For those wanting to explore automatically converting art pieces to 1-bit you can use 8Bit Photo Lab on iOS or Android. Select the black and white palette and choose resolution and dithering type.

Automatic conversion to 1-bit has been available since the 1980's. The trick is to do it artfully.
On macOS, there's a great piece of freeware called Retro Dither that does the job well: https://apps.apple.com/us/app/retro-dither-b-w-is-beautiful/...
