Python Screenshot & Text Extractor

Two simple Python scripts that allow you to capture screenshots and extract text.

Overview

Screenshot Tool (screenshot.py)

Captures a Customizable Region of your screen instantly with a single key press.
Unlike most screenshot tools, you only need to set the capture region once. Then you can take as many screenshots as you want without reselecting.

Text Extraction Tool (extract_text.py)

Extracts text from your screenshots using OCR (Optical Character Recognition) via Tesseract.
This is best suited for screenshots that are all or mostly text. It handles batch processing, meaning that you don't need to extract one by one.

Why?

If you want to take multiple images of a set region without having to click and drag the screenshot area over and over again, this is for you.

If you want to get text from a screenshot of a video or a game, or text from a site that won't let you Ctrl +C, this is for you.

How To Use

Screenshot Tool

• Run: python screenshot.py
• Use the Following Key Presses:
  • 1 → Set top-left corner
  • 2 → Set bottom-right corner
  • Z → Capture screenshot
  • Esc → Quit program
• Automatically saves images with timestamps in a screenshots/ folder (can be changed)

Text Extraction Tool

• Run: python extract_text.py
• Extracts text from all images in a folder
• Uses preprocessing:
  • Grayscale conversion
  • Auto contrast
  • Denoising and sharpening
  • Adaptive thresholding
  • Upscaling for better OCR accuracy
• Saves each image’s extracted text as a separate .txt file in a text/ folder (can be changed)

Requirements

• Python 3.8+
• Dependencies:

  pip install pyautogui keyboard pillow pytesseract opencv-python numpy
  
    Tesseract OCR:
  
        Windows: Download installer
  
        macOS: brew install tesseract
  
        Linux (Debian/Ubuntu): sudo apt install tesseract-ocr
  

If you’re on Windows, update this line in extract_text.py if Tesseract isn’t in your PATH:

pytesseract.pytesseract.tesseract_cmd = r'C:\Program Files\Tesseract-OCR\tesseract.exe'
