Frequently Asked Questions
How does the Image to ASCII Converter work?
Your image is decoded to raw RGBA pixel data. For each pixel, the tool calculates perceived brightness using the luminance formula (0.299R + 0.587G + 0.114B) and maps that value to a character from a density ramp -- dense characters like @ and # for dark areas, sparse characters like dots and spaces for light areas. The standard ramp uses 70 distinct brightness levels for fine detail.
Can I adjust the output size?
Yes. Set the width in characters. Wider output produces more detail but takes up more space. A width of 80-120 characters is typically a good balance for most images.
What can I do with ASCII art?
Copy it into code comments, README files, terminal output, text-based messaging, email signatures, or social media posts. ASCII art displays correctly in any monospace font environment.
