Merge PDF files

Combine PDFs in the order you want — without uploading them anywhere. The merging happens in your browser, on your device. Free, no account, no watermark.

Open your network tab while merging: zero requests. Your documents stay yours.

How to merge PDF files

  1. Select or drop your PDFs — pick as many files as you need; they're read by your browser, not sent to a server.
  2. Put them in order — drag the thumbnail cards; the merged file follows the numbers, left to right.
  3. Merge → download — one click creates merged.pdf on your device. Pages are copied exactly, nothing is re-compressed.

Most online PDF mergers upload your documents to their servers to do this work. For contracts, medical records, or anything private, that's a real cost. This merger is different by architecture: the same technology that powers our PDF to Markdown converter and PDF chat runs the merge locally, so the file that never leaves your machine is the point, not a promise.

Merging PDFs, answered honestly.

No. This merger runs entirely inside your browser — the files are read, combined, and downloaded on your own device. You can open your browser's network tab while merging: zero requests. That's different from most online PDF mergers, which upload your documents to their servers first.
Add your PDFs, then drag and drop the thumbnail cards to arrange them — the merged file follows the numbers on the cards. You can add more files or remove any file before merging.
No hard limit — because the work happens on your device, the practical limit is your computer's memory. Hundreds of pages merge in seconds on a normal laptop.
Not yet. Encrypted PDFs are detected and skipped with a note, so they never silently corrupt your merged file. Unlock them first, then merge.

No. Pages are copied into the new file as-is — text, images, and vector content are preserved exactly. Nothing is re-compressed.
