Add multiple PDFs — drag to reorder

How to merge PDFs

  1. Click the upload area or drag multiple PDF files onto it.
  2. Drag the file rows to reorder them — the final PDF will follow this order.
  3. Click Merge PDFs and the combined file downloads instantly.

Why merge PDFs in the browser?

Other PDF merger tools send your files to a server, which raises privacy concerns — especially for invoices, contracts, or personal documents. This tool uses pdf-lib entirely in your browser. Your PDFs never leave your device.

Frequently Asked Questions

How do I merge PDF files for free?
Upload two or more PDFs, drag to reorder if needed, then click Merge. The combined PDF downloads instantly — no signup, no upload to any server.
Is there a limit on the number of PDFs I can merge?
No hard limit — the tool runs in your browser, so the only constraint is your device's memory. Merging dozens of PDFs at once works fine on modern computers.
Are my PDF files safe when merging?
Completely. Everything happens inside your browser tab. No file is ever transmitted to a server.
