What is the ASCII Art Generator?

The ASCII Art Generator is a creative client-side utility designed to convert local images and plain text into retro text-based graphics. By mapping pixel values to monospaced keyboard characters, the tool generates stylized monochrome or colored text representations of your graphics.

This generator processes pixel values locally using browser canvas elements. Because no data or images are sent to external servers, your photos, logos, and custom text banners are kept completely confidential.

How to Use the ASCII Art Generator

  1. Select Your Mode: Choose between "Image" mode (to convert photos) or "Text" mode (to generate styled word banners).
  2. Upload or Key-In Data:
    • In Image Mode: Drag and drop your image into the uploader area, or click inside it to select a file from your system.
    • In Text Mode: Type your word or phrase into the input box and select your banner font style.
  3. Adjust Art Settings: Calibrate the output width slider, character sets, contrast levels, and choose whether to invert colors or enable colored mode.
  4. Export Your Art: Click "Copy ASCII" to copy the text to your clipboard, or "Download Text" to save the result as a .txt file.

Frequently Asked Questions

ASCII art relies on monospaced fonts (like Courier, Consolas, or Fira Code) to align characters correctly. If you paste it into an editor or platform with variable-width fonts, the spacing will break. Additionally, wrapping text settings must be disabled.

No. 99tool.in processes all canvas pixel extraction and character assignments locally on your computer. Your graphics are never shared, uploaded, or cached.

The parser measures the brightness (luminosity) of grouped pixels. Darker areas are replaced with dense characters (like @ or #), while brighter areas are replaced with lighter symbols (like . or blank spaces).

Adjust the "Width" slider in the sidebar to scale the character grid down. A width of 80 characters is standard for terminal displays, while larger values work well for full-screen files.

Yes. By enabling "Color Mode", the tool wraps characters in HTML <span> tags with inline colors. Keep in mind that copy-pasting raw text outputs to plain .txt files will lose these colors.
