LinkedIn Text Formatter: Bold, Italic & Bullets for Posts

LinkedIn posts do not support native bold or italic. Paste Markdown or plain text — including a draft copied from ChatGPT — and copy LinkedIn-ready text that uses Unicode lookalike letters. Not affiliated with LinkedIn.

  • No signup
  • No upload
  • Unicode bold and italic

Posts do not render Markdown. The syntax this page accepts is on the cheatsheet. Sending a Slack message instead? Markdown to Slack. Need the words with no styling at all? Markdown to plain text.

#hiring is a hashtag, not a heading. @you stays as typed.

3. Post

LinkedIn's help center says a post can be up to 3,000 characters. It does not say whether that is a Unicode code point or a UTF-16 code unit. A bold or italic letter from this page is one code point and two UTF-16 units, because it sits outside the Basic Multilingual Plane. The counter shows both. The UTF-16 number is the cautious one.

Why this formatter

Lookalike letters, not a bold button.

A post, a comment, and most other LinkedIn boxes are plain text. Articles and newsletters do have a rich-text editor; this page is not for those. The letters it produces are real Unicode characters (mathematical sans-serif bold and italic). They are not a font style LinkedIn can turn off, and they are not affiliated with LinkedIn.

  • Local-first

    The conversion runs in your browser. Nothing is uploaded, logged, or stored.

  • Leaves the rest alone

    Punctuation, emoji, non-Latin text, URLs, hashtags, and @mentions are copied through. Only A–Z, a–z, and bold digits change.

  • Use it sparingly

    Screen readers may spell these letters out or skip them. A styled word may not match LinkedIn search. Keep it to a headline or a few phrases, not the whole post.

  • Instant preview

    No Convert button. The post text updates as you type, and the count updates with it.

How it works

Three steps, no friction.

  1. 01

    Paste or select

    Drop in Markdown, or select a phrase and press Bold or Italic. A space after # makes a heading; #hiring stays a hashtag.

  2. 02

    Read the preview

    Lists become bullets, headings become a bold line, and links become text (url). Line breaks stay. Trailing spaces are stripped.

  3. 03

    Copy and post

    Paste into LinkedIn on desktop or mobile. If a font shows a box, the characters are still right. Reset to plain text maps them back to A–Z.

What changes

Markdown in, post text out.

Unclosed markers stay as you typed them. A font that does not include these letters draws a box instead; copying still puts the characters on the clipboard.

FAQ

Common questions

Can you bold text in a LinkedIn post?
Not with a formatting button. A LinkedIn post is plain text: there is no bold or italic control, and Markdown asterisks show up as asterisks. This page substitutes Unicode lookalike letters — mathematical sans-serif bold and italic — that most phones and desktops draw as bold or italic. LinkedIn Articles and newsletters are different: those editors have real rich text. This tool is not affiliated with LinkedIn.
How do I bold text in a LinkedIn post on mobile?
The LinkedIn app does not format posts. Write the post here, select a phrase and press Bold, or wrap it in **double asterisks**, then copy the result and paste it into the app. The styling is in the characters themselves, so it survives the paste.
Is bold Unicode text bad for accessibility?
It can be. Screen readers may spell these letters one by one, announce them as a mathematical symbol, or skip them. Use the effect on a headline or a few words, not a whole post. A styled word may also fail to match a LinkedIn search for the plain spelling.
Does LinkedIn support Markdown?
Not in posts, comments, or messages. **bold** stays as asterisks. LinkedIn Articles and newsletters have a formatting toolbar, which is real rich text, not Markdown. The syntax this page accepts is the same as the cheatsheet. If you want the words with the styling removed, use Markdown to plain text.
Why do some characters show as boxes?
The bold and italic letters live in Unicode's Mathematical Alphanumeric Symbols block. When a font has no glyph for them, the system draws a box. The copied text is still those characters; another phone or computer may show them. Combining strikethrough and underline are more widely available and can still fail on an older font.
Do Unicode bold letters count as one character toward the 3,000 limit?
LinkedIn's help center says a post can be up to 3,000 characters. It does not say whether a character is a Unicode code point or a UTF-16 code unit. A bold or italic letter from this page is one code point and two UTF-16 code units, because it sits outside the Basic Multilingual Plane, the same way many emoji do. This page shows both counts. The UTF-16 number is the cautious one: if LinkedIn counts code units, a post written only in these letters reaches 3,000 at 1,500 letters. Ordinary letters, spaces, line breaks, and the combining strike and underline marks are one UTF-16 unit each.
