Video Downloader is a small desktop app for saving videos from a URL, built with Python and a CustomTkinter interface. The idea is that you should never have to type a terminal command: you paste a link, pick a format, and the app does the rest. When you paste a URL and click Fetch Info, the app shows you the video's title, duration, and thumbnail before anything downloads, so you can confirm it found the right video. You then choose one of three formats: the full video at the best available quality, audio only saved as an MP3, or the video with no audio track at all. You also pick which folder the file should land in. While a download runs, a progress bar shows the percentage complete along with download speed and an estimated time remaining. If you change your mind partway through, a Cancel button stops the download cleanly instead of leaving a broken, half finished file sitting in your folder. If something goes wrong, the app shows a plain readable error message rather than a wall of Python code, which matters for anyone who is not a programmer. Under the hood, the app relies on yt-dlp to do the actual video fetching, so it inherits support for whatever sites yt-dlp can handle. Downloads run on a background thread, which is why the window keeps responding instead of freezing while a big video comes down. To run it yourself you need Python 3.9 or newer, then install the dependencies (CustomTkinter for the interface, yt-dlp for downloading, and Pillow for handling thumbnail images) and start the program from the command line once. After that first launch, everything happens through the window: paste a link, fetch its info, choose a format and folder, and press Download.
