Why Convert to WebP?

WebP is a modern image format from Google that delivers the same visual quality as JPG and PNG at a much smaller file size — usually 25–35% lighter. Smaller images load faster, which improves your page speed, Core Web Vitals and search rankings, and saves bandwidth. It's supported by every modern browser.

This tool converts your images using your browser's native WebP encoder, so there's no upload, no account and no limit. It's perfect for web designers, agencies and bloggers optimising images before publishing.
