JPG to WebP Converter — Shrink for the Web
Browser-based JPG to WebP converter for lighter web images with quality control
Runs in your browser · nothing is uploaded
Drop JPG files here
Convert up to 50 JPG files at once to WebP, up to 50 MB each. You can also choose files or paste a copied image with Ctrl+V (⌘V on Mac). Files never leave your browser.
Conversion settings
At the same visual quality WebP is usually smaller than JPG, though some older programs cannot open it. Because the JPG is already compressed once, a quality around 90 is a safe choice.
Higher is sharper and larger. At 90 the difference is usually hard to see.
EXIF data (camera, time, GPS location) is not carried over to the converted file. The photo orientation is applied.
Why convert JPG to WebP
On blogs and online shops images make up most of the download, so they affect loading speed a great deal. At comparable quality WebP files are often smaller than JPG, so converting web images makes pages lighter, and page-speed tools recommend modern formats for that reason. The conversion runs in your browser, so photos stay on your device, and you can process up to 50 files and download a ZIP.
How to use
- Drop JPG files on the dashed area or press Choose JPG files.
- Set the WebP quality. The default is 90, and for web publishing 75 to 85 often looks nearly the same.
- To reduce dimensions too, enter a value such as 1600 or 1920 under Limit long edge.
- Save each result with its card button, or grab the whole batch with the ZIP button. Example:
cover.jpgbecomescover.webp.
How it works
- Lossy compression: the output is lossy WebP, and the quality slider (10 to 100) trades size against sharpness.
- Encoder check: if the browser cannot save WebP, a notice appears at the top of the page.
- Dimensions: unchanged by default.
- Transparency: a JPG source has no alpha channel, so the WebP is opaque too.
- Metadata: EXIF is not carried over.
Scenarios
| Situation | Setting |
|---|---|
| Blog post images | Quality 80, long edge 1600 px |
| Product detail images | Quality 85, long edge 1200 to 2000 px |
| Archiving original photos | Skip conversion, keep the JPG |
To turn WebP back into JPG use WebP to JPG, and to hit a specific size limit use the image compressor.
FAQ
How much smaller is WebP than JPG?
At a similar visual quality WebP is often the smaller format, but the ratio varies from photo to photo. Some shrink a lot and some barely change, so judge by the before and after sizes shown on each card. The same quality number in two formats does not mean the same look, so compare the results yourself.
Do all browsers and programs open WebP?
Modern browsers such as current Chrome, Edge, Firefox and Safari do. Older image editors, some document programs and some upload forms may not accept it, so check where the file will be used before converting.
The page says my browser cannot save WebP.
The tool relies on the browser's own encoder. Safari can display WebP but cannot encode it from a canvas, on the Mac as well, and on iPhone and iPad the Chrome and Firefox apps use the same engine (WebKit), so they cannot save WebP either. The page tells you as soon as it loads; open it in Chrome, Edge or Firefox on a computer or an Android phone.
Does re-compressing a JPG hurt quality?
A little. Going from JPG to WebP is another round of lossy compression, which is why the default quality is a high 90. Avoid converting repeatedly and convert once from the best original you have.
What about the location data in my photos?
The WebP does not carry EXIF such as camera model, time or GPS. The rotation is applied so the picture stays upright.
