What is PDFCrop?
is a Perl script that crops the white margins of PDF pages and rescales
them to fit a standard size sheet of paper. It makes the printed pages
far more attractive to read!
PDFCrop is particularly useful to academics who print downloaded
journal articles and people who receive PDF documents designed for
letter size paper, but need to print the pages on A4 paper (or vice
For example, an academic may get a journal article in which the PDF
pages are only 5in. x 7in. If the he/she prints the PDF file with a
standard GNU/Linux PDF viewer on letter size paper (8.5in. x 11in),
there will be 1.75in white margins on the left and right sides and 2in.
white margins on the top and bottom. (In other words, the white margins
will consume 63 percent of the square area on the page).
International differences in paper size make PDFCrop indispensible.
Letter size paper is the most common paper size in the United States,
Canada and Mexico, while most other countries use A4 size paper.
Consequently, Americans and Italians who exchange documents with each
other may experience printing problems because letter size paper is
8.5in. x 11in, while A4 size paper is 8.27in x 11.7in.
PDFCrop solves these problems by removing the white margins and rescaling the pages to fit the user's desired paper size.
|Cool! How do get PDFCrop?
Easy. You download it from SourceForge.
How do I install PDFCrop?
PDFCrop depends on ghostscript and PDFedit.
Assuming that you have already installed these packages, then simply make sure the file "pdfcrop" is executable (i.e.: chmod 755 pdfcrop) and copy it to a directory in your $PATH. For example: /home/eric/.bin/pdfcrop Alternatively, you could (as root) copy it to /usr/local/bin/pdfcrop
In future work, I'll create a nice DEB package, so that it can be incorporated into distributions of GNU/Linux.
How do I use PDFCrop?
Open a console, cd to the directory where the PDF file is located and type: pdfcrop infile.pdf letter outfile.pdf
That command will resize and rescale the pages of "infile.pdf" so that
they fit on letter size paper. The new PDF file will, of course, be
What does PDFCrop do?
PDFCrop calls ghostscript to find the borders of the PDF's bounding
box. Next, it determines the page orientation of each page of the PDF
file. Finally, it calls PDFedit to crop and resize the pages.
PDFCrop should preserve the input file's fonts, bookmarks and hyperlinks when generating the output file.
the resulting PDF file cannot be displayed, but this is easily fixed by
filtering the file through pdfopt (a part of ghostscript).
Older versions of ghostscript print the borders
of the page bounding box twice, which will cause errors in the
calculation of the page metrics and scale factor.
Why did you create PDFCrop?
I created PDFCrop because I hate small text and ugly white margins.
Only four releases in 28 months? Why don't you spend more time working on PDFCrop?
Because I'm an evil bastard who works for peanuts at a time-consuming day job.
How can I provide suggestions? ask questions?
Easy. Place a note at the PDFCrop forums.
This script sucks! I could do a much better job!
do! I would be very happy if someone improved upon my work. That's why
PDFCrop is distributed under the terms of Open Source licenses.
Maybe one day PDFCrop (or its functionality) will be incorporated into
Okular, Evince or PDFedit. Until then, you have this script.
