Cap the number of opens
Stop the route after the chosen number of reads.
Use MaiPDF when the PDF needs to be opened through a controlled browser route with limits, view mode, expiry, and later records, rather than being sent as a plain attachment.
MaiPDF keeps the rules on the share route itself, so the owner is not just stamping the file and hoping for the best.

Start with the document that should stay in a controlled route.
Choose the mode and the reading constraints before launch.
Readers open the governed link or QR instead of getting a loose file.
The owner keeps the after-sharing control layer.
SecureView and FenceView add friction before the file ever leaves the system.
Read count and time windows can stop the route after a fixed amount of use.
The owner keeps a browser-based share instead of relying on a detached PDF copy.
History and later actions stay attached to the same reading code.
Keep the page on the handful of settings that define whether the share feels controlled or loose.
Stop the route after the chosen number of reads.
Use SecureView or FenceView instead of handing over a raw download path.
Define how long each viewing session can last.
Let the share stop after the chosen date or duration.
That is the practical difference: the rule set stays on the same route the owner can still inspect later.
Read constraints
Access limit and per-session timing are configured before the share goes out.
Security mode
The owner chooses the viewing mode in the same setup flow instead of using a separate tool.

Mask most of the page so screen grabs lose value.
Stamp the viewer's identity on every page.
Deliver the same share link through a scannable code.
The end-to-end flow for sending files with controls.
