Oh yeah I just remembered that a few months back on Fedi, someone asked (https://critter.cafe/@swiftyshq/115873473992788069) if there was a tool that would convert pixel art to ASCII art with specific mappings of colors to symbols. I didn't know of any such tool, but I thought it would be fun to implement, and so I did. You can access it through here (https://racc.at/pixelly).
A video of it working here:

I didn't spend much time making it pretty because I wanted to make it quickly... and then when I was done there was not much motivation to work on it any longer, lol.
It's also on my git forge here (https://git.racc.at/kett/pixelly), but it's literally just an HTML file and a JS file which you can see right from your browser.
