LinkedIn has no bold button, and never will
The LinkedIn editor takes plain text. No formatting bar, no keyboard shortcuts, and HTML tags do nothing: type one and it publishes as written.
What this tool does is swap each letter for a Unicode character that already carries that stroke. Bold, italic and monospace come from the Mathematical Alphanumeric Symbols block. Underline and strikethrough work differently: they stack a line over each letter using a combining character.
Because the formatting travels inside the text itself, it survives copy and paste anywhere.
Which style to use, and when
Bold is the only one that genuinely works for emphasis. It reads at a glance in the feed and holds up on mobile.
Italic reads worse on small screens, and on some Android fonts it looks almost identical to regular. Use it for quotes, not emphasis.
Strikethrough works for the before-and-after device: a crossed-out price, a discarded idea. Sparingly, because it fills the line with noise.
Monospace looks right for code snippets or aligned figures, and wrong for everything else.
Underline rarely pays off: on a social network, underline means link, and it confuses people.
The cost nobody mentions
A post allows 3,000 characters. Styled letters cost twice as much as normal ones, because they live outside Unicode's basic range.
Underline and strikethrough are worse still: they add an extra character per letter, so a struck-through sentence costs double the plain one.
The counter below the box shows the real total, not the number of letters you can see.
Before you overdo it: accessibility
Screen readers do not recognise these characters as letters. VoiceOver and NVDA spell them out one by one or skip them, so a whole styled paragraph can be unreadable for a blind reader.
They do not help search either: engines treat them as odd symbols, not as the words they represent.
Three or four highlighted words per post. That is the point where formatting helps and does not yet get in the way.
Frequently asked questions
- Why do my accents break?
- Because the Unicode bold block has no accented vowels or ñ. Turn on «keep accents» to stack the mark on the bold letter, or use the tool dedicated to that problem.
- Does it work in comments?
- Yes. It works in any LinkedIn text field: posts, comments, headline, About and messages.
- Does it look the same everywhere?
- Bold and monospace do. Italic depends on the system font and on some Android devices barely differs from regular.
- Can I get plain text back?
- Yes. Paste the styled text and press «Remove formatting».
- Do you send my text to a server?
- No. The conversion happens entirely in your browser. Your text never leaves your machine.
