How to Bold Text on LinkedIn

Quick answer: LinkedIn has no built-in bold button, so you make text bold using Unicode characters that look like bold letters. Type your text into a LinkedIn text formatter, select it, click Bold, then copy and paste it into your post. Or install the Post Formatter Chrome extension to bold text inline, right inside LinkedIn.

LinkedIn's post editor only accepts plain text — there's no B button like in Word or Google Docs. But you've probably seen posts with 𝗯𝗼𝗹𝗱 𝗵𝗲𝗮𝗱𝗹𝗶𝗻𝗲𝘀 that stop the scroll. The trick is Unicode: a set of real characters that already look bold. Here are the two fastest free ways to do it.

Method 1: Use a free LinkedIn text formatter

The quickest no-install option is an online bold text generator for LinkedIn:

Open the LinkedIn Text Formatter.
Type or paste the text you want to bold.
Select the words, then click Bold (or use the live preview to check the look).
Click Copy, then paste into your LinkedIn post. Done.

It's free, needs no account, and works on your phone or computer.

Method 2: Bold text inline with a Chrome extension

If you post often, copy-pasting gets old. The Post Formatter Chrome extension adds an inline toolbar so you can bold text directly inside the LinkedIn composer:

Install the free extension.
Start writing a LinkedIn post as usual.
Select text — a small toolbar appears. Click Bold (or press Ctrl+B).
That's it — no copy-paste, no separate tab.

Why this works (the Unicode trick)

These tools convert ordinary letters into characters from the Unicode Mathematical Alphanumeric Symbols block. The letter "a" becomes "𝗮", "b" becomes "𝗯", and so on. Because they're real text characters — not HTML or CSS styling — they survive copy-paste and render correctly on LinkedIn, plus X, Facebook, Threads, Bluesky and anywhere else that accepts text.

Best practices (don't overdo it)

Bold for emphasis, not decoration. Highlight your hook, a key stat, or a section label — not whole paragraphs.
Keep hashtags and keywords plain. LinkedIn search can't index bold Unicode words, so don't bold terms you want to be found by.
Mind accessibility. Screen readers may skip or misread Unicode styling, so never put essential meaning only in bold characters.

Frequently asked questions

Why is there no bold button on LinkedIn?

LinkedIn's post composer only accepts plain text, so it has no rich-text buttons for bold or italic. The workaround is to use Unicode characters that look like bold letters — they paste in as normal text but render in a bold style everywhere.

Does bold text hurt my LinkedIn reach?

Bold text itself does not reduce reach, but overusing it can. Unicode characters are not indexed by LinkedIn search and may not be read correctly by screen readers, so bold a few key words and headlines rather than entire posts, and keep hashtags in plain text.

Will bold text show correctly on mobile?

Yes. Because the characters are real Unicode text, they display correctly in the LinkedIn mobile app, desktop app, and web — on any device and operating system.

Is it free to bold text on LinkedIn?

Yes. The LinkedIn Text Formatter and the Post Formatter Chrome extension are both free, with no sign-up and no paid tier.
