How does the image to ASCII conversion work?

The image is drawn onto a small canvas, pixel brightness values are sampled, and each pixel is mapped to an ASCII character — darker pixels get dense characters like '@' and '#', lighter pixels get sparse ones like '.' and ' '.

Can I adjust the output resolution?

Yes. Use the width slider to control how many characters wide the ASCII art is. Higher values produce more detail but a larger output.

How do I save the ASCII art?

Click 'Copy' to copy the text to your clipboard, or 'Download TXT' to save it as a plain text file.

How It Works

The image is scaled down and each pixel's brightness is mapped to an ASCII character. Dark pixels use dense characters (@, #) while bright pixels use sparse ones (., space).

Character Density Scale

Dense → @#%=+*:-. (darkest to lightest)
Best results with high-contrast images and clear subjects
Use a monospace font when pasting in editors for correct alignment
