About this tool
Turn any image into ASCII art entirely in your browser — the picture is sampled on a canvas and mapped to characters, and nothing is uploaded.
Frequently asked questions
How does it turn pixels into characters?
The image is drawn to a small canvas, the brightness of each cell is measured, and that value is mapped onto a ramp of characters from light to dark.
Is my image sent anywhere?
No. The image is read locally with FileReader and processed on a canvas in your browser; nothing leaves your device.
