I made Riplet, a free and safe YouTube to MP3/MP4 converter that works on both desktop and mobile.

Since most converters blast you full of ads before even letting you download and then still some don't even download it correctly, I decided to create this tool.
It is completely free to use and I use donations to cover the server costs.

I’d appreciate any feedback! Especially if you run into issues:
