What characters are supported?

Uppercase A-Z, digits 0-9, and space. Lowercase letters are automatically converted to uppercase before rendering, since the built-in font only defines uppercase glyphs.

What happens if I use punctuation or another unsupported character?

That character is rendered as a blank glyph (empty space) in the banner, and a note listing every unsupported character used is appended below the output so nothing fails silently.

How is this different from FIGlet-style ASCII art generators?

FIGlet supports dozens of downloadable third-party fonts with more elaborate letterforms. This tool uses a single small, original 5-row block font built specifically for this site, it's simpler and more limited by design, not a FIGlet-compatible renderer.

Is there a length limit?

Yes, input is capped at 20 characters, since each character expands into a 5-column-wide glyph and longer banners would become impractically wide to read on screen.

ASCII Art Generator - Text to Block-Letter Banner Art

Overview

Introduction

Turning a short word into big, eye-catching block-letter text is a classic terminal and README trick, useful for banners, headers, or just for fun.

This tool renders your input as large block letters using a simple built-in bitmap font, with every character drawn out of # and space characters.

What Is ASCII Art Generator?

A text-to-banner renderer backed by a small, original 5-row-tall bitmap font covering uppercase A-Z, 0-9, and space.

Each input character maps to a fixed 5-row-by-5-column glyph; glyphs are placed side by side, separated by a single blank column, to form the final banner.

How ASCII Art Generator Works

The input is uppercased (since the font only defines uppercase glyphs), then each character is looked up in the built-in glyph table.

The five rows of each character's glyph are concatenated horizontally (row 0 of every glyph forms the banner's first output line, and so on), producing a 5-line monospace block of text.

When To Use ASCII Art Generator

Use it to generate a quick banner or heading for a terminal splash screen, README, code comment, or plain-text document.

It's also handy for making short labels or watermarks stand out in any plain-text context that can't render actual images or bold styling.

Often used alongside ASCII Art Smiley Generator, ASCII Wave Drawer and ASCII Spiral Generator.

Features

Advantages

No dependencies or external font files, the glyph data is small and built directly into the tool.
Unsupported characters degrade gracefully to a blank glyph with an explicit note, rather than breaking the whole render.
Output is plain monospace text, so it pastes cleanly into any terminal, code comment, or plain-text file.

Limitations

Only supports uppercase A-Z, 0-9, and space; punctuation and lowercase-specific glyphs aren't available.
Capped at 20 input characters to keep the rendered banner a manageable width.

Examples

Rendering a short word

Input

HI

Output

##### ###  
  #  #   # 
  #  ##### 
  #  #   # 
  #  #   #

Each letter's 5-row glyph is drawn side by side with a single blank column between them; actual banner width depends on the letters used.

Mixing letters, a digit, and a space

Input

A 1

Output

5-row banner for 'A', a blank glyph for the space, and the digit glyph for '1'

Space is a fully supported character in the font (rendered as a blank glyph column, same as any other letter), so it doesn't trigger the unsupported-character note.

Best Practices & Notes

Best Practices

Keep the input short, single words or short acronyms read far more clearly as block-letter banners than full sentences.
Check the unsupported-character note after rendering if your text includes punctuation, since those spots will render as blank space.

Developer Notes

The font is a hand-authored `Record<string, string[]>` mapping each supported character to five 5-character-wide strings ('#' for filled pixels, ' ' for empty); rendering concatenates row `r` across every character's glyph with a single space separator, for `r` from 0 to 4, joined with newlines. This is an original block font made for this tool, not a transcription of FIGlet or any other external font standard.

ASCII Art Generator Use Cases

Generating a banner heading for a terminal splash screen or CLI tool
Making a short label or watermark stand out in a plain-text README or comment block
Quick, dependency-free ASCII art for a chat message or forum post

Common Mistakes

Expecting punctuation like "!" or "?" to render; the font only covers A-Z, 0-9, and space, so those spots come out blank.
Pasting a long sentence and getting an error, remember the 20-character cap and keep input to a short word or two.

Tips

Uppercase and lowercase input produce identical output, since lowercase is automatically converted before rendering.
Pair with ASCII Smiley Generator or ASCII Wave Drawer if you want to build a larger themed piece of plain-text art.
