Run OCR to Make the PDF Editable in Acrobat

Before you can edit a scanned document, Acrobat must analyze the image and convert it into real text.
Open your scanned PDF in Adobe Acrobat. Go to the 'Tools' menu and select 'Scan & OCR' (or 'Recognize Text' in older versions).
Choose the correct language of the text in your document from the settings to ensure accurate character recognition.
Click 'Recognize Text' to initiate the OCR process. Wait for Acrobat to analyze the pages and convert the images to text.
Once the OCR process finishes, click on the 'Edit PDF' tool. You can now click on the recognized text to modify, delete, or add content.

Frequently Asked Questions
Why can't I edit text directly in my scanned PDF?
When you scan a physical document, the scanner captures the page as a flat image rather than individual text characters. To make it editable, you must use an OCR (Optical Character Recognition) tool to convert the image back into text.
Does Adobe Acrobat Reader have the OCR feature?
No, the free version of Adobe Acrobat Reader does not include OCR capabilities. You need a paid version like Adobe Acrobat Pro to use the Scan & OCR tools.
How can I improve OCR accuracy on my scanned PDFs?
Ensure your original scan is clear, straight, and has a high resolution (at least 300 DPI). Additionally, make sure you select the correct primary language in the OCR settings before running the recognition process.
