Duplicate PDF Pages
Duplicate selected PDF pages and append them to the end
About this tool
Use selected ranges to append one to five additional copies. Page numbers are deduplicated and sorted into source order; the complete original stays first. One PDF with 1–80 pages and up to 20 MiB. One output PDF, up to 480 pages and 100 MiB. Forms, XFA, widgets, signature permissions and portfolios are rejected. Digital signatures do not remain valid; outlines, attachments and cross-page destinations are not rebuilt. Review ordinary annotations after downloading. PDF content is processed locally, with manual downloads after the complete operation succeeds.
Suggested Workflow
Scenario Recipes
Append repeated instruction sheets
Goal: Keep the six-page original, select 4,1,1 and choose two additional copies. The repeated 1 is collapsed; selection order follows the source, so each added set is A1,A4.
- Open the source and enter a nonempty list such as 4,1,1.
- Choose 2 additional copies and verify that the preview ends with 1,4,1,4.
- Confirm the order, generate and manually download the ten-page PDF.
Result: New PDFs match the reviewed source-page mapping and are downloaded manually for inspection.
Failure Clinic (Common Pitfalls)
Need a duplicate in the middle
Cause: This workflow appends every copy after the original pages.
Fix: Generate the copies first, then use the page organizer to move them; review every page once more.
Generated files disappear after a change
Cause: Output bytes belong to the source files and settings used to create them.
Fix: Review and generate again after changing options, order, sources, clearing or switching language. Old downloads do not continue.
A form or signed document is rejected
Cause: Forms, XFA, widget annotations, signature permissions and portfolios are rejected. Page copying does not preserve valid digital signatures or rebuild outlines, attachments and cross-page destinations. Ordinary annotations need output review.
Fix: Use an export or flattening workflow that explicitly supports those features, and retain the original document.

Are copies inserted beside the original page?
No. The complete original comes first, then each selected set is appended. Use the page organizer afterward to move copies into the middle.
What does selecting 4,1,1 with two additional copies produce?
The selection becomes pages 1 and 4 in source order, with duplicates collapsed. The appended pages are 1,4,1,4; the original pages remain unchanged at the start.
Can I duplicate an interactive form page?
Forms, XFA and Widget annotations are rejected because page copying does not preserve field relationships. A static unsigned instruction or answer sheet is a supported use case.
What are this tool’s file and page limits?
One PDF with 1–80 pages and up to 20 MiB. One output PDF, up to 480 pages and 100 MiB.
