LinkedIn text formatter: bold, italic, lists and a post preview

How do you use the formatter?

Everything runs in your browser. Your text is never sent to a server, and the draft is saved only on your device.

1. Write or paste your post in the editor.
2. Select a word or phrase and click B for bold, I for italic or BI for both. T turns it back into plain text.
3. Select a few lines and click the dot, arrow or number to turn them into a list.
4. Check the preview on desktop and mobile, and what stays visible before "...more".
5. Click "Copy" and paste into LinkedIn.

How does bold text on LinkedIn work?

LinkedIn has no bold button in posts. Every "bold text" tool, this one included, swaps letters for characters from a Unicode block called Mathematical Alphanumeric Symbols. That block only has Latin and Greek letters and digits, so it can't style Hebrew, Arabic or most other scripts.

Since September 2026 there are reports that LinkedIn keeps real bold when you paste bold text from Google Docs or Gmail. It hasn't been announced and is reaching accounts gradually; on many accounts it doesn't work yet. Once it's stable, we'll add a "copy with real bold" button.

How many characters can a LinkedIn post have?

According to LinkedIn Help, a post is limited to 3,000 characters and a LinkedIn article to 125,000. The counter here counts characters the way JavaScript does, so each styled letter counts as two. That errs on the safe side.

More important than length is what people see before "...more". The feed shows only the first lines of a post, and most people decide from those whether to keep reading. Make the first line stand on its own.

When not to use fake bold

Styled Unicode characters look like letters, but they aren't. Screen readers may spell them out letter by letter or skip them, and search may not find a word written with them. Bold a few words at most, never a whole line, and never a name, phone number or link.
