Combine PDFs without uploading your documents
Most online PDF mergers upload your files to their servers — a real concern when you're combining contracts, medical records, or financial statements. This tool merges PDFs entirely in your browser, so your documents never leave your computer.
Add as many PDFs as you need, drag them into order with the arrows, and download a single combined file. No watermarks, no page limits, no account.
How to merge PDF files
- Drop two or more PDFs into the box above.
- Reorder them with the ↑ and ↓ buttons.
- Click “Merge” and the combined PDF downloads immediately.
Frequently asked questions
Are my PDFs uploaded to a server?
No — and for documents this matters. Contracts, statements, and IDs are processed entirely in your browser. Nothing is transmitted anywhere.
Can I change the order of the files?
Yes. Use the up/down arrows next to each file to arrange them before merging. Pages appear in the final PDF in exactly the order shown.
Is there a file size or page limit?
No hard limits. Because merging happens on your device, very large PDFs are only constrained by your computer's memory.
Do password-protected PDFs work?
Encrypted PDFs that require a password to open can't be merged. Remove the password first, then merge.
