Treasure Island Map ASCII Art
Three men gather around a paper map in Louis Rhead's 1915 illustration for Treasure Island
Three figures lean over the map at a table; the faces and hands form the strongest shapes against the crosshatched room. At 100 columns, small map markings disappear but the group remains clear; keep the image at full height to preserve the table and figures. Illustration: Louis Rhead, 1915; ASCII conversion by this site.
Built Standard preview: 100 columns by 71 rows. Each result card lists its recipe. Select the text below to copy it without JavaScript.

Checking destination fit...
README and chat presets use printable ASCII. Unicode blocks and edge lines need matching font support; emoji can occupy different widths on another device. PNG keeps this browser's rendering, not another app's emoji style.
Sharing ASCII art in Telegram? Check monospace formatting and wrapping before sending. Ordinary chat formatting and Bot API HTML are different.
Edge detection
Edge Detection Only: 100 columns; rows = max(1, round(columns × source height / source width × 0.55)).
Edge Intensity: 1. Uses directional Unicode lines, not the selected character ramp.
Brightness 100%, contrast 100%, saturation 100%, hue 0, sepia 0%, inversion off. Dithering does not apply to this mode.
Open this recipe in the editor to keep this source, mode and settings. Browser resampling and fonts can differ from the built preview. Copy/TXT retain text; PNG uses black text on white at 12 px monospace, at least 1.2 line spacing and 20 px padding, independent of screen theme.
Character Optimization matches local glyph shapes in 4x8 cells at 8 px monospace. Compare texture with Standard; it is not a universal quality improvement, and your display font does not change the matching font.
Character Optimization
Character Optimization: 100 columns; rows = max(1, round(columns × source height / source width × 0.55)).
Character ramp: @%#*+=-:. (including a final space).

Mosaic comparisons use 15 symbol columns, not the 100 columns of the character modes. The detailed recipe increases contrast to 150%; choose Coarse mosaic in the editor for the original five-column style.
Detailed emoji mosaic
Emoji Mosaic: sampling width 60, Emoji Size 4, squares set, transparent-cell symbol "⬜". Final columns = ceil(width / Emoji Size); rows depend on source aspect ratio.
Brightness 100%, contrast 150%, saturation 100%, hue 0, sepia 0%, inversion off. Dithering does not apply to this mode.
