How does ASCII art conversion work?

The image is drawn to a canvas, pixels are sampled, and brightness values are mapped to ASCII characters from lightest (space) to darkest (@).

Density controls how many characters are used. Higher density means more detail but wider output.

No. Everything runs in your browser using Canvas API. Your file never leaves your device.
