What is ShareX OCR?
ShareX includes a built-in Optical Character Recognition (OCR) engine that can extract text from any image or screenshot. When you capture a region of your screen, ShareX can automatically recognize and copy the text to your clipboard.
How to Use OCR in ShareX
- Capture a screenshot containing text (use region capture for best results)
- After capture, go to After capture tasks and enable Recognize text (OCR)
- ShareX will process the image and copy the recognized text to your clipboard
- You can also use the OCR entry under Capture menu manually
Languages and Accuracy
ShareX supports multiple OCR languages through Tesseract. You can configure:
- Language selection in Task Settings → OCR tab
- Primary languages: English, Chinese, Japanese, Korean, German, French, Spanish, and 100+ more
- For best accuracy, ensure your screenshots are high-resolution with clear text
Common Use Cases
- Copying error messages for troubleshooting
- Extracting text from images when you can't select it normally
- Digitizing printed documents by taking a photo and running OCR
- Copying text from presentation slides or video frames
- Grabbing code snippets from tutorial videos or screenshots
Tips for Better Results
- Use region capture to isolate the text area — less background noise means better accuracy
- Higher resolution screenshots produce more accurate OCR results
- For multi-language documents, set OCR to the dominant language for best results
- Combine with After capture tasks to automate the OCR process
