What happens to your image going from JPG to WebP
- WebP is a lossy format. The Quality slider begins at 90%, which is indistinguishable from the original for almost any photo; slide it down for a smaller file and the preview shows the new size before you save.
- Make sure the place you're uploading to takes WebP – most sites and browsers do, though some older apps and forms don't.
JPG vs WebP in brief
- JPG (or JPEG) is the photo format that works almost everywhere. Lossy compression keeps files small, but there's no transparency and each re-save throws away a little more detail.
- WebP is an image format Google designed to make websites load faster. It handles lossy and lossless compression, transparency and animation, and typically comes out 25–35% smaller than a matching JPG, although some editors, older programs and upload forms still won't take it.
Windows PC tips
- Because nothing gets installed, it works on office and school PCs where you aren't allowed to add software.

Questions & answers
Does changing JPG to WebP lower the quality?
At the 90% default you won't be able to tell. WebP is lossy, so very low settings can bring blur or blocky edges.
Can I do a whole batch of JPG files?
Yes. Add as many as you want; each is converted separately, and Download all bundles them into a single ZIP.
Do my photos get sent anywhere?
No. Your browser does the conversion with your device's own processor, so your photos stay with you. Once the page has loaded you could even switch off your internet connection.
Where do I find the converted file on my Windows PC?
Click Download. The file is saved in your Downloads folder (File Explorer › Downloads).
