Why "no upload" matters for PDFs

The files people merge are rarely trivial. They are contracts, invoices, bank statements, medical records, passports, tax returns. Most free "merge PDF" websites ask you to upload those documents to their servers before they touch them — your file sits on someone else's machine, subject to their retention policy, their breaches, and their jurisdiction.

This tool never does that. The merging runs as JavaScript inside your own browser tab. You can prove it: turn off your Wi-Fi after the page loads and merge anyway — it still works.

How to merge PDFs here

Drop in two or more PDF files (or click to browse).
Drag the rows to put them in the order you want.
Press Merge & download. The combined file saves straight to your device.

Does merging reduce quality?

No. Pages are copied across as-is — text stays selectable, images keep their original resolution, and vector graphics stay vectors. Merging is not a re-render, so nothing is degraded.

What about encrypted or password-protected PDFs?

A PDF locked with a password cannot be read without it, so it cannot be merged here. Remove the password in your PDF reader first, then merge.

Is there a file-size limit?

There is no server limit, because there is no server. The practical limit is your device's memory — very large scanned documents may be slow on older phones.

Processing happens entirely in your browser. Always keep a copy of your original files before combining them.
