# Built-In Style Presets for ASCII Art

> ASCII ships with eight style presets — Classic, Matrix, Newspaper, CRT Terminal, Neon, Game Boy, Blueprint, and Xerox — each a complete settings snapshot.

The tool ships with eight built-in style presets that cover a wide range of aesthetics — from clean monochrome terminal output to glowing neon, vintage Game Boy palettes, and high-contrast blueprint hatching. Each preset is a complete configuration snapshot that sets the character set, cell size, color mode, contrast, and any post-processing effects all at once.

## Applying a preset

<Steps>
  <Step title="Open the Preset dropdown">
    At the top of the sidebar, find the **Preset** dropdown (labelled with the placeholder text "choose…") and click it to expand the list of built-in options.
  </Step>

  <Step title="Select a preset name">
    Choose one of the eight preset names: Classic, Matrix, Newspaper, CRT Terminal, Neon, Game Boy, Blueprint, or Xerox.
  </Step>

  <Step title="Click Apply">
    Click the **Apply** button next to the dropdown. All controls in the sidebar update immediately and the canvas re-renders with the new settings.
  </Step>
</Steps>

<Tip>
  Presets are a starting point. After clicking Apply you can adjust any individual control — cell size, contrast, bloom amount, and so on — without saving over the built-in preset.
</Tip>
