Debian 12.9
I just downloaded a 30 MiB epub file, but I can discard the images that make most of this space.
Another epub file includes unsolicited advertising with a link to a subscription. I’d like to get rid of it as well.
Is there something I can use?
Usually you write the book with a text formatter and package the results in to an epub, so IDK if it’s common to edit the epub directly.
The epub is just a zip file containing a metadata file and a bunch of simplified HTML files (one per chapter). So if you’re comfortable editing HTML, or better yet writing scripts, you can probably slap together something simple that unpacks the epub, strips those images out of the pages, and re-packages the epub.
