Drop a JPG above and download a WebP. At the same visible quality the WebP is typically smaller than the JPG, which makes web pages load faster. Nothing is uploaded: the page loads the converter once, then the file is read and written by your own browser.
Why convert JPG to WEBP?
Google’s WebP format was designed for the web: its lossy mode generally beats JPG at equal quality, and it is supported by every current browser. Replacing JPGs with WebP is one of the simplest page-speed improvements.
How it works
1. Drop the JPG.
2. WebP is selected; quality defaults to 90%. 75–85% is common for web photos.
3. Download the WebP and compare the sizes shown.
JPG vs WEBP
JPG: universal, lossy, no transparency.
WebP: lossy or lossless, transparency, animation, usually smaller than JPG for the same look.
If the image must also be opened by email clients, printers or older software, keep a JPG copy.
Quality notes
The JPG is decoded and compressed again, so a small amount of loss is added; at 80–90% it is not visible. Metadata (EXIF, GPS) is not copied, which also trims a few kilobytes.
Common use cases
Website and blog images; online store product photos; reducing storage of photo collections that are only viewed in browsers.
Frequently asked questions
How much smaller will it be?＋
It depends on the photo and the quality setting; the converter shows the exact before and after sizes so you can adjust.
Do all browsers support WebP?＋
Yes, all current browsers do.
Is photo metadata kept?＋
No. EXIF data such as camera and GPS location is not written to the WebP.
Should I use AVIF instead?＋
AVIF can be smaller again but encodes much more slowly. The same converter offers AVIF if you want to compare.
