DRMZ is a secure proprietary file format, which is created by Drumlin Publisher in order to protect Adobe PDF (Portable Document Format) Files and make them more secure. The Drumlin Publisher software exports PDF files to DRMZ or DRMX file format. It makes the PDF file more secure by adding proprietary encryption OR encoding system. The PDF file is encrypted/encoded from the header and encapsulated in DRMZ file.

Note: The DRMZ file is similar to the DRMX file; the only difference lies in their compatibility with devices.
