PDFDeSecure

️ PDFDeSecure

PDFDeSecure is a free, open-source tool to remove restrictions from PDF files (e.g. printing, editing, copying), especially when DRM-like protections are applied.

Unlock your PDFs from "secured" printing mode in seconds.

✨ Features

• ✅ Removes PDF security restrictions (print/copy/edit)
• No need to know the password (if only usage rights are locked)
• Works on Adobe LiveCycle DRM-protected PDFs
• ️ CLI support and optional UI
• ⚡ Fast and lightweight — built with C#/.NET
• Cross-platform via .NET (Windows, Linux, macOS*)

Getting Started

Download

Grab the latest release from the Releases page.

Or clone the repo and build it yourself:

git clone https://github.com/abatsakidis/pdfdesecure.git
cd ./src/pdfdesecure
dotnet build

️ Usage

PDFDeSecure.exe

That’s it! Your output PDF will be unrestricted.

How it Works

PDFDeSecure bypasses usage restrictions by re-rendering the document as a new PDF, preserving layout and content while discarding the security flags.

⚠️ It does not attempt to crack password-encrypted PDFs (e.g. owner/user password protected).
