File Conversion.

I have a number of files in PDF format that I wish to convert to MOBI format for reading on my Kindle, Calibre does a fairly good job but sometimes the pages do not display correctly, I Was thinking of converting to TXT files, making any amendments to the layout and then using calibre to convert the text files to MOBI.
I Could either use Libreoffice or Word 2007, does it make any difference which I use ?
Is there any free software (other than Calibre) that is better for converting PDF to MOBI.
Any comments on this topic would be appreciated.

Re: File Conversion.

You can't convert PDF's.
The best you can do is to use OCR software to get text.

Re: File Conversion.

Have you tried the PDF to MOBI converters available online (e.g. http://www.convertfiles.com/convert/document/PDF-to-MOBI.html) ? A Google search reveals there are many.
As you've found, document (format) conversion can be a very hit-and-miss affair however trying a variety of methods will give you a good idea as to the art of the possible which may or may not be good enough.
You say you are happy to convert via 'TXT files' - this suggests you are content for all formatting to be removed (given that such files only support human-readable ASCII). If this is the case you could just copy-and-paste all the text from the PDF into a TXT file, remove any extraneous whitespace, and then convert to MOBI using Calibre.
It's a shame that the Kindle has such poor support for native PDF documents given that in many respects they are quite a convenient format choice.

I've used Calibre and been reasonably happy with it.

Re: File Conversion.

If your PDF is a scanned document, the page size is fixed.
Since you have already bought the book once, why not get a second version for free from the Pirate Bay?

Re: File Conversion.

Even if the PDF was natively created it still appears as a fixed page size on the Kindle given its inability to reflow text.
The document may only be available in PDF i.e. not a book (it is a relatively rare format for paid books).

Re: File Conversion.

Buy a proper book.
The format has remained essentially constant for hundreds of years.

Re: File Conversion.

To convert PDF documents to text format you could try the command line utility pdftotext (part of Poppler/xpdf). Run 'pdftotext -h' to get the various options. Alternatively there are are various graphical PDF viewers that use Poppler, such as Okular and Evince, that will export a PDF to text.
As others have said if the PDF is an output from a scan then nothing will work (as the PDF is simply a wrapper around a graphic) and no ereader will make a very good job of rendering it.
