## Removing page-level actions from PDF
1730+
1731+
Removes page‑level actions from PDF documents by disabling actions triggered on page open and page close events, ensuring that pages no longer execute automatic behaviors while preserving existing annotation actions where required.
1732+
1733+
Refer to the following code example for removing PDF page‑level actions.
