Zero Upload

Your PDFs never leave your device. Everything is processed by your browser using pdf-lib — no server involved.

Instant Results

No upload time, no processing queue. Merging happens on your machine — even a 10-file merge takes seconds.

FAQ

Common questions answered.

Correct — 100%. This tool uses pdf-lib, a JavaScript library that runs entirely in your browser. Your files are read from your disk directly by your browser and merged in memory. Nothing is sent over the network.
No server limits — only your device's memory. Very large PDFs (hundreds of MB) may be slow depending on your computer, but there's no hard limit imposed by this tool.
Yes — drag any file row up or down to reorder before merging. PDFs are merged in the exact order shown in the list.
Password-protected PDFs cannot be merged — you'll see an error for that file. Remove the password protection first using your PDF viewer, then try again.
No — pdf-lib copies pages as-is at full quality. There is no re-encoding, compression, or quality loss during the merge process.
