Readability check
Structure only — it can’t judge whether your idea is good.
- ×Hook. Start with a one-line hook that makes people tap “see more”.
- !Length. Very short. Fine for a question post; add context if you want dwell time.
- ✓White space. Paragraphs are short and scannable.
- ✓Sentence length. No sentences yet.
- ✓Hashtags. No hashtags — optional; add 1–3 specific ones if they help discovery.
- !Conversation starter. Close with a specific question to invite comments (not “thoughts?”).
- ✓External link. No outbound link in the post body.
- ✓Styled text. No Unicode styling.
From draft to post in three moves
- Paste your draft. Or start from an example template. It autosaves in your browser.
- Format what matters. Select a phrase and press B or I, pick a bullet style, then “Tidy spacing”. Watch the preview’s fold line move.
- Copy and paste into LinkedIn. Styling is plain Unicode text, so it survives the paste on web, iOS and Android.
Why “bold” on LinkedIn isn’t really bold
LinkedIn posts are plain text. There is no hidden bold tag. What a formatter does is swap each letter for a different character that happens to look bold — the Unicode Consortium added these “mathematical alphanumeric symbols” in 2001 so scientists could write variables like 𝐱 and 𝑥 as distinct symbols. Try it: every letter below gets a new code point.

“Boost” is 5 characters. “𝗕𝗼𝗼𝘀𝘁” costs LinkedIn’s counter 10 — each styled letter sits outside the Basic Multilingual Plane, so it takes two UTF-16 code units.
That swap explains every quirk of styled text. It counts double against the 3,000-character limit, LinkedIn’s search indexes the plain letters rather than the look-alikes, and assistive tech such as VoiceOver or NVDA may announce “mathematical bold capital B” instead of the word. The practical rule: bold three to six words that carry the point, never whole paragraphs, and keep names and keywords plain so people can find you.

Questions people ask
How do I bold text in a LinkedIn post?
LinkedIn’s post composer has no bold button. Paste your post into the formatter above, select the words you want to emphasise and press B. The tool swaps those letters for Unicode “mathematical bold” characters, which look bold anywhere plain text is shown. Copy the post and paste it into LinkedIn.
Is using a LinkedIn text formatter allowed?
Yes. The output is ordinary Unicode text, the same characters you could type with a special keyboard. LinkedIn does not block it. The trade-off is accessibility and search: screen readers may read styled letters one by one and LinkedIn search may not match them, so keep styling to a few key words.
Why does my formatting disappear or show boxes?
Styled letters live in the Mathematical Alphanumeric Symbols block of Unicode. Nearly every modern phone and browser has a font for them, but some older Android devices and a few email clients show empty boxes. Italic and script are the least supported; sans-serif bold is the safest.
How do I keep line breaks in a LinkedIn post?
Line breaks you type in LinkedIn are kept, but some apps collapse double blank lines when you paste. Write or paste here, press “Tidy spacing” to remove stray spaces at line ends, and copy. If a blank line still vanishes, LinkedIn is trimming it — keep one blank line between paragraphs rather than two.
How long can a LinkedIn post be?
A personal or company-page post can be up to 3,000 characters. On phones, roughly the first 140 characters or three lines show before the “…more” link; on desktop it is roughly 210 characters. The counter and preview on this page show you exactly where your post gets cut.
Does this tool store my post?
Your draft is saved only in your own browser (localStorage) so you don’t lose it on refresh. It is never sent to a server unless you press an AI button on one of the AI tools. Use “Forget saved draft” to delete it.
