How to Make a PDF Text-Searchable with OCR on Mac
Question details
The user wants to apply Optical Character Recognition (OCR) to a scanned PDF on a Mac using Adobe software to make the text searchable.
- Product
- Adobe Acrobat
- Device & OS
- macOS
- Scenario
- Working with scanned PDF documents that need to be searchable and selectable.
- Observed behavior
- The PDF currently contains scanned images of text, preventing the user from searching, selecting, or copying the content.
Ensure you have Adobe Acrobat Pro or a compatible Adobe application installed on your Mac, as the free Adobe Acrobat Reader does not include OCR capabilities. Also, check that your scanned PDF is clear and legible for the best text recognition results.
Use the Scan & OCR Tool in Adobe Acrobat Pro
Apply Adobe Acrobat's built-in OCR feature to convert scanned images into searchable and editable text.
Adobe Acrobat Pro includes a dedicated Scan & OCR tool that can analyze the images in your PDF and convert them into selectable text. The exact interface may vary slightly depending on your specific version of Acrobat.
Launch Adobe Acrobat Pro on your Mac and open the scanned PDF document you want to make searchable.
Navigate to the right pane and click on 'Scan & OCR'. If you do not see it in the quick menu, click on the 'Tools' tab at the top of the window and select 'Scan & OCR' from the list of available tools.
In the secondary toolbar that appears at the top, click on 'Recognize Text' and choose 'In This File' from the dropdown menu.
Click the 'Settings' gear icon to confirm your document language and choose your preferred output style, such as 'Searchable Image'. Finally, click the 'Recognize Text' button to process the document.

Frequently Asked Questions
Why is the 'Recognize Text' option missing in my Adobe software?
If you are using the free Adobe Acrobat Reader, the OCR feature is not available. You need a paid subscription to Adobe Acrobat Standard or Pro to access the Scan & OCR tools.
How can I check if my PDF is already text-searchable on a Mac?
Open the PDF and press Command + F to open the search bar. Type a word you can clearly see on the page. If the word is highlighted and can be selected with your cursor, the document is already searchable. If not, it is a scanned image requiring OCR.
Does OCR work on handwritten PDF documents?
OCR technology is primarily designed for printed text. While modern OCR engines can recognize some very clear and standardized handwriting, the accuracy drops significantly compared to standard typed fonts.
Can I batch process multiple PDFs with OCR on a Mac?
Yes, in Adobe Acrobat Pro, you can use the 'Action Wizard' tool to create a custom action that applies OCR to multiple files or an entire folder of PDFs at once.
