The tool works by loading your image onto a hidden HTML canvas. It resizes the image down to your specified width, while intelligently calculating the height to maintain the original aspect ratio and account for the fact that text characters are taller than they are wide. It then goes through each pixel, calculates its brightness, and maps that brightness to a character from the selected set. Darker pixels get denser characters (like '@'), and lighter pixels get sparser characters (like '.').

The generator analyzes each pixel region of your uploaded image and assigns a character based on brightness. Characters with more visual weight (like @, #, and %) represent darker areas, while lighter characters (like .:, and spaces) represent brighter areas. When the characters are combined together in a monospaced font, they recreate the shape and shading of the original image. Adjusting the output width changes how many characters are used per row, which directly affects the level of visible detail.

Drag and drop an image from your computer into the upload area, or click the area to browse for a file. · The generator automatically converts the image into ASCII characters below. · Adjust the output width field if you need more or less detail. · Click the copy button or download the result as a text file. · Paste the ASCII art into your destination, making sure it uses a monospaced font for proper alignment.
