YouTube Video Downloader Using Python and Django

Available Features

• Video Download Options
  The system provides multiple choices for downloading YouTube content. Users can download videos in different resolutions such as 1080p, 720p, and 360p, depending on their preference or internet speed. In addition, there is an option to download only the audio in MP3 format, which is perfect for users who just want songs, podcasts, or speeches without video.

• User-Friendly Interface
  The project comes with a clean and responsive frontend built using Django templates. Users simply need to paste the YouTube URL into the input box and select their desired download option. If an invalid or unsupported link is entered, the system instantly shows an error message, making it reliable and easy to use for everyone.

• Real-Time Processing
  Once a YouTube link is submitted, the application quickly fetches all the important details like the video title, thumbnail, and duration. These details are displayed on the page, and the user is provided with download links for various available formats. This real-time update ensures smooth and interactive usage.

• Secure and Efficient
  The system validates YouTube URLs before processing to make sure only correct and safe links are handled. All the backend logic runs through Django views, ensuring that the application performs downloads efficiently without interruptions. This makes the project both secure and dependable for practical use.

How It Works

Step 1: User Input

• Users input a valid YouTube video URL into a search box on the homepage.

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)
