Brightness chooses the character
Each reduced image cell is measured for perceived brightness. Dark and light values select characters with different visual weight.
Monochrome ASCII art uses one foreground color and lets character shape do all the visual work. Color ASCII adds a second signal: every output cell keeps a color sampled from the corresponding part of the image. A red subject remains red, a blue sky stays blue, and the character ramp still describes highlights, midtones and shadows.
The converter performs both steps locally with browser image and Canvas APIs. Microsoft Clarity measures general site interaction, but Pic to ASCII does not intentionally send your selected source image bytes to Clarity or to an application server.
The same reduced pixel grid determines both the character and its color, so changing width affects detail and output size together.

The same cell keeps its composited RGB color. The preview applies that color to the selected character instead of flattening everything to one foreground tone.
Plain text is easiest to paste but cannot carry color. The HTML download keeps each character color in a self-contained file without embedding your source image.
Clipboard text works in READMEs, terminals, chats and code blocks, but plain text formats do not define per-character RGB color. Use Copy plain text when the character silhouette matters most. Use Download HTML for a browser-ready artwork that preserves the preview colors and background.
