About JPG to WebP conversion
If you run a blog, an online shop, or a portfolio, most of your page weight is probably JPEG photography. WebP was designed as a modern replacement and usually delivers the same perceived quality in a meaningfully smaller file, which means faster loads on mobile data and better scores in page speed tools. Converting your existing JPG library is a common step when a performance report flags "serve images in next-gen formats".
Because both formats are lossy, converting from one to the other is a re-encode: the browser decodes the JPEG into pixels and compresses them again as WebP. Start with the highest-quality originals you have rather than already-shrunk copies, and avoid going back and forth between formats repeatedly. A quality of 75–85 is typical for photos on the web.
This is also a convenient moment to fix oversized uploads. Cameras and phones produce images 4000 pixels wide or more, while most layouts display them at 1200–2000 pixels. Type a max width and the converter scales proportionally while encoding, saving a separate resize step. WebP output depends on your browser's encoder; Chrome, Edge, and Firefox support it.
How to do it
- Click the button above to open the Image tool with WebP output selected.
- Add your JPG or JPEG photos to the drop zone.
- Pick a quality between 75 and 85 for typical web photography.
- Enter a max width that matches your site's largest image slot, for example 1600.
- Run Convert images and download the WebP versions one by one.
