よくある質問

What images work best?

ハイ-contrast images with clear subjects work best. Portraits, logos, and silhouettes produce the most recognizable ASCII art.

What does color mode do?

Color mode maps each pixel's color to the corresponding ASCII character using colored HTML spans. Monochrome uses only brightness to select characters.

How many characters wide should I set it?

80-120 characters works well for most images. Wider values (150+) capture more detail but need a larger screen or smaller font to display properly.
