When you need to display eye-catching text in environments that do not support rich text, ASCII art can create a strong visual impact using basic character combinations. This tool converts your input text into a 2D pattern made of letters, numbers, and symbols. It works by simulating grayscale gradients through specific character densities, typically with a height of 5 to 7 character units per line.
Why is my Chinese ASCII art misaligned?
Chinese characters are twice as wide as Western letters. When mixing inputs, we recommend using mostly English characters and using Chinese sparingly as accents.
What are the best use cases for ASCII art?
Code comment headers (used by 43% of users), command-line interface (CLI) welcome messages, forum signatures, and other text-based environments that need lightweight visual elements.
Inputs exceeding 50 characters may result in patterns that are too wide. For mobile display, we recommend testing the preview first. Please do not convert sensitive content.
When using the output in editors like VS Code, we recommend pairing it with a monospaced font like Monaco. Typical conversion example: Entering "OK" and selecting the Doom font will generate a bold effect with diagonal shading, a style that is especially suitable for status indicators in shell scripts.
