Frequently Asked Questions

Yes. The formatter converts your selected text to Unicode Mathematical Bold characters (a separate Unicode block), which LinkedIn renders as bold-looking text on desktop, iOS, and Android. It works in posts, comments, headlines, and your About section.
3,000 is LinkedIn's current limit for feed posts. Comments are limited to 1,250. The counter turns orange above 2,700 and red if you exceed the limit.
No. Unicode characters are part of the text itself, not formatting markup — they'll survive any copy, paste, or re-share.
Some screen readers handle Unicode Mathematical letters poorly. Use bold and italic for emphasis — not for core content that screen-reader users need to hear correctly.
No. All formatting happens in your browser via JavaScript. Nothing is sent to our servers.

Pro Tip

For a LinkedIn hook, start with a one-line question or statistic on its own line. LinkedIn truncates posts after ~210 characters on desktop and ~140 on mobile — put your strongest line first.
