Is my image uploaded?

No. The browser decodes, samples, renders, and exports your image locally. The tool has no upload endpoint.

How does the character matching work?

Each source cell and every glyph are measured with the same six staggered circular luminance samples. The closest normalized six-value shape wins.

JPEG, PNG, and WebP images up to 20 MB work in modern browsers.

Every set has a different library of measured shapes and densities, so the nearest match for a source cell can change.

Turn an image into shape-matched ASCII art. The six-sample matcher and PNG export run entirely in this browser tab.
