Convert image luminance values into character-based ASCII art directly in the browser, with transparent pixels composited against a light background.
The image brightness map was converted into lines of printable ASCII characters.
Upload an image to generate ASCII art.
The browser downsizes the image, composites transparent pixels against white, measures the luminance of each sampled pixel, and maps darker and lighter values to different characters.
Character width and the selected charset change how much detail the final ASCII art can preserve.
Text characters are taller than they are wide, so the tool compensates with a height ratio, but fonts still affect the final look.
Yes. The result is plain text, so it works well in monospaced contexts.
Only indirectly. The tool converts the image to brightness values before mapping them to characters.
High-contrast images and portraits with clear shapes usually translate well into ASCII art.
ASCII art conversion is a text-generation workflow, not an image-preserving one, so fine details will always be simplified.
Changing the width and charset is often enough to get noticeably better results from the same image.
Monospaced display is important for the output to keep its intended shape.
