Hello,

I am trying to convert an epub to mobi using Calibre but the resulting file becomes four times larger. The input file is 700k whereas the mobi file is 3.1 MB. I thought this was bizarre and unpacked the mobi file using Mobipocket Unpacker script. The images in the resulting folder were all converted to jpegs and were a lot larger, because originally I was using optimized gifs. Since I have around 100 images in my book this becomes a problem.

So, I wonder if there is a way to tell Calibre not to touch images when converting from epub to mobi. I know Kindle supports gifs, so it is not a problem. I try to keep the file size as low as possible, because of the Amazon's additional delivery charges.

Any help is greatly appreciated. Thanks!
