Practical help
Questions before you run it
What exactly does Duplicate PDF Pages change?
The processor walks the source once and inserts a second copy immediately after every selected page. The processor operates only on the selected document structure and returns a new download. It does not overwrite the source file on your device, infer missing instructions, or approve the result for legal, archival, accessibility, or production use. Compare the output with the original before relying on it.
What input and limits apply to Duplicate PDF Pages?
One unlocked PDF up to 500 pages plus a page expression such as 1,3-5. The combined request is limited to 10 MB, each inspected PDF is limited to 500 pages, and generated output is limited to 50 MB. Password-protected documents must be unlocked first. Complex or malformed structures can still require a specialist desktop PDF application and a manual review.
What should I verify after using Duplicate PDF Pages?
Confirm the downloaded file opens, then inspect page count, page order, orientation, visible marks, interactive elements, and any content relevant to the task. Duplicated pages can repeat page labels, links, fields, signatures, or logical identifiers that require manual correction. Keep the original until the result has been reviewed in the destination viewer, print workflow, records system, or other environment where it will actually be used.
