YouTo4

YouTo4 is an open-source YouTube mp4/mp3 converter It is built using html so you will have to run it in your browser but it requires very little setup.

I will be adding an mp4 addition to this soon enough. I just needed to download youtube video mp3 for music samples and I hated how all other websites took too long or displayed stupid ads, so I made my own. This is my first time doing a public repository on GitHub and my first time doing instructions so sorry if they suck. I'm also not sure if the mac/brew instructions work please someone let me know if they don't (As im already guessing they don't)

How to run:

🧱 Prerequisites:

Make sure you have installed:

- Node.js (v16+ recommended)

- yt-dlp

For brew:

    
brew install yt-dlp
    
  

Standalone download:

1. Go to the yt-dlp GitHub Releases page.

2. Download: yt-dlp.exe

3. Move it to a permanent folder like:

  
C:\yt-dlp\
  
  

4. Add that folder to your System PATH:

Press Win + R, type sysdm.cpl, go to Advanced > Environment Variables.

Under System variables, find Path, click Edit, then New, and add:

  
C:\yt-dlp\ (or whatever you named your file)
  
  

Once finished installing yt-dlp run:

    
yt-dlp --version
    
  

If it shows a version number, you can move on.
