Underline Text Generator
Add underline to text using Unicode combining characters. Works anywhere — Instagram, Discord, Twitter, WhatsApp.
Three steps to get started
Type or paste text
Enter the text you want to underline.
Underline added
Unicode combining characters draw a line under each letter: U̲n̲d̲e̲r̲l̲i̲n̲e̲.
Copy and share
Click Copy and paste into Instagram, Twitter, Discord, or any platform.
U̲n̲d̲e̲r̲l̲i̲n̲e̲ anywhere — no HTML required
Underlined text is a classic typographic convention for emphasis, hyperlinks, and titles. Most social media platforms strip HTML formatting, but they can't strip Unicode combining characters — because those characters are part of the text itself.
The underline generator uses the Combining Low Line (U+0332), a Unicode combining character designed to draw a line below any character it follows. Since it attaches to the character, it copies and pastes along with the text.
Common uses:
- Instagram bio headers: U̲n̲d̲e̲r̲l̲i̲n̲e̲ section labels
- Discord messages: emphasize key terms
- Twitter/X posts: visual formatting without Markdown
- Creative writing and social content
