ASCII Art Generator

Turn short words into copy-ready ASCII, block, or dot-style text art with width and unsupported-character diagnostics.

Runs in your browserNothing you type is sent to a server.

Input and result

What you type is kept in this browser only. Reopen to restore your last run.

Use cases

  • Generate short ASCII banners for comments, readme sections, release notes, and profile text.
  • Compare ASCII-safe output with block or dot styles before copying.
  • Check width and unsupported characters so text art does not wrap unexpectedly.

Examples

Common input
BOB
Generate short copy-ready ASCII banners and check width before using them in comments or docs.
Typical output
#### ### #### # # # # # # #### # # #### # # # # # # #### ### ####
Use this as a quick sanity check before copying results.

Common mistakes

  • Unsupported characters are replaced with question marks because this generator uses a small browser-local bitmap alphabet.
  • Wide banners can wrap in narrow chat, terminal, profile, or comment fields.
  • Block and dot styles use Unicode characters, so use the hash style when ASCII-only output is required.

Before you copy

  1. 1Keep the input short enough for the destination width.
  2. 2Use hash style for ASCII-only contexts and preview block styles in the target app.
  3. 3Check unsupported-character count before sharing generated art.

Sources

  • ASCII is 94 printable characters, 0x20-0x7E

    RFC 20 defines exactly 94 printable characters in 7 bits. Art drawn with block characters is no longer ASCII, so it turns into question marks wherever only ASCII is accepted - old terminals, some log viewers, mail headers.

    Basis: RFC 20

  • Mixing CJK or emoji breaks the alignment

    Unicode assigns every character an East Asian Width, and the ones marked W or F take two cells in a monospace font (UAX #11). If one line of your art is skewed, that line contains a full-width character.

    Basis: UAX #11

  • The destination must not collapse spaces

    CSS Text requires white-space: pre to keep runs of spaces and line breaks. The default, normal, collapses them - which is why pasting art straight into a web page squashes it onto one line.

    Basis: CSS Text Level 3

FAQ

Does ASCII Art Generator upload my input?

No. This tool runs in your browser unless the privacy badge explicitly says a server route is required.

Can I use this for production secrets?

Avoid pasting sensitive production data into any website. Prefer local test data or redacted payloads.
