How it works

  1. 01Find the video you want on YouTube.
  2. 02Copy its URL from the address bar, or right click the video and copy the link.
  3. 03Paste the URL into the field above and press upload.
  4. 04When the video finishes uploading, hit download and your MP3 is ready.

This is a simple tool for taking any YouTube video you find and turning that video's audio into a downloadable MP3 file. It uses the youtube-dl package to pull the important details out of a video, such as the title and thumbnail, and returns them to the browser so you can confirm you picked the right one before downloading.

The video details are stored in a Google Cloud NoSQL database alongside a download URL, and the MP3 itself is uploaded to Firebase Cloud Storage at request time. The download button then streams the file straight from that cloud URL.
