Extract Text from Images with OCR

Our OCR tool uses Tesseract.js to recognize text in photos, scanned documents, and screenshots. The recognition engine runs directly in your browser, so your images are never uploaded.

How to Extract Text from an Image

  1. Upload: Select a photo or screenshot containing text.
  2. Choose Language: Select the language of the text in the image for better accuracy.
  3. Extract: Click Extract Text. The OCR engine downloads on first use, then recognizes text in seconds.
