Frequently asked questions
How do I make underlined text for Instagram or TikTok?
Type your text into the box above and copy the result. It uses Unicode underline characters instead of formatting, so the underline shows up anywhere plain text is accepted.
Why use Unicode instead of the underline button?
Most social platforms strip formatting like bold and underline from bios and usernames. Unicode underlined characters are part of the text itself, so they survive pasting.
What is the difference between single and double underline?
Single underline adds one combining line under each character, while double underline adds two parallel lines for a stronger effect.
Will underlined text work in all apps?
It works in most modern apps and browsers. Very old devices may show the underline slightly offset, but the text stays readable.
Is this tool free?
Yes, it is free with no signup and no limits.
Is my text sent to a server?
No. The styling runs in your browser with JavaScript, so your text never leaves your device.
