Complete Guide: VeryPDF DRM Free Version Limitations and How It Compares to Adobe Acrobat Pro Restrictions
If you’re considering using VeryPDF DRM Protector to secure and distribute your PDF content, especially for commercial purposes like selling ebooks or training materials on Amazon, it’s crucial to understand the limitations of the free version, how it works, and how it compares to Adobe Acrobat Pro’s PDF security features.
Below, we answer a series of common customer questions about VeryPDF DRM — particularly focusing on usage rights, user access, viewing limits, and printing controls.
1. Can I Use the Free Version of VeryPDF DRM to Upload Files for Sale on Amazon?
No. The free version of VeryPDF DRM Protector is for evaluation purposes only. It is not licensed for commercial use, which includes uploading protected PDFs for sale on Amazon, eBay, your own website, or any digital marketplace.
If you intend to distribute PDFs for commercial sale (e.g., ebooks, academic publications, manuals), you’ll need to upgrade to the commercial license version to remove these usage restrictions.
2. What Are the Limitations on Users and Views in the Free Version?
When using the free version:
-
You can allow up to 50 users to open and view your protected PDF files.
-
There is a maximum of 100 total views allowed across all users.
✅ Example: If 50 users each view the PDF twice, your 100-view limit is reached.
Once the limit is reached, no further views are allowed, and the file becomes inaccessible unless you upgrade to the full version.
3. What Happens if a User Downloads the Protected PDF? Can They Keep Viewing It?
Even if someone downloads a VeryPDF DRM-protected file, the file is encrypted and bound to user authentication. This means:
-
The user must be online and authenticated via the VeryPDF DRM Server each time they want to open the file.
-
The viewing and user limits still apply — downloading does not bypass them.
So yes, the DRM remains intact. You, as the content owner, retain full control over access, even post-download.
4. Is There a Limit on How Many Times One User Can View the File?
Yes. Since the 100-view limit is shared across all users, each user’s access counts toward this total. For instance:
-
If 10 users open the document 10 times each, the view quota is used up.
-
You can’t set unlimited views per user in the free version.
For greater flexibility — such as per-user limits, unlimited views, or advanced access control — you’ll need to use the paid version of VeryPDF DRM Protector.
5. Can I Restrict Printing for Only Part of a PDF File?
Currently, printing restrictions apply to the entire document. Partial printing control (e.g., blocking print for specific pages or chapters) is not supported in the current version.
This feature may be considered for future updates, but as of now, you can either allow or block printing for the whole file.
6. How Is VeryPDF DRM Different from Adobe Acrobat Pro’s PDF Restrictions?
This is a great question. While both tools are designed to protect PDF content, they differ significantly in how protection is enforced and how secure that protection really is.
Here’s a detailed comparison:
Encryption and Security Strength
-
Adobe Acrobat Pro: Uses standard PDF permissions (e.g., no print, no copy), which are often easily bypassed by third-party tools.
-
VeryPDF DRM: Uses AES 256-bit encryption, dedicated DRM readers, and server-side authentication, making it nearly impossible to crack with standard tools.
Remote and Dynamic Access Control
-
Adobe: Once a PDF is shared, you lose control over its use.
-
VeryPDF DRM: Allows remote control — set expiration dates, revoke access, limit number of opens, and more — even after distribution.
User-Based Licensing and Tracking
-
Adobe: No user-specific access control.
-
VeryPDF DRM: Each user gets a unique license. You can track activity, revoke access for individuals, and see usage logs.
️ Reader Dependency
-
Adobe: Relies on Adobe Reader.
-
VeryPDF DRM: Uses its own Windows DRM reader or online reader, completely blocking other software from opening or extracting content.
7. What Are Ideal Use Cases for VeryPDF DRM Over Adobe Acrobat Pro?
VeryPDF DRM is especially suitable for:
-
Selling PDF eBooks or academic textbooks online
-
Distributing internal corporate documents with limited access
-
Licensing research reports or training manuals
-
Preventing sharing among students or unauthorized resellers
Its server-based access control and stronger encryption make it a more powerful solution for digital rights management (DRM) than Acrobat Pro, especially in high-risk, commercial, or educational use cases.
