LinkedIn text formatter: bold, italic and a live character count
LinkedIn posts have no bold or italic button. Type or paste your post below, select the words you want to stand out, and pick a style. Then copy the text into LinkedIn. You also see your character count against the 3,000 limit and where the feed cuts your post with “…see more”.
- Characters
- 285 / 3,000
- If styled letters count as 2
- 330 / 3,000
Styled letters take two units in most counters. Stay under 3,000 on the higher number to be safe.

78 characters show before “…see more”. Approximate: LinkedIn does not publish the fold. It falls around 210 characters on desktop, or after the third line, and moves with screen width.
How LinkedIn bold text works
A LinkedIn post is plain text. There is no hidden formatting that could make a word bold. What this tool does instead is swap each letter for a look-alike character from Unicode’s Mathematical Alphanumeric Symbols block. 𝗔 is not a bold A. It is a different character that happens to look like one, so it stays bold wherever you paste it.
That is also the catch. Unicode itself says these characters are “intended for use only in mathematical or technical notation”. Because the letters are different characters, anything that reads text as letters can trip over them: screen readers, search boxes, and spell checkers. The section below on when not to use it covers the trade-off.
| Style | Looks like | Notes |
|---|---|---|
| Bold | 𝗕𝗼𝗹𝗱 𝘁𝗲𝘅𝘁 𝟮𝟬𝟮𝟲 | Letters and digits. The style most posts use for a hook or a heading. |
| Italic | 𝘐𝘵𝘢𝘭𝘪𝘤 𝘵𝘦𝘹𝘵 | Letters only. Digits stay plain because Unicode has no sans-serif italic digits. |
| Bold italic | 𝘽𝙤𝙡𝙙 𝙞𝙩𝙖𝙡𝙞𝙘 | Letters only. Use it sparingly; it is the hardest of the set to read. |
| Monospace | 𝙼𝚘𝚗𝚘𝚜𝚙𝚊𝚌𝚎 𝟷𝟸𝟹 | Letters and digits, typewriter style. Handy for a command or a code name. |
| Strikethrough | S̶t̶r̶i̶k̶e̶t̶h̶r̶o̶u̶g̶h̶ | Adds a combining line through each character instead of swapping the letter. |
| Underline | U̲n̲d̲e̲r̲l̲i̲n̲e̲ | Adds a combining line under each character. Can look like a link, so use it rarely. |
Does formatting count toward LinkedIn’s character limit?
Yes. A LinkedIn post takes up to 3,000 characters, and every styled letter counts. The open question is how many each one costs. A styled letter is one character to a person, but it takes two units in UTF-16, the encoding most web counters use. LinkedIn does not publish which way its own counter works.
So the formatter shows both numbers: characters as you see them, and the count if every styled letter costs two. For plain text the two match. With a lot of bold they drift apart. Keep the higher number under 3,000 and the post will fit either way.
The number that shapes a post is smaller than 3,000. Only the first two or three lines show before “…see more”, so the hook has to work in about 140 characters on a phone. Our guide to the LinkedIn post character limit lists every field’s limit and explains the fold.
When not to use bold and italic
- Whole sentences. A screen reader may read out one styled letter as “mathematical sans-serif script t”, as the disability charity Scope explains. Style a few words, not a paragraph, and never put the only copy of a key point in styled text.
- Hashtags, @mentions, links and names. Keep them plain. A styled hashtag is made of different characters, so it may not work as a hashtag, and a styled name is harder to find.
- Words people might search for. To a search box, a bold word is a different word. If you want a post found by a term, leave that term plain.
- Every other line. Bold works because it is rare. If half the post is bold, nothing stands out.
Schedule the post instead of posting it now
Schedule & Chill is a free LinkedIn scheduler. Paste the formatted text, pick a time, and it publishes then. A free account connects 2 channels and schedules up to 500 posts a month, and AI tools like Claude can schedule posts for you through its MCP server. If you only post once in a while, you do not need it: LinkedIn’s own scheduler is fine for that.

LinkedIn formatting questions
The LinkedIn post composer has no bold or italic button. To get bold words, type your post in a formatter like this one, select the words, press Bold, copy the result and paste it into LinkedIn. The formatter swaps each letter for a bold look-alike character from Unicode, so the styling survives the paste.
Yes. There is no account, no sign-up and no limit on use. It runs entirely in your browser, and nothing you type is sent to our servers.
Yes. Every character counts toward the 3,000-character post limit. Each styled letter is one character, but it takes two units in the UTF-16 encoding that many counters use, and LinkedIn does not publish which way it counts. The tool shows both numbers. Keep the higher one under 3,000 to be safe.
Often not well. The bold and italic letters are separate mathematical symbols, so some screen readers announce them one by one or skip them. Keep styled text to a few words, and never put the only copy of an important point in it.
You can paste the same styled characters anywhere LinkedIn accepts text. They count toward each field’s limit the same way. Keep names, hashtags, @mentions and links plain so they still work as they should.
LinkedIn does not publish it. The fold moves with screen width and line breaks: roughly 140 characters on a phone and 200 to 250 on desktop, or after the third line, whichever comes first. The preview above uses 140 and 210 and labels them as estimates.
