LinkedIn posts have no bold or italic button. To bold text on LinkedIn, type or paste your post in the editor above, select the words and press Bold (or Cmd/Ctrl+B), then copy the post and paste it into LinkedIn. The formatter swaps those letters for Unicode bold characters, which display the same on desktop, iPhone and Android. The preview shows where LinkedIn cuts your post with “…more”, and the counter checks the 3,000-character limit.
Formatting gets a post read; what you post decides whether people follow you. Our playbook on growing on LinkedIn with AI covers the rest of the system, and hook copywriting explains how to write the line that sits above “…more”. No draft yet? Start one with the LinkedIn post generator, or test openers with the hook generator.
Why use this tool?
- Formatting where LinkedIn has none: bold, italic, bold italic, underline, strikethrough, monospace and eight more styles, applied only to the words you select.
- See the cut before you post: the preview estimates where “…more” falls on mobile and on desktop, so your hook is not split mid-sentence.
- Paste from ChatGPT, Claude or Notion: Markdown such as **bold**, *italic*, # headings and - lists is converted, instead of showing up as asterisks on LinkedIn.
- Accents handled: French, Spanish or German posts keep their é, ç or ü in bold (the accent is added as a combining mark); accented capitals stay regular so the accent never disappears.
- Spacing that survives publishing: an option keeps your empty lines when LinkedIn would squeeze them.
What is the LinkedIn Text Formatter?
A LinkedIn text formatter converts ordinary letters into styled Unicode characters (𝗯𝗼𝗹𝗱, 𝘪𝘵𝘢𝘭𝘪𝘤, 𝚖𝚘𝚗𝚘𝚜𝚙𝚊𝚌𝚎 and more) and adds underline or strikethrough marks. They are characters, not formatting, so they survive a paste into fields that only accept plain text: LinkedIn posts, comments, your headline and your About section. LinkedIn articles and newsletters are the exception: their editor has real bold and italic, so you don’t need a formatter there.
How it works
- 1
Write or paste your post
Type in the editor or paste a draft. Markdown from an AI assistant is detected and converted in one click.
- 2
Select words and style them
Use the toolbar or the shortcuts (Cmd/Ctrl+B bold, Cmd/Ctrl+I italic, Cmd/Ctrl+U underline). Click again to remove a style. Bullets and numbered lists apply to the selected lines.
- 3
Check the preview
Switch between mobile and desktop to see where “…more” cuts the post and keep your hook above it. The counter tracks the 3,000-character limit.
- 4
Copy and paste into LinkedIn
Press Copy post and paste it into the LinkedIn composer, a comment or your profile. Your draft stays in this browser until you clear it.
What a great result includes
- A hook that fits above “…more”: about 140 characters on mobile, about 210 on desktop.
- Short paragraphs with an empty line between them, so the post reads well on a phone.
- Bold on one to three phrases at most: the hook or the key idea, not whole paragraphs.
- Bullets or numbers for steps and lists, one idea per line.
- Keywords, names and hashtags in plain text, so LinkedIn search and screen readers read them.
- A closing question or call to action in plain text.

Frequently asked questions
How do I bold text in a LinkedIn post?+
LinkedIn’s post editor has no bold button. Write your post in the formatter above, select the words, press Bold (or Cmd/Ctrl+B), then copy the post and paste it into LinkedIn. The bold letters are Unicode characters, so they stay bold on every device.
How can I format text on LinkedIn?+
Posts, comments, your headline, About section and experience descriptions accept plain text only: line breaks and emoji work, bold and italic need Unicode characters like the ones this formatter produces, and lists are plain characters (•, →, 1.) at the start of each line. LinkedIn articles and newsletters are the exception: their editor has real bold, italic, underline, headings and lists.
Can I highlight text in a LinkedIn post?+
No, LinkedIn has no highlight or text color. To make a phrase stand out, set it in bold, give it a line of its own, or start the line with a symbol such as → or ✅.
How do I italicize or underline text on LinkedIn?+
Select the words and press Italic (Cmd/Ctrl+I) or Underline (Cmd/Ctrl+U) in the formatter, then copy the post. Italic uses Unicode italic letters; underline and strikethrough add a mark under or through each character, which some older fonts draw less neatly than bold.
How do I bold text in a LinkedIn post on iPhone or Android?+
Open this page in your phone’s browser, write or paste the post, select the words and tap Bold, then Copy post and paste it into the LinkedIn app. The characters display the same in the iOS and Android apps.
Can I use bold text in my LinkedIn headline, About section or experience?+
Yes, the same Unicode text pastes into those fields. Keep the words recruiters search for (job titles, skills) in plain text: LinkedIn search does not read 𝗠𝗮𝗿𝗸𝗲𝘁𝗶𝗻𝗴 as the word Marketing.
Why do accented letters look different in bold?+
Unicode’s bold and italic alphabets only cover A to Z, a to z and digits: there is no bold é or ç. The formatter writes the bold base letter followed by the accent as a combining mark, which common fonts draw correctly on lowercase letters. Accented capitals (É, À) stay regular, because the accent does not display above a styled capital in common system fonts. To keep every accented letter unstyled, choose “Leave them plain”.
How many characters show before “see more” on LinkedIn?+
LinkedIn does not publish the number. Guides that measure it report about 210 characters on desktop and about 140 on mobile, and no more than about 3 lines, an empty line counting as one. The preview above applies those estimates: treat it as a guide and keep your hook short.
Does bold text count toward the 3,000-character limit?+
Yes. A LinkedIn post holds up to 3,000 characters, and each styled letter is stored as two code units, so it can count double. The counter above counts styled letters as 2 to stay on the safe side.
Is bold Unicode text bad for accessibility or reach?+
Screen readers may spell styled letters one by one or skip them, so use them on a few words, not whole paragraphs. LinkedIn has not said that styled characters change how a post is distributed; what is certain is that search and assistive tools read them as different characters.
