Hi there,
I'm trying to convert a couple of (similar) guitar tab books I bought from Kobo to use on my Kindle. I can import them using OBOK with no apparent issues - however, when I view them in Calibre reader the text and graphics are all over the place, e.g.:![]()
I don't have a Kobo reader so can't check there, unfortunately. But when I check the Epub on Moon Reader (Android), it shows without any images whatsoever.
Converting to AZW3 yields files that are unreadable on my Kindle.
Converting to PDF (probably preferable anyway for this content) fails in the case of one of the files:
For the other file, it produces a text that replicates the distorted EPUB file (not surprising, I suppose).
Any suggestions? Thanks heaps!
