Frequently Asked Questions
What makes some images convert better than others?
High-contrast images with clear outlines produce the best ASCII art. Complex photos with many similar tones may look muddy.
What is the difference between simple and detailed charsets?
Simple uses 10 characters (from @ to space). Detailed uses 70 characters for finer brightness gradations.
Why use invert mode?
The default works well for dark-on-light terminal output. Invert mode reverses the mapping — use it when the image has a dark background or you want light characters on a dark terminal.
