How to Underline Text on LinkedIn (Works in 2026)

Underline text on LinkedIn? Sounds impossible, right? LinkedIn's editor doesn't have an underline button. But there's a Unicode trick that works perfectly.

How to Underline on LinkedIn

Unicode has dedicated underlined characters. You can generate them with Link-Polish:

1. Open Link-Polish
2. Type your text
3. Select it and click Underline (Ctrl+U)
4. Copy and paste into LinkedIn

When to Use Underline on LinkedIn

• Section headers in long posts
• Your call to action
• Key phrases you want readers to remember
• Links or references

Underline + Bold = Power Combo

For maximum impact, combine underline with bold. Use Link-Polish to create bold underlined text that really pops. This works great for headers and CTAs.

One warning: underline on the web traditionally means "clickable link." On LinkedIn, most users understand it's just formatting, but don't underline random words — use it intentionally.
