About PDFtk

For ten years, power users have relied on PDFtk for server-side processing of PDF documents. Our command-line PDFtk has been — and always will be — free (as in freedom) software.

Today we also offer a convenient graphical application: PDFtk Pro. Your purchase of PDFtk Pro will help fund the continued development of our GPL PDFtk.

Thank you for your support!
