Underlining text online used to require HTML or rich text editors. Now you can add underlines anywhere with Unicode combining characters. Our generator attaches the combining low line character (U+0332) to each letter, creating the appearance of continuous underlining across your text.
Underlined text stands out in feeds full of plain text. Use it to emphasize key points in captions, highlight important dates or names in announcements, or make your bio pop. The visual break from normal text naturally draws the eye, giving you an edge in the scroll.
Instagram bios and Twitter profiles are prime spots for underlined text. Since these platforms strip most formatting, Unicode underlines are one of the few ways to add visual emphasis. Pair it with other text styles for a more elaborate aesthetic profile.
The underline sits below the baseline of each character, so it looks slightly different from traditional word processor underlining. Letters with descenders like g, j, p, q, and y might have the line intersect with their tails. This is normal Unicode behavior and actually adds character.
Copy the output directly from our generator and paste wherever you need it. The underline travels with your text across platforms, email, documents, and messaging apps. No installation required, and it works on both desktop and mobile devices.
