I've tried to do lossy compression of epubs with some lines of bash scripts; i.e. removing the images and fonts that were not needed. Many epubs could be downsized to a third of their size, but then I found a book that needed the supplied fonts and gave up. When doing lossy compressions can not have those kind of bugs.
What I also found was that many of the images in the epubs were already unuseable and nothing like their counter parts in phsyical books.
- solarmist 4y agoI don’t understand this. Are they epubs of comics or something? Epubs are already compressed (zip).
- robonerd 4y agoIt's not terribly uncommon to find an epub with several megabytes of cover art and a few hundred kilobytes of text.

- kristofferR 4y agoGood compression of lots of epub files can likely be way more efficient, as deduplication/compression algorithms can be run on lots of books at the same time. Especially so with a good dictionary.
