Image Analysis

Your image is loaded into an HTML5 Canvas element to extract pixel data for processing.

Brightness Mapping

Each pixel's brightness is calculated using the ITU-R BT.601 formula for accurate luminance.

Character Selection

Brightness values are mapped to characters from the selected density string. Darker areas use denser characters like @ and #, while lighter areas use sparse characters like . and space.

Edge Detection

The optional Sobel filter detects edges by calculating intensity gradients, creating a line-art style output perfect for logos and drawings.

Color Preservation

In color mode, each character inherits the original pixel's color, creating vibrant ASCII art that maintains the image's color palette.

Frequently Asked Questions

High-contrast images with clear subjects work best. Portraits, logos, and simple graphics produce excellent results. For photos, try enabling edge detection for a cleaner look.
