Open your scanned PDF document in Adobe Acrobat.

In the Scan & OCR pane, click Recognize Text.
Choose In This File to apply OCR to the open document.
Click Recognize Text to start the OCR process.
Save the PDF to retain the searchable text layer.
Best practiceFor best OCR accuracy, scan your documents at 300 dpi and avoid extreme brightness settings.
After OCR, you can search, select, and copy text from your scanned PDF as if it were a normal document.
This runs in the Acrobat app - there is no separate API for this task.
Recognizing text in a scanned document makes the text searchable and selectable. Without it, your scan is just a picture, and you can't copy text or find specific words. This process adds a hidden text layer so you can interact with the document's content.
Text recognition might struggle with blurry scanned notes. OCR works by identifying shapes as characters, and blurriness makes these shapes hard to distinguish. For better results, try to rescan your notes at a higher resolution and ensure they are clear and in focus before processing them with Scan & OCR.
Acrobat shows this message because the 'Recognize Text' feature is designed for image-only pages. If a page already has real, selectable text on it (even if it looks like an image), Acrobat won't try to recognize text again. It's a way to prevent errors and ensure you only apply OCR where it's needed.
