How to convert JPG to WebP
Drop your JPG files into the box above, or click Choose files. You can add several at once.
Adjust the quality if you like. The default is a good balance of size and detail.
Click Convert to WebP. Each file is processed on your device, usually in under a second.
Download the WebP files one by one, or all at once as a ZIP.
Why convert JPG to WebP?
WebP was designed by Google specifically for the web. At the same visual quality, a lossy WebP is usually noticeably smaller than a JPG, so pages load faster and use less data, which matters most on mobile connections.
Page speed tools such as Lighthouse and PageSpeed Insights routinely recommend modern formats like WebP for large images. Converting your photos is one of the simplest ways to act on that advice and improve Largest Contentful Paint.
Every current version of Chrome, Edge, Firefox and Safari displays WebP, so you can use the converted files directly on your site.
JPG vs WebP
Both formats use lossy compression, but WebP's method (derived from the VP8 video codec) keeps edges and smooth gradients cleaner at small file sizes. WebP can also store transparency and animation; JPG can do neither.
JPG's advantage is compatibility: every camera, printer, email client and photo editor opens it. Publish WebP on the web, and keep JPG for photos you send to people or services that might not support WebP.
| Property | JPG | WebP |
|---|---|---|
| Compression | Lossy | Lossy or lossless |
| Transparency | No | Yes, full alpha channel |
| Animation | No | Yes |
| Best for | Photos, camera images | Images on websites and in apps |
| Support | Everywhere, including very old software | All current browsers; some older desktop apps lack it |
Is it safe?
Yes. JPG to WebP runs entirely in your browser. Your files are read and converted by your own device using built-in browser technology, so they are never uploaded to a server and nobody else can see them.
You can check this yourself: open your browser's developer tools, switch to the Network tab and convert a file. No upload requests are made.
The new file is created from the image's pixels only, so EXIF metadata such as GPS location, camera model and capture time is not copied into it.
Files stay in this tab's memory only until you remove them or close the page.
Frequently Asked Questions
Will converting JPG to WebP reduce quality?
WebP is lossy like JPG, so the image is compressed again. At the default quality of 80% the difference is very hard to see while the file is usually much smaller. For maximum fidelity, raise the quality slider to 90% or higher.
How much smaller will my WebP files be?
It depends on the photo and the quality setting. Typical photos shrink by 25–35% at similar quality, and JPGs saved at very high quality can shrink by more. The result shows the exact size change for every file.
Can I convert many JPG files at once?
Yes. Drop up to 25 files, convert them in one go, and download them individually or together as a ZIP.
Does it work on iPhone and in Safari?
Yes. Safari can display WebP but can't create it with its built-in image engine, so on Safari a small WebP encoder (about 300 KB) is loaded the first time you convert. It still runs entirely on your device.
Is my photo's location data kept?
No. The WebP is built from the image pixels only, so EXIF data such as GPS coordinates, camera model and capture time is left out. Photos are rotated upright first, so they don't end up sideways.
Can I use WebP images on any website?
All current major browsers display WebP. If you must support very old browsers, serve the WebP with a JPG fallback using the HTML picture element.
