About Merge PDF
Merge PDF combines two or more PDF files into a single document. Pages are copied from each selected file and added in the same file order, making it useful for combining reports, invoices, assignments, forms or project documents into one shareable PDF.
Before merging, choose the files in the order you want them to appear in the final document. The tool combines pages rather than visually re-rendering them, which helps preserve the original PDF page content. Encrypted or damaged PDFs may need to be repaired or unlocked before they can be merged.

Frequently Asked Questions
How many PDF files can I merge?
You can select multiple PDF files. Practical limits depend on your browser memory and the size of the documents.
Does Merge PDF change the order of my files?
The merged document follows the order of the files you selected.
Will merging reduce PDF quality?
The merge operation copies PDF pages into a new document instead of intentionally rasterizing them, so it is not designed to reduce page quality.
