jpeg

I have 50,000 high resolution JPEG photos, where a couple of them might occasionally be needed, about once a year.

I wanted to zip them to save disk space, except that zipping gives no space benefit - so trying to reduce the images disk usage using winzip, winrar or 7zip was not successful.

Is there any software or algorithm similar to zip to compress image size on hard disk for storage without loosing any image information?
