Pdftk (PDF Toolkit)
The PDF Toolkit allows users to merge, split, rotate, decrypt/encrypt, compress/uncompress, and repair PDFs. PDFtk Free comes with a command-line tool, PDFtk Server. So you get both the GUI and the command-line interface to PDFtk!
The SSH Open Marketplace is maintained and will be further developed by three European Research Infrastructures - DARIAH, CLARIN and CESSDA - and their national partners. It was developed as part of the "Social Sciences and Humanities Open Cloud" SSHOC project, European Union's Horizon 2020 project call H2020-INFRAEOSC-04-2018, grant agreement #823782.
