Converting two-page layout pdf into one-page layout

[Gergely]

Sometimes you find pdfs that, for sparing ink, put two pages of the document onto one pdf page. But this is not convenient to read on an ebook reader.

Is there a software or a webapp that would do the conversion to one-page layout?

IIRC, you can do this with k2pdfopt. (The author, @willus, is also an MR member.

If you have advanced technical skills, you could also try ScanTailor Advanced, however, you'll need to convert the .pdf file to images.

Additional cropping tools that can also be used for a two-page(double page) spread splitting :

pdfscissors

briss
http://briss.sourceforge.net

There are probably some pdf editors with such duble-page layout cropping/splitting command(s) incorporated therein, but we can usually use any pdf editor with a basic crop function, by cropping the left and the right sides separately and then by merging those cropped pages together thereafter, like this;

There are probably ereader/tablet pdf apps that could be used instead e.g. I remember using koreader app on my kindleDX for double-page-PDF comics, but it is pretty easy and quick to use briss, pdfscissors etc. and probably easier on the readers processor or memory thereafter.

There were also quite a few online services too and some linux(Ubuntu) tools, but I have not checked them over
