Everything for a post people read
Bold and italic that work on LinkedIn
LinkedIn has no bold button. We turn your selection into styled Unicode characters that display everywhere: mobile app, desktop, notifications.
Faithful preview, desktop and mobile

Frequently asked questions
Can you write in bold on LinkedIn?
Not with a button: LinkedIn only accepts plain text. The workaround is to replace letters with their bold Unicode equivalents (𝗮, 𝗯, 𝗰…). The editor does this when you copy.
Does bold text show on mobile?
Yes. Styled Unicode characters display on the LinkedIn iOS and Android apps as well as on desktop.
Does bold text work with accented letters?
Yes. Unicode has no bold “é”: we make the letter bold and keep the accent on top. It renders correctly on most devices; some fonts shift the accent slightly.
Is bold text bad for search or accessibility?
Styled letters are not found by LinkedIn search and are poorly read by screen readers. Keep them for a few key words: the tool warns you when you use too many.
How many characters can a LinkedIn post have?
3,000 characters at most. Note that a bold or italic letter counts twice. The editor's counter counts exactly like LinkedIn.
Are my posts saved?
No. Your draft stays in your browser. Text is sent to our server only when you click an AI assistant action, and it is not kept there.
