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.

使い方

  1. Add files from File Explorer

    Drag PDF files from a File Explorer window onto the upload area above, or click to browse.

  2. Put them in order

    Drag the file cards into the order the documents should appear.

  3. Merge

    Click Merge PDFs, optionally adding a bookmark for each file.

  4. 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.

活用シーン

Expense claims

Combine invoices and receipts saved from Outlook into one PDF for a claim.

Scanned paperwork

Merge pages scanned separately with Windows Scan into a single document.

トラブルシューティング

Files appear in the wrong order

Drag the cards into the right order before merging, or rename files with numbers (01, 02) so they sort correctly.

A PDF will not load

It may be password-protected. Unlock it with Decrypt PDF first.
