• Apply a background watermark or a foreground stamp

• Report PDF metrics, bookmarks and metadata

• Add/Update PDF bookmarks or metadata

• Attach files to PDF pages or the PDF document

• Unpack PDF attachments

• Burst a PDF document into single pages

flyer-composer can be used to prepare one- or two-sided flyers for printing on one sheet of paper.

Imagine you have designed a flyer in A6 format and want to print it using your A4 printer. Of course, you want to print four flyers on each sheet. This is where Flyer Composer steps in, creating a PDF which holds your flyer four times. If you have a second page, Flyer Composer can arrange it the same way - even if the second page is in a separate PDF file.

This package contains both the command line tool and the gui too.

The zathura-ps plugin adds PS support to zathura using libspectre.

MuPDF is a C library that implements a PDF and XPS parsing and rendering engine. It is used primarily to render pages into bitmaps, but also provides support for other operations such as searching and listing the table of contents and hyperlinks.

The library ships with a rudimentary X11 viewer, and a set of command line tools for batch rendering pdfdraw, rewriting files pdfclean, and examining the file structure pdfshow.

PDFmarks is a technique that accompanies PDF, and that is used to store metadata such as author or title, but also structural information such as bookmarks or hyperlinks.

When Ghostscript reads the main PDF generated by the TeX system with embedded PDF files and outputs the final PDF, the PDF page mode and name targets etc. are not preserved. Therefore, when you open the final PDF, it is not displayed correctly. Also, remote PDF links do not work correctly.

This program is able to extract the page mode and named targets as PDFmark from PDF. In this way, you can obtain embedded PDF files that have kept this information.

PoDoFo is a C++ library and set of command-line tools to work with the PDF file format. It can parse PDF files and load them into memory, and makes it easy to modify them and write the changes to disk. It is primarily useful for applications that wish to do lower level manipulation of PDF, such as extracting content or merging files.

fbida contains a few applications for viewing and editing images on the framebuffer.

This is the ReportLab PDF Toolkit. It allows rapid creation of rich PDF documents, and also creation of charts in a variety of bitmap and vector formats.

Impressive is a tool to display PDF files that provides visual effects such as smooth alpha-blended slide transitions. It provides additional tools such as zooming, highlighting an area of the screen, and a tool to navigate the PDF pages.

Paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file through the Pango Cairo back end.

This package provides Python bindings for the Qt5 interface of the Poppler PDF rendering library.

libHaru is a library for generating PDF files. libHaru does not support reading and editing of existing PDF files.

unpaper is a post-processing tool for scanned sheets of paper, especially for book pages that have been scanned from previously created photocopies.

Its main purpose is to make scanned book pages better readable on screen after conversion to PDF. Additionally, unpaper might be useful to enhance the quality of scanned pages before performing OCR.

The cpdf package provides a command-line tool and an OCaml library designed for manipulating PDF documents. Key Features include:

• Splitting and merging PDF files (including bookmark preservation and splitting on bookmarks).

• Encryption and decryption (supports AES 128 and AES 256).

• Page manipulation: scaling, rotation, cropping, and flipping; fitting pages to a specific size.

• Bookmark management: copying, removing, and adding bookmarks.

• Watermarking: stamping logos, page numbers, and multi-line text with transparency support.

• Text and font handling: embedding TrueType fonts, supporting Unicode UTF-8 input and output, and converting text to PDF.

• Presentation features: creating PDF-based presentations and arranging multiple pages on a single page.

• Annotation management: listing, copying, setting, and removing annotations.

• Metadata management: reading and setting document information and metadata.

• Attachment handling: adding and removing file attachments to documents or pages.

• Advanced features: thickening hairlines, blackening text, reconstructing malformed files, detecting missing fonts and low-resolution images, exporting/importing in JSON format, and building table of contents.

• Drawing: Adding graphics and text directly onto PDF files.

This package provides optional encoding files for Poppler. When present, Poppler is able to correctly render CJK and Cyrillic text.

pdfpc is a presentation viewer application which uses multi-monitor output to provide meta information to the speaker during the presentation. It is able to show a normal presentation window on one screen, while showing a more sophisticated overview on the other one providing information like a picture of the next slide, as well as the left over time till the end of the presentation. The input files processed by pdfpc are PDF documents.

The zathura-cb plugin adds comic book support to zathura using libarchive.

The zathura-pdf-poppler plugin adds PDF support to zathura by using the poppler rendering engine.

Stapler is a pure Python alternative to PDFtk, a tool for manipulating PDF documents from the command line. It supports

• cherry-picking pages and concatenating them into a new file

• splitting a PDF document into single pages each in its own file

• merging PDF documents with their pages interleaved

• displaying metadata in a PDF document

• displaying the mapping between logical and physical page numbers

img2pdf converts images to PDF via direct JPEG inclusion. That conversion is lossless: the image embedded in the PDF has the exact same color information for every pixel as the input.

PyPDF2 is a pure Python PDF library capable of:

1. extracting document information (title, author, …)

2. splitting documents page by page

3. merging documents page by page

4. cropping pages

5. merging multiple pages into a single page

6. encrypting and decrypting PDF files

By being pure Python, it should run on any Python platform without any dependencies on external libraries. It can also work entirely on StringIO objects rather than file streams, allowing for PDF manipulation in memory. It is therefore a useful tool for websites that manage or manipulate PDFs.

Pdfgrep searches in pdf files for strings matching a regular expression. Support some GNU grep options as file name output, page number output, optional case insensitivity, count occurrences, color highlights and search in multiple files.

WeasyPrint helps web developers to create PDF documents. It turns simple HTML pages into gorgeous statistical reports, invoices, tickets, etc.

From a technical point of view, WeasyPrint is a visual rendering engine for HTML and CSS that can export to PDF and PNG. It aims to support web standards for printing.

It is based on various libraries but not on a full rendering engine like WebKit or Gecko. The CSS layout engine is written in Python, designed for pagination, and meant to be easy to hack on. Weasyprint can also be used as a python library.
