# How do I combine scanned pages into one PDF?

# How do I combine scanned pages into one PDF?

If an essay is more than one page, it’s necessary to upload it as a single PDF file. Both Windows and macOS have built-in tools that make this easy, and there are also free alternatives.

## On Windows
* **Windows Scan** can save each page as a PDF or image.  
* To combine pages into one PDF, you can use the free **Microsoft Print to PDF** option:  

1. Select all the scanned pages.  
2. Right-click and choose **Print**.  
3. In the Printer dropdown, select **Microsoft Print to PDF**.  
4. Save the output as a single file.

## On macOS
* The built-in **Preview** app lets you scan directly from most printers and also combine PDFs:  

1. Open the first scanned page in Preview.  
2. Go to **Edit > Insert > Page from File…** to add more pages.  
3. When all pages are added, choose **File > Export as PDF**.  

For more details, see Apple’s guide: [Scan a document or image in Preview on Mac](https://support.apple.com/en-ca/guide/preview/prvw28034/11.0/mac/26)

## Free alternatives
If you prefer, you can use free apps such as:  
* **Adobe Scan** (iOS/Android) – scans with your phone and creates multi-page PDFs automatically.  
* **Microsoft Lens** (iOS/Android) – also free, with auto-trimming and PDF export.  

Once you have one clean PDF file for the entire essay, you can upload it to EssayGrader as usual.
