PDF Blue Security is a powerful PDF DRM solution that helps schools, publishers, course creators, businesses, and institutions protect their PDF files. Control viewing, printing, device access, IP restrictions, hidden pages, and virtual printers — maintaining full control over your documents long after they have been delivered to the recipient.
With PDF Blue, you decide who can open the file, how many times it can be viewed or printed, on how many machines, and from which IP addresses. You can hide pages, expire users and documents, block virtual printers, block printing to PDF, and unlock pages later when you're ready.
Create users with their own credentials, dynamic watermarks, and expiration dates. Revoke access in seconds, even after the file is delivered.
Limit views, limit prints, limit how many machines can ever open the document. Block "Print to PDF" and virtual printers.
Restrict reading to specific IP ranges. Useful for in-classroom material, corporate documents, or VPN-only access.
Stamp each opened PDF with the user's name, email, machine ID or any custom field. Discourage sharing and trace leaks.
Hide specific pages from your readers. Unlock them later, automatically or with a click — perfect for staged content release.
Bulk-create and edit users with spreadsheets. Update files in batches. Manage thousands of readers without manual work.
Your readers can drag any .pdfblue protected file into pdfbluesecurity.com/reader and view it instantly — on Windows, Mac, Linux, iPad or Android. Same rules, same watermarks, zero install.
See every open, every print, every device activation. Know who opened what, when, and from which IP — for compliance, support, and tracing any leak back to its source.
Set an expiration date on any user or any individual file. After the date, the PDF stops working everywhere — automatically, with no need to revoke access by hand.
Set their limits — view, print, machines, expiration. Define a dynamic watermark with their data. Import in bulk from a spreadsheet if you have a lot of them.
Drop your PDFs into Control. Each protected file is encrypted and bound to the rules you configured. Decide who can open which file.
Readers can use the free PDF Blue Reader Desktop (Windows, includes printing) or just open the file in their browser through PDF Blue Reader Web — no installation, works on Windows, Mac, Linux, iPad and Android. Both enforce the rules you set in real time.
If you came here looking for any of the answers below, you're in the right place — PDF Blue Security was built exactly for these scenarios.
PDF Blue blocks text copy, image extraction and virtual printers (including "Microsoft Print to PDF") at the reader level. No password to crack — real DRM enforcement that travels with the file.
Each protected PDF is bound to specific users, machines and IP addresses. Even if the file leaks, it won't open for anyone you didn't authorize. Revoke access in seconds from PDF Blue Control.
Dynamic watermarks burn the reader's name, email, machine ID and IP into every page. Leaks become traceable, and the threat alone discourages most sharing attempts before they happen.
A complete DRM stack: encryption, per-user credentials, view and print limits, device locking, IP restrictions, expirations and watermarks. The same toolkit used by Locklizard / Vitrium / VeryPDF customers — at a fraction of the price.
Set a per-user print limit (including zero), block virtual printers and "Print to PDF", and authorize physical printing only when you choose. Print attempts are logged.
Add an expiration date to any protected file or any user. After the date, the PDF stops working everywhere — perfect for time-limited course access, exam materials, internal drafts and confidential reports.
Choose your plan based on how many users and protected files you need. Upgrade or downgrade at any time. Cancel whenever you want.
