A pixel-perfect web-based MS Paint remake and more. Ah yes, good old Paint. Not the one with the ribbons or the new skeuomorphic one with the interface that can take up nearly half the screen. (And not the even newer Paint 3D.) Recreates every tool and menu of MS Paint, and even little-known features, to a high degree of fidelity. It supports themes, additional file types, and accessibility features like a Dwell Clicker and Speech Recognition. Claims to be mobile friendly.

You can create links that will open an image from the Web in JS Paint. Rudimentary multi-user collaboration support. It isn't seamless; actions by other users interrupt what you're doing, and visa versa. Sessions are not private, and you may lose your work at any time.

jsPaint can be installed as a Progressive Web App (PWA), although it doesn't work offline yet. Look for the install prompt in the address bar.
