Merge PDF — Combine PDF Files
Drop two or more PDFs, arrange the order, and download one combined file — nothing is ever uploaded.

Merging happens entirely in your browser — your PDFs are never uploaded. Password-protected PDFs aren't supported.
How it works
Most online PDF mergers upload your documents to a server — contracts, statements,
IDs — and hand back a download link, which means your files sit on someone else's
machine. This one merges entirely in your browser instead. Pages are copied
losslessly at original quality, in whatever order you arrange the files with the
up and down buttons, and you download a single merged.pdf that never left your
device.
FAQ
Do you upload my PDF files?
No. Merging is done by JavaScript in your browser using the pdf-lib library. Your files never touch a server, so there is no queue, no watermark, and no privacy risk.
Is there a limit on file count or size?
Only your device's memory. Because everything runs locally there is no artificial page or file limit — very large PDFs just take a moment longer.
Why can't I merge a password-protected PDF?
Encrypted PDFs can't be read without the password, and this tool never asks for one. Remove the protection in your PDF reader first, then merge.
