eBooks come in many different formats, and while some are easy to read anywhere (PDF, DOCX) others can be much trickier to handle outside of your regular reader (FB2, PDB). If that’s a problem, you might like to try TEBookConverter, a portable tool for Windows which converts these more awkward eBooks into something you can access just about anywhere.
The program is essentially a shell for Calibre, which immediately gives it support for 25+ common formats: djvu, docx, epub, fb2, html, mobi, pdf and more.
You get plenty of import options, with TEBookConverter able to open selected files, folders or entire folder trees, or you can just drag and drop the files you need onto its window.
Choosing a destination file format is as easy as selecting it from a list. Or, if you’re not sure what it should be, a library of device presets (20+ manufacturers are supported) will point you in the right direction.
By default TEBookConverter runs up to 8 conversions simultaneously for the best performance, but you can change this to anything from 1 to 16.
Once you’ve ready, click Start and the program passes your document details to Calibre, which then handles the conversion work.
This didn’t always run smoothly for us, with TEBookConverter displaying one or two error messages during various test conversions. These didn’t tell us anything useful, either. One suggested that the input files may no longer exist, but when we changed the output format everything ran just fine.
Still, we were able to bypass most of these problems with a little experimentation, and most of the time TEBookConverter ran our conversions without any difficulty. If you need this kind of document converter then it’s certainly worth a try.
