1.5. Text Recognition (OCR)

Optical character recognition (OCR) is an intelligent text recognition technology that recognizes text in your scans and makes them searchable. Once a scan or an image goes through the OCR processing, it’s easy to read, select, and copy the contents to other apps. 

  • Prerequisites
  • Choose a language to recognize text 
  • Recognize, copy, and share the text
  • Disable the Automatic Text Recognition
  • Privacy
  • Troubleshooting


Improved OCR technology described in this article is available in Scanner Pro 8.0 or later. For those who previously bought Scanner Pro, this functionality is free. New customers can find the subscription info here.

Choose a language to recognize text 

Scanner Pro recognizes text in automatically preselected Latin-based languages by default. To switch to another language to process your scans, follow these steps:

  1. Open the Scanner Pro Settings and tap Text Recognition (OCR).
  2. Make sure the Automatic Text Recognition (OCR) toggle is enabled. 
  3. Disable the Latin based-languages toggle and choose one language from the list.
  4. Tap Save

Recognize, copy, and share text

  1. Open a scan in Scanner Pro and tap Text at the bottom toolbar.
  2. Choose the Document or the Text tab at the top. The Document tab contains your scan with a text layer upon it while the Text tab contains text extracted from the scan.
  3. If the language of the scan differs from the one which is usually used in the text of your scans, tap Language at the bottom toolbar and make sure to choose the right language: 
  • If the language of this scan is a Latin-based language, make sure that the Latin-based language toggle is enabled. 
  • If the language of the scan is not a Latin-based and differs from the one you had manually chosen in Settings, select a new language from the list and tap Reprocess. 

Then, select and copy the needed part of the text, tap Copy All at the bottom toolbar, or select Share to export the text layer to other apps. When finished working with the text, tap Done at the top right corner.

Disable the Automatic Text Recognition

The Automatic Text Recognition is enabled by default and this allows you to quickly recognize and search through the contents of your scans. To turn it off, open the Scanner Pro Settings > Text Recognition (OCR), and disable the Automatic Text Recognition (OCR) toggle. After that you’ll be asked whether to recognize text or not every time you tap Text at the bottom toolbar or try searching within the document.


Please note that Scanner Pro uses an on-device OCR model. That means that we don't upload the recognized text to any cloud storages and it is being safely stored on your device only. To learn how we treat your data to provide safety for your data, view our Privacy Policy. It can be found on our website or directly via Scanner Pro Settings > Privacy Policy.
