The OCR Master window provides direct access to pre-processing settings, allowing you to adjust them while viewing the results immediately.

  • Image Upscaler

    • Increases the resolution of the captured image

    • Makes small or blurry text clearer and more recognizable

    • Useful for games with small font sizes
