Library for merging multiple PDFs

pdfmerger

PHP library for merging multiple PDFs using FPDI, _(*1)

Based on PDFMerger created by Jarrod Nettles December 2009, _(*2)

https://pdfmerger.codeplex.com/, _(*3)

Class for easily merging PDFs (or specific pages of PDFs) together into one. Output to a file, browser, download, or return as a string., _(*4)

Unfortunately, this class does not preserve many of the enhancements your original PDF might contain. It treats your PDF page as an image and then concatenates them all together., _(*5)

Note that your PDFs are merged in the order that you provide them using the addPDF function, same as the pages., _(*6)

If you put pages 12-14 before 1-5 then 12-15 will be placed first in the output., _(*7)

• Uses FPDI 1.4.4 from Setasign
• Uses FPDF 1.6 by Olivier Plathey with FPDF_TPL extension 1.2.3 by Setasign
• FPDI extension to preserve external hyperlinks https://gist.github.com/andreyvit/2020422

All of these packages are free and open source software, bundled with this class for ease of use., _(*8)

Installation

Install using composer., _(*9)

composer require erc/pdfmerger
