Frequently Asked Questions
How do I underline text on LinkedIn?
LinkedIn does not have a native underline button for posts (unlike the Article editor). To underline text in LinkedIn posts, use a Unicode underline generator like this one. It applies a Unicode combining underline character (U+0332) under each letter, which displays as underlined text in LinkedIn posts, comments, and bios.
Does underlined text work in LinkedIn comments?
Yes. Unicode underline characters work in LinkedIn posts, comments, messages, the About section, and profile headlines — anywhere LinkedIn accepts plain text.
Is underline text readable on LinkedIn mobile?
Yes. Unicode combining characters render the same way on the LinkedIn mobile app as on desktop. The underline appears under each character on both iOS and Android.
When should I use underline text on LinkedIn?
Use underline sparingly to highlight the most important phrase or call to action in your post. Good uses: underlining a key stat, a CTA like "Save this post", or a section header in a long-form post. Avoid underlining entire paragraphs as it reduces readability.
