How do I make scanned notes searchable in Adobe Acrobat?

Open your scanned PDF in Acrobat. Go to All tools > Scan & OCR. Choose 'In this file' and set the correct language. Click 'Recognize Text' and wait for it to finish. Now you can search for words in your notes.

If my scan is blurry or low quality, will OCR still work?

OCR works best with clear and sharp scans. Blurry or low-quality scans might cause mistakes or miss some text. Try to scan at 300 dpi for better results.

Now you can search for words in your notes.

OCR stands for Optical Character Recognition. It is a technology that reads text from images, such as scanned pages, and turns it into real text that you can search, copy, or edit. This is important for scanned notes because, without OCR, the notes are just pictures, and you cannot look for specific words or phrases. With OCR, you save time and can find information quickly in your documents.

OCR works best with clear and sharp scans.
Blurry or low-quality scans might cause mistakes or miss some text.
Try to scan at 300 dpi for better results.

Acrobat shows this message because your PDF already has real text that can be selected or copied. OCR is only for pages that are pure images, like scanned papers. If your file is not image-only, OCR will not run. Check your PDF to make sure it is just an image before using OCR.
