Creating WebP in your browser

This tool creates WebP files using your browser's built-in encoder. Chrome, Edge and Firefox support this. If your browser can't create WebP, you'll see a message and can switch browser or choose JPG instead.

Frequently asked questions

Is WebP better than JPG?

For websites, usually yes: WebP gives smaller files at similar quality and supports transparency. For sharing with people who use older software, JPG is more compatible.

How do I open a WebP image?

Modern browsers open WebP directly. If another app can't, convert it to JPG or PNG with this tool.

Does WebP support transparency?

Yes. Converting a transparent PNG to WebP keeps the transparent areas.

Why do I get an error when converting to WebP?

Your browser may not support creating WebP images. Try a current version of Chrome, Edge or Firefox, or choose JPG.

Are my images uploaded?

No. Conversion runs locally in your browser.
