Scan as an Image and Convert via Adobe Acrobat

Since the free Adobe Reader cannot create PDFs, you must scan the document using your system's default scanner software and then use a premium Adobe tool to convert the image.

The free version of Adobe Acrobat Reader is designed strictly for viewing and annotating PDFs. It does not contain the functionality to communicate with a scanner or generate new PDF files from scanned inputs.

To achieve your goal using Adobe products, you will need either an active subscription to Adobe PDF Pack or the full Adobe Acrobat software.

1
Scan the document to your desktop

Use your computer's built-in scanning utility (such as Windows Fax and Scan or Apple Image Capture) to scan the physical document. Save the scanned file to your desktop as a standard image format, like JPEG or PNG.

2
Open Adobe Acrobat or PDF Pack

Launch your paid Adobe Acrobat application on your computer, or log into the Adobe Acrobat online service if you are using the Adobe PDF Pack.

3
Use the Create PDF tool

Navigate to the Tools menu and click on 'Create PDF'. If you are using Acrobat Pro, you can also select 'Scanner' as your source to scan directly without saving as an image first.

4
Convert and save

Select the scanned image file you saved on your desktop. Follow the on-screen prompts to convert the image into a PDF format, and then click 'File' > 'Save As' to store the final document.

Alternative to Scanning: If you already have a digital PDF that just needs a signature, you do not need to print and scan it. Use the 'Fill & Sign' feature in Adobe Reader to digitally apply your signature for free.

Frequently Asked Questions

Can I scan directly from my printer into the free Adobe Reader?

No, the free Adobe Acrobat Reader does not support creating PDFs directly from a scanner. You can only use it to view, print, and annotate existing PDF files.

Do I have to pay to convert a scanned document to a PDF?

If you are strictly using the Adobe ecosystem, yes. Creating a PDF from a scan or image file requires a paid subscription to Adobe Acrobat or Adobe PDF Pack. However, alternative software like WPS Office offers features to convert images to PDF without an expensive subscription.

What image formats can be converted to PDF?

Most standard image formats created by scanners, including JPEG, PNG, BMP, and TIFF, can be easily recognized and converted into a PDF document using PDF converter tools.

How do I sign a document that is already in PDF format?

If your document is already a PDF, there is no need to print and scan it. You can use the 'Fill & Sign' tool available in both free Adobe Acrobat Reader and WPS Office to type, draw, or insert an image of your signature directly onto the digital file.
