🚀 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 pdfdesecure
dotnet build

🖱️ Usage

PDFDeSecure.exe input.pdf output.pdf

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).
