Underline Text Generator

Insert the Unicode COMBINING LOW LINE U+0332 after every non-whitespace code point to create an underline that travels with copied text. For example, `Text 20` becomes `T̲e̲x̲t̲ 2̲0̲`; spaces, tabs, and line breaks stay unmarked. This alters the character sequence rather than applying HTML, CSS, or rich-text decoration. Line position, search behavior, selection, and character counts may vary by font and app, while emoji or existing combining marks can render unevenly because transformation is code-point based. It is a common way to fake an underline in plain-text fields that don't support real HTML formatting, such as bios or chat messages. Preview and generation remain local, and another Unicode style can be selected before copying.

Type or paste text into the Underline Text Generator box; the result appears instantly and a copy button sends it straight to your clipboard.

The result is plain Unicode text, so its shape depends on the destination's font — most current apps render it fine, but very old software can show empty boxes.

Some platforms count these characters differently toward length limits than plain ASCII, and a few spam filters flag unusual Unicode more readily — preview the result first.

Read the output before publishing it and keep the plain original text handy in case a platform strips or mis-renders the styled version.

If Underline Text Generator isn't quite the look you want, this collection also has the Italic Text Generator and Strikethrough Text Generator for the same input.

Every conversion happens locally in your browser; the text you type is never uploaded, logged, or stored by this tool.
