LinkedIn posts are plain text: the post box has no bold or italic button. A LinkedIn text formatter gets around that by swapping letters for Unicode characters that look bold, italic or struck through, which you then paste into LinkedIn. Write or paste your post below, select the words you want to style (or select nothing to style the whole post), and click a style. The preview shows roughly where LinkedIn will cut the post with "...see more", and the counter tracks LinkedIn's 3,000-character post limit. Everything runs in your browser; your text is not sent anywhere.

How does a LinkedIn text formatter work?
Unicode, the standard that defines every character your phone and laptop can show, includes whole alphabets of bold, italic and monospace letters. They were added for mathematical notation, where a bold x and a plain x mean different things. Because they are separate characters, they survive a copy and paste into LinkedIn, which only takes plain text. The formatter replaces each letter you select with its styled twin. Strikethrough and underline work differently: the tool adds a combining mark after each character, which draws a line through or under it.
| Style | Looks like | How it is made | Good for |
|---|---|---|---|
| Bold (sans-serif) | π£πΆπ½π²πΉπΆπ»π² | Mathematical sans-serif bold letters and digits | The hook, one key number, a section label |
| Italic (sans-serif) | ππͺπ±π¦ππͺπ―π¦ | Mathematical sans-serif italic letters (digits stay plain) | A book or report title, a quoted phrase |
| Bold italic | πππ₯ππ‘ππ£π | Mathematical sans-serif bold italic letters | Rarely; it is the hardest style to read |
| Serif bold | ππ’π©ππ₯π’π§π | Mathematical bold letters and digits | When you want bold to stand out from LinkedIn's sans-serif font |
| Monospace | πΏπππππππ | Mathematical monospace letters and digits | Code, formulas, a prompt you are sharing |
| Strikethrough | PΜΆiΜΆpΜΆeΜΆlΜΆiΜΆnΜΆeΜΆ | Combining long stroke overlay (U+0336) after each character | Before and after: the old way struck through, the new way plain |
| Underline | PΜ²iΜ²pΜ²eΜ²lΜ²iΜ²nΜ²eΜ² | Combining low line (U+0332) after each character | Almost never; it reads like a link |
Accented letters, emoji and punctuation have no styled version, so the tool leaves them as they are. "Plain text" turns any styled letters back into ordinary ones, which is useful when you reuse an old post or move a post into an email, a slide or your blog.
How long can a LinkedIn post be?
LinkedIn's post and share help page says posts "can contain up to 3,000 characters." Other LinkedIn limits that come up when you format posts and ads:
| Where | Limit | Source |
|---|---|---|
| Organic post | Up to 3,000 characters | LinkedIn Help |
| Single image ad, introductory text | 150 characters to avoid truncation, 3,000 maximum | Marketing Solutions Help |
| Document ad, introductory text | 150 characters to avoid shortening, 3,000 maximum | Marketing Solutions Help |
| Video ad, introductory text | 150 characters recommended, 600 maximum | LinkedIn Marketing Solutions |
| Carousel ad, introductory text | 150 characters to avoid truncation on some devices, 255 maximum | LinkedIn Help |
All limits read on LinkedIn's own pages on 3 November 2026.
Two things the 3,000 figure does not tell you. First, LinkedIn does not publish how its counter treats styled letters, which take up two code units each in most software, so the formatter shows a count of what you see and warns you when styled text pushes you near the limit. Second, LinkedIn does not publish where it cuts a post with "...see more". The 150-character advice for ad text is the closest number LinkedIn gives, and it is for ads. For organic posts, plan for the first two lines to carry the post on their own.
Does bold text hurt accessibility or search?
It can, and this is the part most formatter pages skip. The Unicode Standard says its mathematical alphanumeric characters "should not be used to represent styling of nonmathematical text." Screen readers treat them as symbols. Per Axbom, a digital accessibility writer, tested this in 2023 and found screen readers "will most often skip them" or read each one out as a symbol, one character at a time. A buyer who uses a screen reader may hear your hook as silence.
Search has the same problem. A styled letter is a different character from the one people type, so a search for the plain word will not match it. LinkedIn has not published how its own search handles these characters, so assume styled words are invisible to it.
The safe rules:
- Style a few words, not sentences. One bold phrase in the hook or a bold label above each list is plenty.
- Keep these plain: people's names, company and product names, hashtags, links and the topic words you want to be found for.
- Never put the call to action in styled letters. It is the one line every reader needs to hear.
- Use line breaks and lists for structure. They are plain characters and work for everyone, which is why the bullet and number buttons do not use styled letters.
How should a B2B team format a LinkedIn post?
Formatting helps a post get read on a phone; it does not rescue a weak idea. The routine we use when we write posts for founders:
- Make the first two lines work alone. Most readers decide from what shows above "...see more". Put the point there, in plain words, and bold at most one phrase.
- One idea per post. If you need headings, the post probably wants to be a LinkedIn newsletter edition or an article.
- Short lines and white space. Leave a blank line between paragraphs. Use bullets for three to five parallel points and numbers for steps.
- Strikethrough for contrast, sparingly. "Old way" struck through, then the new way in plain text, is the one strikethrough pattern that earns its place.
- Add the visual last. If the post carries an image or a slide document, check the sizes in our LinkedIn image sizes guide so nothing gets cropped.
Illustrative. Brightquay, a fictional payroll software company, has its CFO post about month-end close. The first draft opens with two lines of backstory and styles the whole first paragraph in bold. The edit moves the point to line one ("Payroll errors cost us 11 hours at every month-end"), bolds only "11 hours", turns the fixes into a three-item bullet list and leaves "Brightquay" and the hashtag plain so they stay searchable.

If the hard part is writing three good posts a week, our LinkedIn ghostwriting service drafts posts in each person's own words from short calls and voice notes, and they approve every post before it goes out.
Frequently asked
How do you make text bold on LinkedIn?
LinkedIn posts are plain text, so there is no bold button in the post box. Type or paste your post into the formatter above, select the words you want in bold, click Bold, then copy the result and paste it into LinkedIn. The tool swaps each letter for a bold-looking Unicode character, which LinkedIn shows like any other character.
What is the character limit for a LinkedIn post?
LinkedIn's help center says posts can contain up to 3,000 characters. The counter above shows how many you have used. Styled letters are stored as longer Unicode characters, and LinkedIn does not publish how its counter treats them, so leave a margin if you style a lot of text close to the limit.
Where does LinkedIn cut a post with "see more"?
LinkedIn does not publish an exact cut-off. On most screens only the first two or three lines show before "...see more", and the point moves with the device, the screen width and how many line breaks you use. The preview above cuts at an approximate point, so treat it as a guide and check the real post on your phone.
Is Unicode bold text accessible?
Not fully. The Unicode Standard says its mathematical letters should not be used to style ordinary text, and accessibility writer Per Axbom found that screen readers often skip these characters or read them one symbol at a time. Use styled letters for a few words of emphasis, never for whole sentences, names or calls to action.
Does formatted text show up in LinkedIn search?
Styled letters are different characters from the ones people type, so a search for the plain word may not match them. LinkedIn has not published how its search treats these characters. Keep names, product names, hashtags and the topic words you want to be found for in plain text.
Can I use bold text in my LinkedIn headline or About section?
The characters paste into most LinkedIn text fields because they are ordinary Unicode, but the same accessibility and search costs apply. A headline and About section are where recruiters and buyers search for you, so keep them in plain text and save styling for the occasional post.
