The Underline Text Generator adds an u̲n̲d̲e̲r̲l̲i̲n̲e̲ to your text using Unicode, so you can paste underlined text into bios, chats, and posts that offer no underline button. Type your text and copy the underlined version in a click.
It works by adding a combining underline mark to each character, so the line stays when you copy and paste. Everything runs in your browser.
How to underline text

How the underline works
Rather than a special alphabet, this style appends a combining low-line character (U+0332) after each letter, which the device draws as a continuous underline. Because the mark is part of the text, the underline survives copy-and-paste into apps that have no formatting — useful for emphasis in bios, usernames, and messages.
Compatibility notes
Combining underline is widely supported, though the exact thickness and position of the line can vary slightly between fonts. On a few systems combining marks may render imperfectly. Screen readers generally read the underlying letters, so use it for visual emphasis rather than essential meaning. For a crossed-out look instead, try the strikethrough generator.
Frequently Asked Questions
How do I underline text in a bio or chat?
Type it here, copy the underlined version, and paste it. The underline is a combining Unicode mark, so it stays even where there is no underline button.
Why does my app have no underline option?
Many bios and chat fields strip formatting. This tool bakes the underline into the characters so you do not need a button.
Does it work everywhere?
Combining underline is broadly supported; the line’s look can differ slightly by font, and a few older systems render it imperfectly.
Can I underline numbers and symbols too?
Yes — the combining mark is added to each character, including digits and most symbols.
