MotionShine01 / Pick
Set the quality
75 percent looks almost the same as the original for most photos. A smaller largest side saves even more.
Free tool
Compress JPEG photos.
Make JPG photos and screenshots smaller to email, upload or put on a website. Each one is saved with MozJPEG, an encoder built to make smaller JPGs than the usual one at the same look. Pick the quality and a largest size, drop many at once. It runs in your browser, so nothing is uploaded.
This runs in your browser. Your pictures are never uploaded.

Questions
Good to know.
Are my pictures uploaded?
No. They are compressed in this tab with your browser, so they never leave your computer.
What is MozJPEG?
An open JPEG encoder from Mozilla. It writes standard JPG files that open everywhere, but packs them more tightly than the encoder built into browsers. In our test on two 1920 x 1080 screenshots at 75 percent, its files were about 20 percent smaller than the browser's own JPG.
What quality should I pick?
75 percent suits most photos. Screenshots with small text keep sharper edges at 85 percent or more.
Does it keep the photo's location?
No. The new file does not keep the hidden details stored in a photo, such as the camera and the place.
Can I do many at once?
Yes. Drop several together, then download them one by one or all at once in a ZIP file.
What if a picture does not get smaller?
If the result would be larger, the original is kept and the list says so.
Which browsers work?
Current Chrome, Edge, Safari and Firefox. Safari cannot save WebP files, so it saves those as PNG.
