Because JPEG isn't meant to be saved at 100% quality. The JPEG FAQ, http://www.faqs.org/faqs/jpeg-faq/part1/section-5.html, says: Except for experimental purposes, never go above about Q 95; using Q 100 will produce a file two or three times as large as Q 95, but of hardly any better quality. Q 100 is a mathematical limit rather than a useful setting. If you see a file made with Q 100, it's a pretty sure sign that the maker didn't know what he/she was doing. Do a web search on jpeg quality "100%" and you'll find lots of detailed discussions of this. GIMP's "Show preview in image window" check box is extremely helpful, and lets you see the trade-off in quality versus size. It's too bad it's not enabled by default. ...Akkana _______________________________________________ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
