Nice work. Can we know what algo or mapping logic you using to do this?

Thanks! Essentially it splits the image into emoji-sized parts and finds the dominant color of that part using color-thief.js. It then converts the RGB value into the LAB color space and finds the closest emoji match using the CIE76 color difference algorithm. The emojis are also handpicked to ensure no small ones like the plane and car get in.

hahaha :) cool stuff! Feedback: smaller emojis would be a bit better. Would it make sense to add 'download' jpg after conversion?

Nice job!

I tried copying the emojis and sending via iMessage. Didn't work :( didn't work on FB either. How do you use it?

Fun, but you should really make it render with real emojis so people can copy/paste the results.
