ASCII Banner Generator

The ASCII Banner Generator wraps your text in a decorative box, drawing a border around one or more lines and optionally centering the content inside it. It is built for the headers and callouts you see at the top of README files, in CLI welcome messages, and in plain-text documents where a framed block of text signals an important section. You provide the lines, choose a border style, and the tool assembles a tidy, aligned banner.

To build the box, the generator measures the widest line of your text, pads every line to that common width, and then draws the top edge, side walls, and bottom edge using border characters — anything from simple plus-and-dash ASCII to Unicode box-drawing lines for a smoother look. Centering works by splitting the leftover horizontal space evenly on each side of each line, so short lines sit symmetrically within the frame while the border stays perfectly rectangular.

Banners are handy as section dividers in long config files and logs, as eye-catching titles above a directory tree or code sample, as headers in scripts that print to the console, and as framed notices in plain-text emails. Because the result is monospaced text, it travels cleanly into Markdown code blocks, terminals, and chat without any image dependency.

Keep individual lines reasonably short so the box does not exceed your terminal or code-block width, and decide up front whether you want left-aligned or centered text since centering reads best for titles while left alignment suits lists. For oversized lettering rather than a framed box, generate the words with the Text to ASCII Art tool first, then drop that block inside a banner for a layered header effect.
