About Merge PDFs
Merge PDFs joins several PDF files into one continuous document in the order you provide them. Reach for it when a report, contract, or application is split across multiple files and you need a single deliverable. The merge runs in your browser, so confidential documents never get uploaded.

Frequently asked questions
How many PDFs can I merge at once?
As many as you like; the only practical limit is your device's available memory since the work happens locally.
Does merging keep the original page order?
Yes. Files are concatenated in the order you add them, and each file's internal page order is preserved.
Are my documents uploaded to a server?
No. Merging is done entirely in your browser, so even sensitive contracts stay on your machine.
Will merging change the quality of the pages?
No. Pages are copied as-is, so text stays selectable and images keep their original resolution.
Can I merge password-protected PDFs?
Encrypted PDFs must be unlocked first. Run them through Decrypt PDF, then merge.
