Duplicate PDF Pages
Duplicate PDF Pages starts with all source pages, then inserts one copy after each selected physical page while tracking earlier insertions. Selection itself is deduplicated, so each selected original gains at most one additional copy. The operation can affect links, page labels, forms, and signatures.
Runs locally — files stay on your deviceWhat does selecting pages 2 and 4 produce?
The order becomes 1,2,2-copy,3,4,4-copy,… with insertion offsets accounted for.
Insertion shifts later page positions
The implementation records original zero-based indices, then adds an increasing offset so each copy stays after its source despite previous insertions.
How it works
All pages are copied, each selected source page is copied again, and insertPage places it after the corresponding original position.
Key concepts
Selected numbers refer to the original
They are parsed before any insertions.
Copied interactive content can conflict
Form field names and annotations may share document-level relationships.
When to use it
- Create an intentional repeated form page.
- Duplicate a cover or worksheet.
- Add one copy after selected pages.
When not to use it
- Do not expect more than one duplicate per selected page.
- Do not use output indices as if they were original positions.
- Do not assume form fields remain independent.
Worked examples
One duplicate
- Input
2- Expected output
1,2,2-copy,3…
The copy follows page 2.
Two selections
- Input
2,4- Expected output
Copies after original 2 and 4
Offset prevents misplacement.
Repeated entry
- Input
2,2- Expected output
One extra copy
Selection deduplicates.
Common mistakes
Entering the desired new position
Inputs reference source pages. Correction: Select original page numbers.
Expecting multiple copies
Duplicates are removed from selection. Correction: Run again or use dedicated imposition software.
Ignoring form fields
Duplicate field names can behave unexpectedly. Correction: Test interactive documents.
Best practices
- Count output pages.
- Test forms and internal links.
- Use static documents when possible.
