How to Merge PDF Files (Browser-Based)
Merging PDFs is common for contracts, scanned receipts, and report appendices. Browser-based merge keeps files on your device, which matters for sensitive documents.

Steps to merge PDFs
Select two or more PDF files in the order you want pages to appear. Reorder files before merging if page sequence matters.
Click merge and download the combined PDF. Processing runs locally; nothing is sent to a server.
If a file fails, try exporting it again from the source app or printing to PDF to normalize the file.

Is there a page limit?
Very large files depend on browser memory. Merge reasonable batch sizes for reliability.
Can I merge password-protected PDFs?
