• qpdfview — Tabbed document viewer. It uses Poppler for PDF support, libspectre for PS support, DjVuLibre for DjVu support, CUPS for printing support and the Qt toolkit for its interface.

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 supported by Poppler and only supported by Adobe Reader and Master PDF Editor.

Alternatively, web browsers such as Firefox or Chromium feature a built-in PDF viewer capable of filling out forms.

• jPDF Tweak — Java Swing application that can combine, split, rotate, reorder, watermark, encrypt, sign, and otherwise tweak PDF files.

• PDF Arranger — Helps merge or split pdf documents and rotate, crop and rearrange pages. It is a maintained fork of PDF-Shuffler.

• pdfCropMargins — Automatically crops the margins of PDF files.

With GraphicsMagick:

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

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

With Poppler and maintaining the layout:

$ pdftotext -layout in.pdf out.txt

See also .

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

The user password is used for encryption, the owner password to restrict operations once the document is decrypted, for more information, see Wikipedia:PDF#Encryption 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 can be 40, 128 or 256.

With Poppler to JPEG:

$ pdfimages infile.pdf -j outfileroot

With Ghostscript as a single file

$ gs -sDEVICE=pdfwrite -dNOPAUSE -dBATCH -dSAFER -dFirstPage=first -dLastPage=last -sOutputFile=outfile.pdf infile.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

With mutool as a single file:

$ mutool clean -g infile.pdf outfile.pdf first-last

PDF Imposition (e.g. to combine multiple pages to one page) 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.

With ExifTool:

$ exiftool file.pdf

With Poppler:

$ pdfinfo file.pdf

With Ghostscript one of:

$ ps2pdf -dPDFSETTINGS=/screen in.pdf out.pdf
$ gs -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/printer -sOutputFile=out.pdf in.pdf

For different settings see the documentation.

There is also , a script wrapping gs.

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

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.

Adding an image to any location in a PDF can be done

• with ImageMagick (convert), and . (Wrapper script)
• with
• with LibreOffice

Details on these and other solutions can be found on StackExchange.

can digitally sign PDF files with X.509 certificates in GUI and CLI.

Readers such as Okular and MuPDF can sign PDFs with digital signatures. This requires a PFX certificate, which can be created with an OpenSSL command:

$ openssl req -x509 -days 365 -newkey rsa:2048 -keyout cert.pem -out cert.pem
$ openssl pkcs12 -export -in cert.pem -out cert.pfx

MuPDF users can then sign PDFs with the cert.pfx using the graphical interface, or its mutool-sign tool.

Okular users must import cert.pfx into a certificate store such as the one in the default Firefox profile. With Firefox this is done through Settings > Privacy & Security > View Certificates > Your Certificates > Import and selecting cert.pfx. Afterwards Okular will offer this certificate to be used when signing PDFs.

Libreoffice can also sign PDFs.

With :

$ rewritepdf.pl -C in.pdf out.pdf

See https://superuser.com/a/1051543 for more information.

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.

You can use to:

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

There is a useful script img2djvu-git^AUR.

$ img2djvu -c1 -d600 -v1 ./out

it will create 600 DPI from all files in directory.

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

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

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

Explanation:

• with you define the paper size. For valid PAPERSIZE values, see .
• lets the created PDF be optimised for loading.
• makes the fonts look always nice.
