This page holds small browser-side utilities. The tool surface and the blog explanation stay separate: this page is for using, previewing, and downloading results, while the blog post explains the implementation and its limits.
The current converter does not upload images to the server. Conversion runs locally in this browser, and the generated preview and download link expire after 30 minutes.
Image to truecolor Unicode quadrant ANSI
Drop an image and the browser will resample it to a terminal grid, then encode each cell with Unicode quadrant blocks and 24-bit ANSI foreground/background colors.

After downloading, run it in a truecolor-capable terminal: cat filename.ans
