ASCII Art - Quick Cheat Sheet

Character set: Ordered from darkest to lightest. Put "dense" characters first (e.g., @) and airy ones last (e.g., space).
Cell size: Smaller cell width/height = higher resolution (more characters) but slower; larger cells = faster, chunkier output.
Brightness mapping: Each cell's pixels are averaged using luma (0.2126R + 0.7152G + 0.0722B) then mapped to a character index.
Fonts: Display and paste into a monospace font to preserve alignment.
Performance: Huge images may render slowly. If it lags, increase cell size.
Privacy: Images never leave your device; everything runs in your browser.
