How to Merge PDF Files Online for Free

Combining a few PDFs into one file is one of the most common everyday tasks, like merging scanned pages, contracts, or reports into a single document. Most online mergers make you upload your files to a server first, which is unnecessary and slow. Our Merge PDF tool runs entirely in your browser, so your files never leave your device.

  1. 1Open the Merge PDF tool.
  2. 2Drag and drop your PDF files, or click to choose them from your device.
  3. 3Drag the file list to reorder pages exactly how you want them to appear in the final document.
  4. 4Click the merge button and your combined PDF downloads immediately.

Frequently asked questions

Is there a limit to how many PDFs I can merge?

No artificial limit. Since everything runs locally in your browser, you can merge as many files as your device's memory allows.

Do I need to install anything?

No. It works directly in your browser on any device, including desktop, phone, or tablet, with no software or account required.

Will merging keep my original files intact?

Yes. Your original PDFs are never modified. The tool reads them locally and creates a new, separate combined PDF for you to download.
