Information
How This Site Works
This web application allows you to download audio/video from YouTube, SoundCloud or other videos/tracks or playlists. You simply paste the URL, choose your desired format (MP3, M4A, Opus or MP4), and the server-side script processes your request.
The backend uses the powerful yt-dlp library to fetch content information and extract the audio/video stream. If MP3, M4A, Opus or MP4 format is selected, ffmpeg is used for conversion and to embed metadata.
The downloaded file is temporarily stored on the server and then made available for you to download directly through your browser. After the download is served to you, the file is automatically deleted from the server to save space and ensure privacy.
Key Libraries & Technologies Used
- Flask: A micro web framework for Python, used to build the backend API.
- yt-dlp: A command-line program to download videos/audio from YouTube, SoundCloud and many other sites. It's a fork of youtube-dl with additional features and fixes.
- FFmpeg: A complete, cross-platform solution to record, convert and stream audio and video. Used here for format conversion (to MP3/M4A/Opus/MP4) and metadata embedding.
- Tailwind CSS: A utility-first CSS framework for rapidly building custom user interfaces.
- JavaScript: Used for frontend interactivity, language switching, animations, and communication with the backend API.
Python Backend Code
The core backend logic is written in Python using the Flask framework. The Python script (typically named app.py) handles API requests, interacts with yt-dlp and ffmpeg, manages temporary file storage, and serves the files. This code runs on the server and is not directly visible here, but it ensures the functionality of the downloader.
