Files never leave your device

Merge PDF Files Online

Combine any number of PDFs into a single document, in any order. Files are processed entirely in your browser — never uploaded.

How to use PDF Merge

  1. Drop your PDFs onto the upload area, or click to browse.
  2. Drag the file cards to put them in the order you want.
  3. Optionally remove any file you added by mistake.
  4. Click "Merge" — the combined PDF downloads automatically.

When to merge PDFs

The most common case: assembling a packet to send. A loan application that needs five separate PDFs combined into one; a meeting briefing built from a half-dozen docs; an invoice plus receipts that the accounts team wants as a single attachment. Almost every desktop PDF tool can do this — but they want a subscription.

Why not use a server-based site?

Plenty exist. They all upload your files. If you're combining anything sensitive — a contract, a medical record, a tax document — that's the wrong move. This tool does the same merge in your browser, takes a fraction of a second on a modern laptop, and the file never leaves your device.
