How it works
Upload an image and the tool sends it to a server-side converter that crops it to the selected aspect ratio, extracts grayscale brightness from each cell in a grid, and maps each value to a character from the selected character set — darker pixels become denser characters, lighter pixels become sparser ones. Click the ASCII preview to enter repositioning mode and drag to adjust the crop window when the aspect ratio clips the image.
