Description Tanja Schulte 2013-09-06 19:08:25 UTC 
I'm shocked: I've just rotated some jpg images via the buttons in the toolbar, was asked to save the rotated images when I wanted to quit, said yes - and now the files are not even half the file size they were before (3,3 MB before, 732,2 KB to 1,3 MB after saving). That really is a "no go". Saving after rotation has to be lossless - or at least I want to be asked at which compression I want to save.

Reproducible: Always

I would say this is a bug, but not really a duplicate of bug 294594. Rotating the image should only update EXIF info, not write a new image in the first place.

Also not-quite-a-duplicate of https://bugs.kde.org/show_bug.cgi?id=294594. They're not the same, but unnecessarily re-saving the image triggers 294594.

Using this as the base for other bugs reporting "rotating image changed/deleted metadata and reduced the file size instead of just changing the EXIF rotation tag".
