ASCII Art Generator

• Text banners (FIGlet style) — convert words into stylized lettering. Most common.
• Image-to-ASCII — convert photos to characters where each character's "darkness" approximates the local pixel brightness. Glance-readable from a distance; up close, it is just text.
• Line drawings / box-drawing — using Unicode box characters (┌─┐ │ └─┘) for diagrams in terminals.
• Animated ASCII — replaced by emoji and Unicode for most uses. Some retro IRC and BBS communities still produce ASCII animations.
• Hand-drawn ASCII — historically created character-by-character. The art form is mostly retro nostalgia in 2026.

• CLI tool banners — when your CLI launches, a stylized name in the first lines of output gives identity in long logs. cowsay, figlet, neofetch all exemplify this.
• README badges in pure-text — for projects published on platforms that strip images, a stylized banner is the only way to get visual emphasis.
• IRC and BBS communities — ASCII art is part of the culture; preserved as nostalgia for many active communities.
• Email signatures in plain-text — designers can encode brand mark as ASCII for emails sent to clients on legacy systems.
• Terminal-only documentation — man pages, vim help files, terminal-based tutorials use boxed text and ASCII diagrams.
• Easter eggs — `git checkout master && cowsay "moo"` is still funny.

Convert a photo to ASCII by mapping pixel brightness to character "darkness": @ (dark), # (medium-dark), $ (medium), % (medium-light), (light), (lightest). Different "ramps" of characters produce different aesthetics. Aspect ratio matters: monospace characters are taller than wide, so the source image needs to be scaled vertically before mapping.

• Best for high-contrast portraits — silhouettes, line drawings, ink art.
• Bad for low-contrast photographs — landscapes with gradients become uniform blocks.
• Color version uses ANSI escape codes — works in modern terminals; renders as plain text in non-color-aware contexts.
• For very small output, dither (Floyd-Steinberg) the brightness mapping for better perceived detail.

• You are launching a CLI tool and want a banner that appears on first run.
• You are writing a README for a project and want a stylized header in pure text.
• You are setting up a server with a custom MOTD (message of the day) and want a stylized banner.
• You are participating in a retro / nostalgia community and want to author ASCII art correctly.

• It will not produce useful art for general decoration. ASCII art is niche; for visual decoration, use images.
• It will not preserve fidelity when image-to-ASCII converting complex photos. The character ramp is a 6-10-step grayscale; expect aggressive quantization.
• It will not survive copy-paste through HTML emails or rich-text editors. ASCII art needs monospace rendering; rich text in proportional fonts breaks the alignment.
