Mii Maker - A tool to create, pose, and render pictures/animations of Mii characters.
Pixel Converter - Converts images into pixel art. Customizable with different resolutions and color palettes.
Soundtrap - A relatively simple online DAW. You won't make a symphony with it but it's easy to use and offers real-time online collaboration.

FugiTech - A website to easily create simple PNGtubers to use with Discord.
