Mass Removal of JPEG while keeping PNG?
How to remove all JPG but keep PNG of a EPUB? Maybe there is a way to access the EBUP folder to mass delete the JPG files?
Additional Info - I am able to manually remove the JPG, I just would like to do it faster. - File is an DRM-free EPUB - I am using calibre 3.6 on OS X 10.11 El Capitan - The PNG contain useful diagramms while the JPG contain additional fotos, which I don’t need and just use a lot of space. I am already using caliber’s image compression feature. I haven’t found this specific topic in the documentation nor in previous posts, but if I have missed it please link to it. Thank you for the mobileread and Calibe communities. They add a lot of value to my life. |

Use the unpack book tool in calibre which will give you a folder on your filesystem witht he files from the epub. Use whtever tools you want to delete the jpegs, then rebuild.
