When this tool is useful
Maintaining a straightforward chapter list in a PDF whose outline already uses direct, top-level physical-page destinations.
How local processing works
The tool accepts only a supported top-level sibling chain with direct page-array destinations, applies the requested list change, rewrites that flat outline with direct Fit destinations, and reopens it for exact comparison.
How to use it

- Download and verify: Expand the outline in the target viewer, click every bookmark, compare its title and physical page with the requested list, and confirm that the normalized flat order is acceptable.
Important limitations
Nested children, named destinations, action-based or remote destinations, mixed structures, cycles, malformed links, and signed PDFs are rejected rather than guessed or partly rewritten. Destination zoom and view modes are normalized to Fit.
