TDMRep Protection
Control whether AI and machine learning systems may access and mine your PDF content.
Overview
The TDMRep Protection tool embeds a text-and-data-mining (TDM) rights reservation and an optional policy URL into a PDF document's XMP metadata, using the W3C TDM Reservation Protocol properties (tdm:Reservation and tdm:Policy). This lets content owners declare whether their content may be used for text and data mining, including AI/ML training, and supports reserving rights under the EU DSM Directive Article 4. Because it writes the standard in-document TDMRep encoding, the reservation is recognised by TDM-aware crawlers and tools that read PDF XMP. Any existing metadata in the document is preserved — the TDM properties are merged into the existing XMP packet.
How to Use
- Navigate to TDMRep Protection from the Security & Optimization menu.
- Upload your file using drag-and-drop, Browse Files, or cloud storage (Dropbox / Google Drive).
- Configure your TDM reservation preferences.
- Click Apply to process.
- Download the result when processing completes.
Options

Tips & Notes
This is a signal, not access control. The reservation records your preference but does not technically prevent mining or copying. Combine with Protect PDF for additional security.
The reservation is stored as standard W3C TDMRep properties in the document's XMP metadata, so it can be read by any TDM-aware crawler or tool — as well as by the Check Protection tab here. Note that TDMRep is a declaration of rights, not a technical access control: honouring it depends on the consuming party respecting the protocol.
