Any Way To Delete Titles And Page Numbers?

NVash · 01-06-2011, 11:16 PM

In many books they have the author name, title of the book and page number on each page. Is there any way to remove them using Calibre?

What format are these books? If they're PDFs and you're attempting to convert to something else, you can enable the header and footer regular expressions during conversion and then write appropriate regular expressions to remove the header and footer.

Note that you have to check the checkbox as well as fill out the regular expression. Too often I find myself writing the perfect regular expression, doing a conversion, looking at the output and wondering why it didn't work when it did during testing. It's always because I forgot to check the checkboxes.

Yes, theyre PDFs. How do I do that? What menu do I go into and how do I get there? Please forgive me, Im still kind of new to this so I really have no idea what Im doing.

It's in the conversion dialog

Select the book you want to convert
Open the conversion dialog (shortcut: c)
Make sure the Input format in the top left is PDF (this should be the case unless you have other formats attached the to book already)
Click on Structure Detection

From here you have "Remove Header" and "Remove Footer" options. They are pre-populated by default with a regular expression that probably won't work for you. For best results, you'll have to figure out the correct regular expressions on your own. This is where the test mode (the wand-looking buttons to the right of the regular expression text fields) is extremely useful. Google for a python regular expression reference and then build the expression you need to remove the headers and footers from your book. Just remember to check the checkboxes when you're done before you start the conversion. Also, it's probably a good idea to use the "preprocess input file" option as that can make building your regular expressions easier (it's not going to do it for you, but by preprocessing the contents of what you're running the expressions over should be more uniform).

you may find it easier to google pdfscissors & use that to remove all the headers & footers before adding pdf to calibre. saves having to learn regex syntax.

Dear Author wrote a how-to guide on using Calibre to remove headers and footers from PDFs. It takes some experimenting, but is worth the effort for a clean conversion.
