I keep sending PDFs that get modified and redistributed, and I need a way to limit changes.

Add PDF protection controls to reduce unauthorized edits and deter redistribution of modified copies. This helps ensure recipients view the document as intended and preserves the integrity of what you send.

This feature helps you limit changes to PDFs you share by applying document protection settings before sending or distributing them. It is designed for situations where recipients may edit content, remove pages, or repackage your PDF and forward a modified version. You can use it to make the PDF harder to alter by restricting editing actions and discouraging tampering. It supports common sharing scenarios such as sending proposals, contracts, reports, price lists, or brand assets where accuracy matters. By limiting modification, you reduce the risk of misinformation, misrepresentation, or accidental edits being mistaken for the original. The feature also helps maintain consistency across versions when a document is shared with many recipients. It is especially useful when PDFs are distributed externally, posted to portals, or attached to email threads that get forwarded. The intended outcome is that recipients can read and use the PDF while having fewer opportunities to change its contents. Overall, it provides more control over how your PDFs are consumed and reduces the chance that altered copies circulate under your name.
