Many thanks
Removing the images. table of contents, indices, embedded fonts, etc. can be done using any epub editor. You could convert to txt but that would leave any table of contents, indices, etc. in the ebook and you would be back to editing to remove them. Not to mention that any italic, bold, etc. text would be lost in translation.

As for the size of the file? Since epub is a zip compressed container, the epub version of a text file will be quite a bit smaller than the uncompressed text file. My quick check on 5 epubs says the text files within the epub would be about 2.3 times larger when uncompressed.

Probably the fastest way to shrink your ebook collection would be to run the Modify Epub plugin with "Remove existing cover" option selected. For most of my epubs, the cover image is over 50% of the file size.
