Using a Free Browser Tool — Fastest Method

This is the easiest and most reliable way to combine PDF files on Windows free — no software to install, works on both Windows 10 and Windows 11, and gives you full drag-and-drop control over file order. Your PDFs are processed entirely inside your browser — nothing is uploaded to any server.

Best for: Everyone. Works in Edge, Chrome, Firefox, and Opera on any Windows PC or laptop.

1
Open Edge or Chrome on your Windows PC

Both browsers are pre-installed on modern Windows computers. Edge comes with Windows 10 and 11 by default.

2
Go to rapidtools.online/merge-pdf

Type the address in the browser bar and press Enter. No sign-up or account needed.

3
Drag your PDF files onto the upload zone

Open File Explorer, find your PDFs, and drag them directly onto the browser window. Or click the upload zone to browse and select files. You can add multiple PDFs at once from different folders.

4
Arrange in the correct order

Use the ↑ ↓ arrow buttons on each file card to set the order. The top file becomes page 1 of the merged document.

5
Click Merge PDFs

Processing happens instantly in your browser. A progress indicator appears, then the download starts automatically.

6
Find your merged PDF in Downloads

The file saves to your Windows Downloads folder by default. Press Ctrl + J in the browser to open the downloads list and click the file to open it.

💡 Windows tip: You can drag PDFs directly from the Windows taskbar or desktop onto the browser window. Hold Ctrl while clicking in File Explorer to select multiple PDFs at once before dragging.
⚠️ Privacy note: RapidTools processes your PDFs locally in your browser — files never leave your PC. Unlike most online PDF tools which upload your files to their servers, RapidTools uses JavaScript to merge everything on your device.

Microsoft Edge Print to PDF Trick

Microsoft Edge — which comes pre-installed on every Windows 10 and Windows 11 PC — has a hidden feature that lets you combine PDFs using the Print dialog. It's a workaround rather than a dedicated merge tool, but it requires zero downloads and works entirely offline after Edge is open.

Best for: Quick 2-file merges on Windows 10/11 where internet isn't available. Windows 10 / 11

1
Open your first PDF in Microsoft Edge

Right-click the PDF file in File Explorer → Open with → Microsoft Edge. Edge opens PDFs natively.

2
Open Print dialog

Press Ctrl + P to open the print dialog, or click the three-dot menu → Print.

3
Select "Microsoft Print to PDF" as the printer

In the printer dropdown, choose Microsoft Print to PDF — this is built into Windows 10 and 11. Set pages to "All".

4
Print and save

Click Print. Windows asks where to save the PDF — choose your folder and name the file. Repeat for your second PDF.

5
Use the browser tool to combine the two saved PDFs

The Print to PDF method is best for preparing and cleaning individual files. To combine them, use Method 1 — the browser tool gives you full control over the merge order.

⚠️ Limitation: Edge's Print to PDF doesn't directly combine multiple PDFs into one — it re-saves individual files. For direct merging with order control, Method 1 is faster and simpler.
3

Windows Photos App — For Images Only

If your documents are images (JPG, PNG, screenshots) rather than existing PDFs, the Windows Photos app can combine them into a single PDF without any extra software.

Best for: Combining JPG or PNG images into one PDF — not for merging existing PDF files. Windows 10 / 11

1
Select all your images in File Explorer

Hold Ctrl and click each image to select multiple files, or press Ctrl + A to select all images in a folder.

2
Right-click and choose Print

Right-click your selected images → Print. Windows opens the Print Pictures dialog.

3
Select Microsoft Print to PDF

Choose Microsoft Print to PDF from the printer list. Set layout to "Full page photo" for best quality.

4
Click Print and save

Click Print, choose where to save, and all your images combine into one PDF automatically.

💡 Pro tip: Need to convert images to PDF and then combine with an existing PDF? Use our Image to PDF tool first, then merge the result with your other PDFs using Method 1.
4

PowerShell — For Power Users and Automation

Windows PowerShell — built into every Windows 10 and Windows 11 PC — can merge PDFs using free third-party modules. This method is ideal if you merge PDFs regularly and want a repeatable, scriptable solution that works completely offline.

Best for: IT professionals, developers, or anyone who regularly merges batches of PDFs and wants to automate the process. Windows 10 / 11

Step-by-step instructions

1
Open PowerShell as Administrator

Press Win + X → click Windows PowerShell (Admin) or Terminal (Admin) on Windows 11.

2
Install the PdfSharpCore module

Run this command to install a free PDF library from the PowerShell Gallery:

Install-Module -Name PdfSharpCore -Scope CurrentUser -Force
3
Run the merge script

Replace the file paths and output name with your actual files:

# Define your PDFs to merge (in order) $files = @( "C:\Users\YourName\Documents\file1.pdf", "C:\Users\YourName\Documents\file2.pdf", "C:\Users\YourName\Documents\file3.pdf" ) # Output file path $output = "C:\Users\YourName\Documents\merged.pdf" # Merge using PdfSharpCore Import-Module PdfSharpCore $outputDoc = [PdfSharpCore.Pdf.PdfDocument]::new() foreach ($file in $files) { $doc = [PdfSharpCore.Pdf.IO.PdfReader]::Open($file, [PdfSharpCore.Pdf.IO.PdfDocumentOpenMode]::Import) foreach ($page in $doc.Pages) { $outputDoc.AddPage($page) } } $outputDoc.Save($output) Write-Host "✅ Merged PDF saved to $output"
💡 Save it as a script: Paste the code into Notepad, save as merge-pdfs.ps1, and run it anytime. Edit the $files array to change which PDFs to combine.
