This is a simple program to merge PDF files. It simply merges all files with no modification.

How to use it?

Quite simple, you can specify files to merge, or merge all files under a directory.

  -o, --output       Required. Output PDF file, will automatically add .pdf extension

  -r, --recursive    (Default: false) Find PDF files in given directory

  -i, --input        Required. Input PDF files or directory

  -n, --number       (Default: false) Add page number to each page

  -f, --font         (Default: Aria) Font name for page number

  -s, --size         (Default: 8) Font size for page number

  -l, --location     (Default: bm) Location of page number, tl, tm, tr, bl, bm, br

  --format           Format of page number, $current and $total will be replaced

  -v, --verbose      (Default: false) Print verbose log

  --help             Display this help screen.

  --version          Display version information.

The location of the page number stands for "top left", "top middle", etc.

For the format option, you may need to use ' to quote it on Windows. For example, '$current / $$total' may be rendered as 2 / 5.

Note that it will automatically add .pdf extension to the output filename.

For example, you can use the following command to merge all PDFs under .\PDF as merged.pdf.

MergePdf.CLI.exe -o merged -i .\PDF

Based on that, you can add some extra arguments if you want to add page numbers on the bottom left of the PDF, with a larger font size and a custom format.

MergePdf.CLI.exe -o merged -i .\PDF -n -l bl -s 18 --format '$current / $total'

Building the project

The core library is MergePdf.Core, and MergePdf.CLI is the command-line client for it.

Just open the project in Visual Studio, and hit Build. I added some publish options to output final artifacts in the Publish/ folder under solution.
