Merge PDF Files

Combine several PDFs into a single document. Add your files, drag them into order, and download the merged PDF. It all happens in your browser — nothing is uploaded.

Merging

0 file(s)

Your file never leaves your device — everything runs in your browser, with no upload and no signup.

How it works

  1. Add two or more PDF files.
  2. Drag them into the order you want.
  3. Click merge — the files are joined into one.
  4. Your combined PDF downloads instantly.

Is it really free and private?

Yes. The whole operation runs in your browser using pdf-lib — no file is uploaded to a server, there is no watermark, and there is no signup.

Will the pages stay in order?

Yes. Files are merged top to bottom in the order shown, and every page inside each file keeps its original order.
