Merge PDF

Combine multiple PDF files into one. Drag to reorder before merging.

What is the Merge PDF?

The Merge PDF tool combines two or more PDF files into a single document, preserving the exact layout, fonts and images of every page. Drag files into the order you want and the merged PDF is generated on your device — no account, no watermark.

Merging runs locally in your browser, so contracts, medical records and tax documents never sit on a server.

How to use the Merge PDF

  1. 1Drag your PDF files onto the upload area (or click to browse).
  2. 2Reorder the files with the up/down arrows — list order becomes page order.
  3. 3Remove any file added by mistake with the × button.
  4. 4Click "Merge PDFs" and the combined file downloads as merged.pdf.

Frequently asked questions

Is there a limit on the number of PDFs?

No hard limit — practical limits depend on your device's memory. Merging 50–100 PDFs typically works fine.

Can I reorder pages after merging?

Reorder files before merging; afterwards, use Split PDF or Remove PDF Pages for further adjustments.
