Best practiceFor best OCR accuracy, scan your documents at 300 dpi and ensure the images are clear before running OCR.
After OCR completes, you can search, copy, and highlight text in your previously scanned PDF.
This runs in the Acrobat app - there is no separate API for this task.
A searchable text layer is an invisible layer that Acrobat adds to your scanned document. It contains the text that OCR recognized from the image. This layer is important because it allows you to search for words within the document, copy text, and interact with the content as if it were a regular digital document, even though it started as an image.
No, if your scanned document already contains 'renderable text' (meaning it's not just an image but has actual text data), Acrobat's Scan & OCR feature will not work. It is designed only for pages that are purely images. If you try to run OCR on a document with existing text, you will likely see an error message. You should only use Scan & OCR on documents that are image-only PDFs.
Choosing the correct language is very important because OCR software uses language-specific rules and dictionaries to recognize words. If you select the wrong language, Acrobat might misinterpret characters or words, leading to many errors in the recognized text. This makes the document less searchable and less accurate, so always set the language to match the document's content.
| Action | What it does | Result |
|---|---|---|
| Scanning a document | Turns a physical paper into a digital image file (PDF). | An image-only PDF, where text cannot be searched or copied. |
| Recognizing text (OCR) | Analyzes the image of text in a PDF and converts it into actual, selectable text. | A searchable PDF with an invisible text layer, allowing search and copy functions. |
