Why convert JPG to WebP
Website speed depends heavily on image weight. WebP compresses images more efficiently than JPG, so pages load faster and visitors use less mobile data. Google also recommends modern formats such as WebP for better performance.
The conversion is useful if you need to:
- speed up a website or online store;
- reduce bandwidth costs;
- improve Core Web Vitals;
- keep a good visual quality with a smaller file.
How it works
The browser decodes the JPG, draws it on a canvas and exports it as WebP. The file is never uploaded to the server. If the browser cannot encode WebP, the server takes over with sharp and deletes the result after download.
What to know
WebP is supported by all modern browsers, but very old software may not open it. Keep the original JPG if you need maximum compatibility, and use WebP as the web-optimised version. For images with transparency, convert PNG to WebP instead.
Questions and answers
Do all browsers support WebP?
Current versions of Chrome, Firefox, Edge and Safari support WebP. Very old browsers and some office programs may not.
Is the image uploaded to a server?
No. The conversion happens in your browser with the Canvas API, so the file stays on your device.
Will the quality change?
WebP uses efficient compression. At the default quality the difference is usually hard to see, while the file becomes smaller.
What is the size limit?
Up to 25 MB per image. For larger files, resize the image before converting.
