Repeat Entire PDF
Duplicate the entire PDF document 2-20 times in one file
About this tool
Repeat Entire PDF duplicates the whole PDF document end-to-end by a multiplier of your choice (2x to 20x). Unlike Duplicate Pages which only copies selected pages, this workflow repeats every page of the source file in the same order, then concatenates them into one output PDF. Common scenarios include batch printing of multi-page forms, generating multi-copy handouts for events, and producing larger test files to validate downstream pipelines. The repeat count is capped at 20x to keep file size reasonable; for very high multipliers, expect linear growth in output size. All processing happens locally in your browser using pdf-lib; the source file never leaves your device. Maximum input file size is 50 MB.
Frequently Asked Questions
Why is the repeat count capped at 20x?
Higher multipliers grow file size linearly. 20x is a balance between common use cases and reasonable output size.
Are pages reordered or kept in original sequence?
Original sequence is preserved. The output is N copies of the source PDF concatenated in order.
What is the difference between Repeat PDF and Duplicate Pages?
Repeat PDF copies the entire document. Duplicate Pages copies only the page ranges you specify. Use Repeat PDF when every page should repeat.
Is my PDF uploaded to any server?
No. All processing is done locally in your browser using pdf-lib. The file never leaves your device.
What is the file size limit?
50 MB for the input PDF. Output size scales with the repeat count, so a 5 MB file repeated 20x produces roughly 100 MB.
Can I use this for stress testing larger PDFs?
Yes. Repeating a small valid PDF many times is a common way to generate large test files for upload/processing pipelines.
Does this work with password-protected PDFs?
No. Remove the password first using an unlock workflow, then repeat the cleartext PDF.
