How to Use the Image to ASCII Art Converter

Upload any image and convert it to ASCII art made from text characters. Adjust the width and brightness settings, then copy or download the result.

Settings

  • Width (characters) — Controls the number of characters per line (20-200). Higher values produce more detail but require a wider display.
  • Invert Brightness — Toggle to swap light and dark characters. Use this when your ASCII art will be displayed on a dark background.

Character Density

The tool maps pixel brightness to a set of ASCII characters from light (space, period) to dark (@, #, %). Darker pixels become denser characters, creating a recognizable image from plain text.

Frequently Asked Questions

What is ASCII art?

ASCII art is a graphic design technique that creates images using text characters from the ASCII standard. Each character represents a different shade of gray based on its visual density.

What width should I use?

For social media or messaging, 60-80 characters works well. For detailed images, try 120-150 characters. The preview adjusts font size to fit the display.

Can I use the ASCII art in my projects?

Yes. Copy the text output or download the .txt file. ASCII art works great in README files, terminal displays, code comments, and retro-style designs.

Why does my image look better inverted?

If you plan to display the ASCII art on a dark background (terminal, dark mode), enable "Invert brightness" so the character density matches correctly.

Is my image uploaded to a server?

No. All conversion happens locally in your browser using the Canvas API. Your image never leaves your device.
