pdfcpu: a Go PDF processor

pdfcpu is a simple PDF processing library written in Go supporting encryption. It provides both an API and a CLI. Supported are all versions up to PDF 1.7 (ISO-32000).

Motivation

This is an effort to build a comprehensive PDF processing library from the ground up written in Go. Over time pdfcpu aims to support the standard range of PDF processing features and also any interesting use cases that may present themselves along the way.

Focus

The main focus lies on strong support for batch processing and scripting via a rich command line. At the same time pdfcpu wants to make it easy to integrate PDF processing into your Go based backend system by providing a robust command set.

Command Set

• attachments
• change owner password
• change user password
• decrypt
• encrypt
• extract
• grid
• import
• info
• merge
• nup
• optimize
• pages
• permissions
