pdfScale 2
Bash Script to scale and/or resize PDFs from the command line.
Uses ghostscript (gs) to create a scaled and/or resized version of the pdf input.
In scaling mode, the PDF paper size does not change, just the elements are scaled.
In resize mode, the PDF paper will be changed and fit-to-page will be applied.
In mixed mode, the PDF will first be resized then scaled with two Ghostscript calls.
A temporary file is used in mixed mode, at the target location.

This also shows a very special case of a PDF file that has no /MediaBox defined. It is a dumb container of n-up binary PDF pages.
Ggrepfails, thenPDFInfofails (not installed), thenImageMagickfails (not installed), then- The Ghostscript PS script does the job
This was on CygWin64 @ Windows11 x64, MacOS would try mdls as well.

Scaling Mode:
- The default mode of operation is scaling mode with fixed paper
size and scaling pre-set to 0.95
- By not using the resize mode you are using scaling mode
- Flip-Detection and Auto-Rotation are disabled in Scaling mode,
you can use '-r source -s <scale>' to override.
- Ghostscript placement is from bottom-left position. This means that
a bottom-left placement has ZERO for both X and Y translations.
Resize Paper Mode:
- Disables the default scaling factor! (0.95)
- Changes the PDF Paper Size in points. Will fit-to-page
Mixed Mode:
- In mixed mode both the -s option and -r option must be specified
- The PDF will be first resized then scaled
Page Ranges:
- Please refer to the Ghostscript manual on '-sPageList' for more info and examples.
- May cause execution warnings from Ghostscript if the PDF refences pages that were
removed. The output file should still be created, but with broken internal links.
- Using a range with an inexistant page will raise a warning from Ghostscript and
may also generate blank pages.
- Single page number | ex: --range 2
- Interval | ex: --range 2-4
- List of pages | ex: --range 1,3,6
- From page to end | ex: --range 3-
- odd/even specifier | ex: --range odd
- odd/even range | ex: --range even:1-4
- mixed entries | ex: --range 1,3-5,8-
Output filename:
- Having the extension .pdf on the output file name is optional,
it will be added if not present.
- The output filename is optional. If no file name is passed
the output file will have the same name/destination of the
input file with added suffixes:
.SCALED.pdf is added to scaled files
.<PAPERSIZE>.pdf is added to resized files
.<PAPERSIZE>.SCALED.pdf is added in mixed mode

Custom Paper Size:
- Paper size can be set manually in Millimeters, Inches or Points
- Custom paper definition MUST be quoted into a single parameter
- Actual size is applied in points (mms and inches are transformed)
- Measurements: mm, mms, millimeters
pt, pts, points
in, inch, inches
Use: pdfScale.sh -r 'custom <measurement> <width> <height>'
Ex: pdfScale.sh -r 'custom mm 300 300'
Using Source Paper Size: (no-resizing)
- Wildcard 'source' is used to keep paper size the same as the input
- Useful to run Auto-Rotation without resizing
- Eg. pdfScale.sh -r source ./input.pdf
Backgrounding: (paint a background)
- Backgrounding only happens when scaling
- Use a scale of 1.0 to force mixed mode and add background while resizing
Options and Parameters Parsing:
- From v2.1.0 (long-opts) there is no need to pass file names at the end
- Anything that is not a short-option is case-insensitive
- Short-options: case-sensitive Eg. -v for Verbose, -V for Version
- Long-options: case-insensitive Eg. --SCALE and --scale are the same
- Subparameters: case-insensitive Eg. -m PdFinFo is valid
- Grouping short-options is not supported Eg. -vv, or -vs 0.9
Additional Notes:
- File and folder names with spaces should be quoted or escaped
- Using a scale bigger than 1.0 may result on cropping parts of the PDF
- For detailed paper types information, use: pdfScale.sh -p
Examples:
pdfScale.sh myPdfFile.pdf
pdfScale.sh -i '/home/My Folder/My PDF File.pdf'
pdfScale.sh myPdfFile.pdf "My Scaled Pdf"
pdfScale.sh -v -v myPdfFile.pdf

+-----------------+-------+-------+-------+-------+-------+-------+Dependencies
The script uses basename, grep, bc and gs (ghostscript).
You probably have everything installed already, except for ghostscript.
Optional dependencies are imagemagick, pdfinfo and mdls (Mac).
This app is focused in Bash, so it will probably not run in other shells.
The script will need to see the dependencies on your $PATH variable.
apt-get
sudo apt-get install ghostscript bcyum
sudo yum install ghostscript bchomebrew MacOS
brew install ghostscriptOptionals
Page Size detection is by default in Adaptive Mode.
It will try the following methods in sequence:
- Try to get
/MediaBoxwithgrep(fastest) - Failed AND MacOS ? Try
mdls - Failed ? Try
pdfinfo - Failed ? Try ImageMagick's
identify - Failed ? Try Ghostscript with a PS script
- Failed ?
Exitwith error message
The grep method will fail on PDFs without a /MediaBox.
You may install any of the optionals to be used in that case.
MacOS is fine using mdls if the metadata of the file is accurate.
The metadata is generated automatically by the OS (Spotlight)
apt-get
sudo apt-get install imagemagick pdfinfoyum
sudo yum install imagemagick pdfinfohomebrew MacOS
brew install imagemagick xpdfWindows
- The script should work fine in cygwin.
- If you are using msys/git for windows, and the script exits with a 'file not found' error,
- try running
export MSYS_NO_PATHCONV=1 - and
export MSYS2_ARG_CONV_EXCL="*" - and then running again.
Clone using git
git clone https://github.com/tavinus/pdfScale.git
cd ./pdfScale
./pdfScale.sh --versionSelf-Install
Since v2.3.0 pdfScale can install itself using the parameter --install.
By default it will install to /usr/local/bin/pdfscale
