Convert an Image to ASCII Art

No. The image is decoded and converted entirely in your browser using a canvas. It never leaves your device, so private images stay private.

The image is sampled down to a grid of cells sized to your chosen width. Each cell's brightness (a weighted average of its red, green, and blue) is mapped to a character, from a light glyph for bright areas to a dark glyph for dark areas.

Monospace characters are about twice as tall as they are wide, so the tool uses roughly half as many rows as columns. That keeps the proportions of your image right when it is rendered as text.

By default the art is built for dark glyphs on a light background, like black text on white paper. Turn on invert when you will display it as light text on a dark background, such as a terminal, so light and dark read the right way round.

Standard is a short, clean ramp that works for most images. Detailed uses around 70 characters for smoother gradients and bigger output. Blocks uses shading characters for a denser, more solid look. High-contrast images give the clearest results.
