PDF forms

The PDF forms column in the above table refers to AcroForms support. If you do not need your input to be directly extractable from the PDF, you can also use the applications in #Annotation or #Graphical PDF editing to put text on top of a PDF. PDF forms can be created with LibreOffice Writer (View > Toolbars > Form Controls) and the advanced PDF editors.

The proprietary and deprecated XFA format for forms, is not fully support by Poppler[1][2] and only supported by Adobe Reader and Master PDF Editor.

Annotation

  • flpsed — A PostScript and PDF annotator, only supports text boxes.
http://flpsed.org/flpsed.html || flpsedAUR

See also List of applications/Documents#Stylus note-taking.

Graphical PDF editing

  • Scribus can import and export PDF; text is imported as polygons.[3]
  • LibreOffice Draw can import and export PDF; text is imported as text; embedded fonts are substituted.[4][5]
  • Inkscape can import a single page from a PDF and export to PDF; text is imported as cloned glyphs or text; with the latter embedded fonts are substituted.
  • Graphics editors like GIMP and krita can also import and export PDFs at the cost of rasterization.

Create a PDF from images

With GraphicsMagick:

$ gm convert 1.jpg 2.jpg 3.jpg out.pdf

Concatenate PDFs

With Ghostscript:

$ gs -dNOPAUSE -sDEVICE=pdfwrite -sOUTPUTFILE=out.pdf -dBATCH 1.pdf 2.pdf 3.pdf

With PDFtk:

$ pdftk 1.pdf 2.pdf 3.pdf cat output out.pdf

With Poppler:

$ pdfunite 1.pdf 2.pdf 3.pdf out.pdf

With QPDF:

$ qpdf --empty --pages 1.pdf 2.pdf 3.pdf -- out.pdf

Convert a PDF to text

With Poppler and maintaining the layout:

$ pdftotext -layout in.pdf out.txt

See also pdftotext(1).

Decrypt a PDF

This section lists commands to decrypt a PDF to an unencrypted file. Note that most PDF viewers also support encrypted PDFs.

With PDFtk:

$ pdftk in.pdf input_pw password output out.pdf

With Poppler to PostScript:

$ pdftops -upw password in.pdf out.ps

With QPDF:

$ qpdf --decrypt --password=password in.pdf out.pdf


Tip: Forgotten passwords might be recovered with pdfcrack, see pdfcrack(1).

Encrypt a PDF

The user password is used for encryption, the owner password to restrict operations once the document is decrypted, for more information, see Wikipedia:PDF#Security and signatures.

With PDFtk:

$ pdftk in.pdf output out.pdf user_pw password

With PoDoFo:

$ podofoencrypt -u user_password -o owner_password in.pdf out.pdf

With QPDF:

$ qpdf --encrypt user_password owner_password key_length -- in.pdf out.pdf

where key_length can be 40, 128 or 256.

Extract images from a PDF

With Poppler to JPEG:

$ pdfimages infile.pdf -j outfileroot

Extract page range from PDF

With PDFtk as a single file:

$ pdftk infile.pdf cat first-last output outfile.pdf

With Poppler as separate files:

$ pdfseparate -f first -l last infile.pdf outfileroot-%d.pdf

With QPDF as a single file:

$ qpdf --empty --pages infile.pdf first-last -- outfile.pdf

Imposing a PDF

PDF Imposition can be done with pdfjam, for example paper waste can be reduced with pdfnup and pdfbook can be used to arrange PDFs into a format suitable for book binding.

Inspecting metadata

With ExifTool:

$ exiftool file.pdf

With Poppler:

$ pdfinfo file.pdf

Optimize a PDF

With Ghostscript:

$ ps2pdf -dPDFSETTINGS=/screen in.pdf out.pdf

For different settings see the documentation.

There is also shrinkpdfAUR, a third-party wrapper script.

Rasterize a PDF

With GraphicsMagick to convert a specific page:

$ gm convert -density dpi infile.pdf[page] outfile.jpg

With Poppler to convert all pages:

$ pdftoppm -jpeg -r dpi infile.pdf outfileroot

With Poppler to convert a specific page:

$ pdftoppm -jpeg -r dpi -f page -singlefile infile.pdf outfileroot

Splitting PDF pages

With mupdf-tools to split every page vertically into two pages:

$ mutool poster -y 2 in.pdf out.pdf

Can be used to undo simple imposition.

DjVu tools

  • DjVuLibre provides many command-line tools, like ddjvu(1) for example.
  • img2djvu — Single-pass DjVu encoder based on DjVu Libre and ImageMagick
https://github.com/ashipunov/img2djvu || img2djvu-gitAUR
  • pdf2djvu — Creates DjVu files from PDF files.
https://jwilk.net/software/pdf2djvu || pdf2djvu

Convert DjVu to images

Break Djvu into separate pages:

djvmcvt -i input.djvu /path/to/out/dir output-index.djvu

Convert Djvu pages into images:

ddjvu --format=tiff page.djvu page.tiff

Convert Djvu pages into PDF:

ddjvu --format=pdf inputfile.djvu ouputfile.pdf

You can also use --page to export specific pages:

ddjvu --format=tiff --page=1-10 input.djvu output.tiff

this will convert pages from 1 to 10 into one tiff file.

Processing images

You can use scantailor to:

  • fix orientation
  • split pages
  • deskew
  • crop
  • adjust margins

Make DjVu from images

There is a useful script img2djvu-gitAUR.

img2djvu -c1 -d600 -v1 ./out

it will create 600dpi out.djvu from all files in ./out directory.

Alternatively, you can try didjvuAUR, which seems to create smaller files especially on images with well defined background.

PostScript tools

  • pstotext — Converts PostScript files to text.
http://www.cs.wisc.edu/~ghost/doc/pstotext.htm || pstotext

ps2pdf

ps2pdf is a wrapper around ghostscript to convert PostScript to PDF:

$ ps2pdf -sPAPERSIZE=a4 -dOptimize=true -dEmbedAllFonts=true YourPSFile.ps

Explanation:

  • with -sPAPERSIZE=something you define the paper size. For valid PAPERSIZE values, see [6].
  • -dOptimize=true let's the created PDF be optimised for loading
  • -dEmbedAllFonts=true makes the fonts look always nice
Note: You cannot choose the paper orientation in ps2pdf. If your input PS file is healthy, it already contains the orientation information. If you are trying to use an Encapsulated PS file, you will have problems, if it does not fit in the -sPAPERSIZE you specified, because EPS files usually do not contain paper orientation informaiton. a workaround is creating a new paper in ghostscript settings (call it e.g. "slide") and use it as -sPAPERSIZE=slide.
