How to Merge PDFs on Windows Without Installing Software

Windows has no built-in PDF merger. Here is how to combine PDF files for free in your browser on Windows 10 and 11.

Updated October 9, 2026

Quick steps

  1. Open Merge PDF in Edge, Chrome, or Firefox.
  2. Select the PDF files from File Explorer, or drag them onto the page.
  3. Drag the file cards into the order you want.
  4. Rotate any sideways documents with the rotate button.
  5. Click Merge and download to save the combined PDF.

Windows 10 and 11 can open PDFs in Microsoft Edge, but neither includes a way to combine several PDFs into one. Most guides recommend installing a desktop app. You do not need to.

Merge PDFs in your browser

  1. Open Merge PDF in Edge, Chrome, or Firefox.
  2. Click Select PDF files and pick the documents in File Explorer. Hold Ctrl to choose several at once, or drag them straight onto the page.
  3. Drag the cards into the order you want.
  4. Click Merge and download. The combined file is saved to your Downloads folder.

The merge runs inside the browser, so the files never leave your PC. That also means it works on locked-down work laptops where you cannot install software.

Why not Print to PDF?

Microsoft Print to PDF turns one printable document into a PDF. It cannot take several existing PDFs and join them, and printing a PDF to PDF can flatten text into images and drop links. Use a real merge tool instead.

Combining only some pages

If you only need certain pages from each document:

  1. Use Extract Pages to pull out the pages you need from each file.
  2. Merge the extracted files.
  3. Fine-tune the final order in Organize PDF.

Tips for clean results

  • Name files in order (01-cover.pdf, 02-report.pdf) so selecting them all keeps the right sequence.
  • Check orientation before merging. Landscape pages in a portrait document are easy to fix with the rotate button on each card.
  • Compress afterwards if the merged file needs to go by email; see How to reduce PDF size for email.

Frequently asked questions

Can Microsoft Edge merge PDFs?

Edge can open, annotate, and print PDFs, but it does not have a feature for combining several PDF files into one.

Can I use Microsoft Print to PDF to merge files?

Not for existing PDFs. Print to PDF creates a PDF from a single document you print, and it cannot combine multiple PDF files.

Is there a file limit?

There is no fixed limit. Because merging happens in your browser, very large batches depend on your computer's available memory.
