During format conversion, Calibre can perform some heuristic processing. For example detecting chapters and scenebreaks.

I've notices that a few epubs (especially from Project Gutenberg), could really do with that kind of heuristic processing. For example their chapters may not all be separated.

Is there a way I can execute the heuristic processing part of conversion without actually doing any conversion?

Use the command-line tool

[Manual]

If you use the command-line tool, you can do just this. Though you need to make sure the input filename and the output filename differ.

for example

ebook-convert myorig.epub mybetter.epub --heuristic-processing
