Merge PDF Files Online — Combine into One PDF

Scanned contracts in five files? Reports in chapters? Combine PDFs into one tidy document — privately.

Scanned contracts arrive as five separate files, reports come in chapters, receipts pile up — merging them into one PDF makes everything archivable and emailable. Most "free" mergers upload your documents to their servers first, which is a non-starter for contracts, medical forms, or financial statements.

The faymox merger combines PDFs with pdf-lib running entirely in your browser. Your documents never leave your device, there are no page-count games, and you control the final order before merging.

Merge PDFs in 3 steps

  1. Drop your PDF files into the Merge PDF tool, in the order you want them.
  2. Review the file list and reorder if needed.
  3. Merge and download the single combined PDF.

FAQ

Is there a page limit?

No artificial limit — the practical bound is your browser's memory. Everyday documents merge in seconds.

Can I change the order of the PDFs?

Yes. Add the files in the sequence you want; the merged PDF follows that order.

Is it safe for sensitive documents?

The merge happens locally in your browser tab. Unlike server-side mergers, your files are never transmitted anywhere.
