Tesseract OCR Installation Guide for Windows

​

Step 1: Download

• Visit the https://github.com/UB-Mannheim/tesseract/wiki

• Navigate to the latest installer for Windows (tesseract-ocr-w64-setup-5.3.3.20231005.exe ).
   

Step 2: Installation

• Run the downloaded installer.

• Follow the installation prompts. It's recommended to select the option to add Tesseract to your system PATH during installation.
   

Step 3: Verify Installation

• Open Command Prompt and type tesseract -v to verify the installation. You should see the version number of Tesseract if it was installed correctly.
   

Step 4: Set Up System Path (if not set during installation)

• Right-click 'This PC' or 'Computer' on the desktop or in File Explorer.

• Click 'Properties', then click 'Advanced system settings'.

• In the System Properties window, click 'Environment Variables'.

• Under System Variables, scroll to find 'Path' and select it, then click 'Edit'.

• If Tesseract's installation path is not present, click 'New' and add the Tesseract OCR path (e.g., C:\Program Files\Tesseract-OCR).

• Click 'OK' to close all dialogs.
   

Step 5: Test Tesseract

• In Command Prompt, navigate to a directory containing an image file.

• Run a test command: tesseract image.png output -l eng.

• If Tesseract OCR is working, it will create a text file named output.txt with the recognized text.
   

Additional Notes

• For specific language support, you may need to download the appropriate language data files from the Tesseract OCR repository and place them into the 'tessdata' directory within the Tesseract installation folder.

Tesseract OCR Installation Guide for macOS
 

Step 1: Download

• Open Terminal.

• Install Homebrew if it's not already installed by running CLI
  
  /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)".
   

Step 2: Installation

Step 3: Verify Installation

• Confirm the installation by typing tesseract -v in Terminal. You should see Tesseract's version information.
   

Step 4: Set Up System Path

• Normally, Homebrew takes care of adding Tesseract to the system path. However, if you encounter issues, ensure that the path to Homebrew's binary directory is in your PATH environment variable.
   

Step 5: Test Tesseract

• Navigate to a folder with an image file in Terminal.

• Test OCR functionality: tesseract image.png output -l eng.

• Tesseract should create an output.txt file with the OCR results.
   

Additional Notes

• To install language data or other Tesseract utilities, use Homebrew to install them (e.g., brew install tesseract-lang).

• You can install specific language data files manually by downloading them from the Tesseract OCR GitHub repository and placing them in the appropriate directory (typically /usr/local/share/tessdata).
