How It Works

Step 1: User Input

Step 2: Fetch Video Data

  • The application uses the pytube library to fetch video details such as:
    • Video title
    • Thumbnail
    • Available resolutions and formats

Step 3: Download Options

  • Once video data is fetched, users can choose:
    • Resolution (e.g., 1080p, 720p).
    • Format (e.g., MP4 for video, MP3 for audio).

Step 4: File Download

  • Upon selecting the desired format, the file is downloaded to the user’s local system.

Technology Stack

  • Backend: Python (Django Framework)
  • Frontend: HTML, CSS, Bootstrap (for responsive design)
  • Database: SQLite (for user download logs, optional)
  • YouTube API: Pytube library for processing video content

      python manage.py migrate  
      
    • Start the Django development server:
      python manage.py runserver
