TL;DR LinkedIn's post editor has no bold button. To bold text in posts, comments, or your bio, use a Unicode bold text generator — type your words, copy the styled output, paste it into LinkedIn. LinkedIn Articles and newsletters do have a native bold button, so no workaround needed there. Keep bold to one or two key phrases per post. Unicode bold is not real formatting, so screen readers may misread it.
LinkedIn doesn't give you a bold button in the regular post editor. No italic button either. You get a text box, some emoji, and that's about it. This catches people off guard because LinkedIn Articles — the long-form publishing feature — have had rich text formatting for years. But the standard post composer, the one most people use daily, remains plain text only as of 2026.
So how do people get 𝗯𝗼𝗹𝗱 𝘁𝗲𝘅𝘁 into their LinkedIn posts? Unicode. There's a set of mathematical symbols in the Unicode standard that look like bold Latin letters. When you paste them into LinkedIn, they display as bold — because they are bold characters, not plain letters with formatting applied. A text generator does the conversion for you.
Here's how to do it, step by step.
How to bold text in LinkedIn posts (step by step)
- Go to a Unicode bold text generator. Open the LinkedIn text formatter or the bold text generator on BoldlyType.
- Type or paste your text. Enter the words you want bolded into the input box.
- Select the bold style. Click the bold option from the style list. You'll see a preview of your text in 𝗯𝗼𝗹𝗱 𝗨𝗻𝗶𝗰𝗼𝗱𝗲 characters.
- Copy the output. Hit the copy button or select all and copy manually.
- Paste into LinkedIn. Open the LinkedIn post editor, type the rest of your post in normal text, and paste the bold text where you want it.
That's it. The bold characters are just text — they paste anywhere you can type. No browser extension, no app, no premium LinkedIn feature.
Where bold text works on LinkedIn
Not every field on LinkedIn treats Unicode bold the same way. Here's where it actually shows up:
Posts — Bold Unicode characters display correctly in regular LinkedIn posts. This is the most common use. People bold a hook line, a key stat, or a call to action.
Comments — Same deal as posts. Unicode bold characters paste into comments and render correctly on both desktop and mobile.
Headline (bio) — Your LinkedIn headline — the line under your name — accepts Unicode bold. Some people bold their job title or a keyword. It shows up in search results and on your profile card.
About section — The summary on your profile also supports Unicode bold. Useful for breaking up a long About section into scannable chunks.
Creator mode posts — If you've turned on creator mode, your posts still accept Unicode bold the same way.
Where bold text doesn't work reliably
Job titles and company names — LinkedIn's structured fields (the ones tied to your Experience section) don't always render Unicode characters correctly. Some mobile views strip them. Stick to plain text for job titles.
LinkedIn messaging — Unicode bold characters paste into DMs, but formatting can break depending on the recipient's app version and device. Don't count on it.
Some mobile views — Older versions of the LinkedIn app occasionally display Unicode bold characters as empty squares or question marks. This is rare on current iOS and Android builds, but worth knowing.
Method 2: Bold text in LinkedIn Articles
LinkedIn Articles are a different editor entirely. When you write an Article (click "Write article" from your profile or the post composer), you get a full rich-text editor with a toolbar. That toolbar has a B button for bold and an I button for italic — real formatting, not Unicode.
This means:
- You select text and press the bold button (or Ctrl+B / Cmd+B)
- The text is actually bold, not Unicode look-alike characters
- Screen readers can identify it correctly
- It works on all devices without rendering issues
If your content is long-form and you care about accessibility, Articles are the cleaner option. The trade-off is reach — Articles get less feed distribution than regular posts on most accounts.
Method 3: Bold text in LinkedIn Newsletters
LinkedIn Newsletters use the same rich-text editor as Articles. If you have newsletter access (available to creator-mode profiles meeting certain follower thresholds), you get the native bold button, italic, headers, bullet lists, and links. Same formatting capability, different distribution model — subscribers get notified.
The accessibility problem with Unicode bold
Here's the honest caveat. Unicode bold characters are not real bold formatting. They're mathematical symbols that happen to look like bold letters. Screen readers — the software used by blind and low-vision people — often read them incorrectly. A word like "𝗵𝗲𝗹𝗹𝗼" might be read as "mathematical bold small h, mathematical bold small e..." instead of "hello."
This matters if your audience includes people using assistive technology. It also means search engines don't treat Unicode bold text the same as plain text — LinkedIn's own search may not match a Unicode bold word to a normal-text query.
For a full breakdown of the trade-offs, see are Unicode fonts accessible. The short version: use Unicode bold sparingly, keep it to a word or short phrase, and don't bold entire paragraphs.
Best practices for bold text on LinkedIn
Bold one phrase per post, not everything. When everything is bold, nothing stands out. Pick the single most important phrase — a key number, a surprising claim, or your call to action — and bold that.
Use bold for the hook line. The first ~210 characters of a LinkedIn post show before the "see more" link. Bolding the opening line can increase the chance someone taps to expand.
Don't bold your entire post. Walls of bold text are harder to read than regular text. It defeats the purpose.
Keep accessibility in mind. If you're posting about disability, inclusion, or accessibility topics, using Unicode bold while talking about those subjects is a bad look. Use plain text or switch to a LinkedIn Article with native formatting.
Pair it with line breaks. Bold text works best in posts that already use white space and short paragraphs. The combination of structure and selective emphasis is what makes a post scannable.
Does bold text help LinkedIn reach?
There's a persistent claim that bold text improves LinkedIn engagement and algorithmic reach. The honest answer: there's no confirmed evidence that LinkedIn's algorithm treats Unicode bold text differently from plain text. What bold probably does is make your post more visually distinct in the feed, which may increase the stop-scroll rate. That's a human behavior effect, not an algorithmic one.

FAQ
How do I bold text on LinkedIn without an app?
Use a web-based Unicode text generator like the bold text generator. Type your text, select the bold style, copy the output, and paste it into LinkedIn. No app or extension needed — it runs in your browser.
LinkedIn's regular post editor is intentionally plain-text. The company hasn't added rich-text controls to the standard post composer, likely to keep posts lightweight and consistent in the feed. LinkedIn Articles and Newsletters use a separate editor that does include bold, italic, headers, and links.
Does bold text on LinkedIn hurt accessibility?
It can. Unicode bold characters are mathematical symbols, not real bold formatting. Screen readers may read each character as its full Unicode name instead of the intended word. Use bold sparingly — one or two key phrases — and avoid bolding entire paragraphs. See are Unicode fonts accessible for details.
Yes. Unicode bold characters paste into LinkedIn comments the same way they do in posts. Copy the styled text from a bold text generator and paste it into the comment field.
Does bolding text on LinkedIn improve engagement?
There's no confirmed evidence that LinkedIn's algorithm favors Unicode bold text. The benefit is visual — bold text stands out in the feed and may increase the chance someone stops scrolling to read your post. For more on this, see does bold text help LinkedIn reach.
Can I use bold text in my LinkedIn headline?
Yes. Your LinkedIn headline (the line under your name) accepts Unicode bold characters. Some people bold a job title or keyword. It displays on your profile card and in search results. Just keep it short — the headline has a 220-character limit.
What's the difference between Unicode bold and real bold on LinkedIn?
Real bold (available in LinkedIn Articles and Newsletters) is native rich-text formatting that screen readers understand. Unicode bold uses special mathematical symbols that look like bold letters but are technically different characters. Real bold is always better for accessibility; Unicode bold is the workaround for posts and comments where no formatting toolbar exists.
