Merging

0 file(s)

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

How can you combine PDF files for free?

  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.

What order will the merged PDF pages follow?

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

How do you check the combined PDF?

Open the downloaded file and check the first page, the boundaries between files, and the final page. The total page count should match the sum of the pages in the input PDFs.
