How to bold text on a LinkedIn post
LinkedIn gives you a plain text box with no bold button. This tool works around that by swapping each letter for its Unicode mathematical sans-serif twin, which is a normal character that keeps its shape wherever it is pasted.
- Type or paste your post into the editor above.
- Select the words you want to emphasize.
- Press the bold, italic, underline, or strikethrough button, or use Ctrl + B.
- Select Copy to Clipboard, then paste into the LinkedIn post box.
Where LinkedIn formatting works
Because the output is made of ordinary characters, it pastes into any LinkedIn field that accepts text: posts, comments, your headline, the About section, company pages, and direct messages. The same characters also work on X, Facebook, Instagram, and most other platforms.
LinkedIn character limits
| Field | Limit | Worth knowing |
|---|---|---|
| Post | 3,000 characters | Roughly the first 210 show before “see more” |
| Comment | 1,250 characters | Formatting pastes in the same way |
| Headline | 220 characters | Shows next to your name across the site |
| About section | 2,600 characters | Only the first few lines show unfolded |
The counter under the editor tracks the 3,000 character post limit and flags the point where LinkedIn collapses your post behind “see more”, so you can see whether your opening lines carry the post on their own.
When to leave text plain
Styled characters are a visual trick, so they carry real trade-offs. Screen readers often read them letter by letter or skip them, and LinkedIn search does not match them against the plain spelling of a word. Keep the body of your post in ordinary characters, use styling for a headline or a few key terms, and never put information that only exists in styled form.

Writing Tips

- Bold one headline and at most a few keywords per post.
- Three to five hashtags outperform long hashtag lists.
- Short paragraphs with blank lines read better on mobile.
Accessibility Note
- Screen readers often skip Unicode styled letters or read them one at a time.
- Keep the body of your post in plain characters.
- Never put essential information in styled text alone.
- Hashtags read best in CamelCase, such as #AIinEducation.
- How does bold text work on LinkedIn?
- LinkedIn posts have no rich text, so this tool swaps each letter for its Unicode mathematical sans-serif equivalent. Those are ordinary characters, so they survive a copy and paste.
- Will screen readers read Unicode bold text correctly?
- Many will not. Use styled text for short emphasis and keep the body of your post in plain characters.
- How many characters can a LinkedIn post contain?
- Up to 3,000. Roughly the first 210 appear before the “see more” link on desktop.
- Is this tool free?
- Yes. No account, no upload, no cost. Your draft stays in your browser.
