How to bold text in a LinkedIn post
- Write or paste your text into the box at the top of this page.
- Find the bold variant (or italic, or bold italic) and copy it.
- Paste the result into your LinkedIn post, headline, or profile.
That is the whole trick. LinkedIn has no formatting toolbar for bold or italic, but every LinkedIn surface renders Unicode characters, so the bold variant above shows up bold in the feed, in comments, in direct messages, in your headline, and on mobile.
Why LinkedIn has no bold button
LinkedIn's post composer is plain text. There is no bold toggle, no italic toggle, and no underline button, because LinkedIn chose not to add rich-text formatting to feed posts. This formatter works around that by converting your text into Unicode characters that already look bold or italic. Copy the converted text, paste it into LinkedIn, and it renders exactly how you see it here.
What the variants are, and when to use each
- Bold (sans-serif): the cleanest LinkedIn bold. Use it for key points, names, numbers, and callouts.
- Italic (sans-serif): the natural fit for quotes, book titles, and soft emphasis.
- Bold italic (sans-serif): high-impact emphasis. Good for hooks at the top of a post or pull quotes.
- Serif bold and serif italic: a more formal tone. Useful for thought-leadership posts or anything writing-heavy.
- Monospace: stands out in a feed full of sans-serif text. Use it sparingly for product names, code, or single-line labels.
- Script: cursive handwriting. Works for signatures and decorative use, but keep it short.
- Underline and strikethrough: built from combining characters, so they work even in fields that reject Unicode bold.
Where bold and italic text works on LinkedIn
- Feed posts and reposts
- Comments and replies
- Your headline, About section, and job titles
- Company page tagline and description
- Newsletter posts and LinkedIn articles
- Polls and carousel titles
- Direct messages (InMail)
Accessibility, SEO, and search tradeoffs
The Unicode bold characters are technically mathematical symbols, not regular letters. That has two consequences worth knowing about before you lean on the formatter every day:
- Screen readers can read the characters as "mathematical bold small a, mathematical bold small b" or skip them entirely. Do not format body text, alt text, or anything critical to a blind reader.
- LinkedIn search indexes plain letters. A headline typed entirely in Unicode bold will not match a recruiter searching for your role or company in regular text. Keep the keywords a recruiter or hiring manager would type in plain characters.
Use bold and italic for emphasis, not for every noun. A single bold phrase in a post pulls the eye. A whole paragraph in bold reads like shouting and hurts your reach.
Does the formatter work on mobile?
Yes. The output is plain Unicode text, so you can copy it on desktop and paste it into the LinkedIn iOS or Android app, or do the whole thing on your phone in one browser tab and paste into the LinkedIn app in another. There are no images, no rich-text payloads, and no clipboard weirdness to break along the way.
Frequently asked questions
How do you bold text on LinkedIn?
LinkedIn does not have a built-in bold button for posts, articles, or profiles, but it does render Unicode characters. Paste your text into the formatter above, copy the bold variant, and paste it into LinkedIn. The text keeps its bold appearance in feed posts, headlines, About sections, job titles, company pages, and comments.
Can you use italic text on LinkedIn?
Yes. LinkedIn does not offer an italic toggle, but mathematical italic Unicode letters render as italic in every LinkedIn surface. Copy the italic variant from the formatter and paste it into your post or profile.
Is this actually bold text, or a font trick?
It is a Unicode trick. The characters come from the Mathematical Alphanumeric Symbols block in Unicode, which defines bold, italic, bold italic, monospace, and script variants of every letter and digit. LinkedIn renders those code points using the visually bold or italic forms. The underlying text is still text, so it copies, pastes, and shows up correctly on phones and desktops.
Will bold text on LinkedIn hurt accessibility?
It can. Screen readers sometimes spell out each character or skip them entirely because they are technically mathematical symbols, not regular letters. Use bold sparingly, limit it to short highlights rather than full sentences, and never format body copy or links that need to be discoverable.
Does LinkedIn search still find bold text?
Usually not. LinkedIn search indexes plain Latin characters, so a headline written entirely in Unicode bold will not match searches for the regular version. Keep the critical keywords (your role, company, skills) in plain text and use bold only for emphasis.
What font does LinkedIn use?
LinkedIn uses its own type family called Source Sans Pro (and Source Sans 3 on newer surfaces) for most of the web interface, with system UI fonts on mobile. You cannot change the rendering font from inside a post, but the Unicode variants above let you mix bold, italic, and monospace styles into any text field.
Does the formatter work for LinkedIn headlines and the About section?
Yes. Because it outputs real Unicode characters, the formatted text works anywhere LinkedIn accepts text input: feed posts, comments, articles, your headline, the About section, job titles, company descriptions, newsletter posts, polls, and direct messages.
Can I bold text on LinkedIn mobile?
Yes. Paste the formatted text from a notes app, Safari, Chrome, or the LinkedIn composer on iOS and Android and it renders bold in the same way as desktop. The character set is identical on every platform.
Is the formatter free?
Yes. Everything runs in your browser, there is no sign-up, and there is no character limit. Nothing you type leaves the page.
