How to Combine PDF Files on Windows
Windows 10 and 11 can open and print PDFs in Microsoft Edge, but they have no built-in command to merge them. The tool on this page fills that gap: drop your PDFs here, arrange them and click Merge PDFs. It runs in Edge, Chrome or Firefox and combines the files on your PC without uploading them.
Before you start
- Where your file is processed
- In your browser. The file is read and processed on your device and is not uploaded to PDFYork.
- Account
- Not required. Without an account you can run 3 tasks per day across all tools. A free account raises the limit.
- Cost
- Standard tool. Free accounts can run 14 standard tasks per day.
How to Use
Add files from File Explorer
Drag PDF files from a File Explorer window onto the upload area above, or click to browse.
Put them in order
Drag the file cards into the order the documents should appear.
Merge
Click Merge PDFs, optionally adding a bookmark for each file.
Download
Save the combined PDF. Edge and Chrome put it in your Downloads folder unless you chose another location.
Why Windows needs a separate tool
Microsoft Edge is the default PDF viewer on Windows and can view, annotate and print PDFs, but it cannot combine several files into one. "Microsoft Print to PDF" also prints only one document at a time. To merge, you need either a desktop PDF application or a browser-based tool such as this one.
Selecting many files quickly
- In File Explorer, hold Ctrl and click each PDF, or click the first and Shift-click the last to select a range.
- Drag the whole selection onto the upload area in one go.
- Files are added in the order Windows passes them, so check the order of the cards before merging.
Privacy on shared or work PCs
The merge runs inside your browser tab, so the PDFs are not uploaded to PDFYork. The combined file is saved wherever your browser saves downloads; on a shared computer, move it somewhere private and clear the Downloads folder afterwards.
Next steps: compress the result if it is too large to email, or add a password before sending it.
