I'm not sure if anyone in this community is doing this type of thing, but I know that there is a volunteer community of ebook editors. I've come across some books in my field that have very poor ebooks and I'd like to try editing them at least for my own use and, where appropriate, public consumption. I've tried using the built in Calibre Ebook editor which is functional but a bit of a slog. Is there dedicated software (preferably FOSS) That is really great for editing ebooks? Thanks in advance for any recommendations!

I used to use Sigil to clean up PDF conversions. It supports all the modern epub variants. It's more or less just an HTML editor.

Definitely agree with everyone else on Sigil. Perhaps you’d like to take a look at this old article: 17 Open source ePub and eBook creators

Sigil is the best by a huge amount. I use it to fix/cleanup my extremely large ebook library.

I agree. I use it all the time. Very easy to use, and can do anything you'd want. Also, it supports plugins.

If your ebooks to edit are CBZ/CBR ones, you can rename their extensions to .zip and .rar, respectively, and extract their images to edit on an image editor of your choice. If an ebook uses HTML (iirc e.g. epub internally), you can edit that too after extraction, then with a text editor of your choice.
