Underline Text Generator

By Abdullah · Updated July 18, 2026 · LinkedIn ↗

Add a real, portable line under any text — u̲n̲d̲e̲r̲l̲i̲n̲e̲ — that survives pasting into apps with no formatting buttons at all. Single, double, dotted and overline styles, free and instant. Want the line through the middle instead? Use the crossed out tool.

Tap Copy next to any style. Nothing you type is stored or sent anywhere.

Why you cannot normally underline text online

Instagram bios, tweets, Discord usernames, YouTube comments — none of them have an underline button, and pasting underlined text from a document silently drops the line, because that underline was formatting stored outside the characters. This generator takes a different route: it attaches a Unicode combining low line to every character, making the underline part of the text itself. Wherever the characters go, the line goes too. The mechanics are the same family of marks explained in Unicode explained.

How to underline text in 3 steps

1. Type your text

Any phrase — the line attaches to every character live.

2. Pick a line style

Single, double, dotted, overline or full stack.

3. Copy & paste

Paste into any bio, comment or chat — the line travels with it.

One playful use: an underlined word in a bio looks exactly like a hyperlink. It is not clickable, but it draws the eye the way links do — handy for pointing at the one link your profile actually has.

Where underlined text earns its keep

Screen readers announce combining marks inconsistently, so underline decoratively — never as the only signal that something is important.

Underline text FAQ

How do I underline text on Instagram or Twitter?
Neither platform has an underline button, so use this generator: it attaches a Unicode combining low line to each character, making the underline part of the text itself. Copy the result and paste it into your bio, caption or display name.
Why does my underline disappear when I paste from Word?
Word’s underline is formatting stored outside the characters, and plain-text fields discard formatting. Unicode underlined text keeps the line because it lives inside the characters — that is exactly what this tool produces.
Is underlined text clickable like a link?
No — it just looks like one. That resemblance is useful for drawing attention, but the text will not actually navigate anywhere when tapped.
Does Unicode underline work in Discord usernames?
Yes. Discord’s own __underline__ markdown only works inside messages, but this Unicode version works in usernames, nicknames and channel names as well, because it is plain text to Discord.
Is the underline text generator free?
Yes — free, no sign-up and no limits. Everything runs in your browser and nothing you type is stored.

Where to go next

Underlining is one mark from a bigger toolbox — move the line up and you get the middle-strike of crossed out text, put lines on both sides and you get stacked text, stack marks at random and you reach cursed text. If your goal is pure emphasis, compare against the bold text generator — weight often beats lines in crowded feeds. The complete kit lives at the text effects hub.
