LinkedIn Text Formatter

LinkedIn has no bold button, so this is not bold

LinkedIn posts do not support rich text. There is no bold, italic or underline in the composer, and nothing you paste carries formatting with it. What a LinkedIn font generator does instead is swap each ordinary letter for a different character that happens to look bold or italic.

Those characters come from a Unicode block called Mathematical Alphanumeric Symbols, code points U+1D400 to U+1D7FF. Unicode added the block so mathematicians could denote different notions with different letter styles in the same equation; it holds 997 assigned characters covering styled Latin and Greek letters and digits. A bold A on LinkedIn is not the letter A with weight applied. It is a separate character, mathematical bold capital A, that a font draws heavier.

What that costs you

Because the characters are not real letters, three things break. Screen readers often cannot pronounce them, since they are not semantically bold but a separate code point that only looks bold; a line of them can be read out character by character or skipped. Search sometimes misses them: LinkedIn search and web search engines can fail to match a phrase typed in ordinary letters against the styled version. And copy-paste into tools that expect plain text can produce boxes or question marks.

The practical rule is to style a few words, not paragraphs. One bold line for the hook, a bolded number, an italic aside. The rest of the post should stay in ordinary characters so it is readable by everyone and findable by search.

Which styles this LinkedIn font generator supports

Sixteen fonts: sans-serif bold, italic and bold italic, serif bold, italic and bold italic, monospace, script, gothic, outline, circled, bubble, squared, squared filled, wide and small caps. Most come straight from the Unicode math block; circled and squared letters come from the enclosed alphanumerics, and the squared and bubble sets exist in uppercase only, so lowercase input is shown in capitals. Underline and strikethrough work differently: they place a combining mark after each letter, which most apps render as a line through or under the text, and they can be layered on any font. Combining marks are more fragile across devices than the math letters, so check a strikethrough on mobile before you post it.

Type or paste in the box above, pick a style, copy the result and paste it into the LinkedIn composer. Nothing is sent anywhere; the conversion runs in your browser.

How to bold text on LinkedIn

Type or paste the words you want bold into the box above, choose Bold, and copy the result. Then paste it into the LinkedIn post composer, a comment, your headline or your About section; the bold survives because the characters themselves carry it. The same works for italic and bold italic. To bold only part of a line, convert just those words and paste them in among your normal text.

Because these are different characters rather than formatting, you cannot un-bold them inside LinkedIn. Edit the post, delete the styled words and paste in plain text instead.

Formatting a LinkedIn post so people read it

Styled characters are the smallest part of formatting a post. LinkedIn keeps the line breaks you type in the composer, so short paragraphs and white space do most of the work: a first line that stands on its own, one idea per paragraph, and a list where you would otherwise write a long sentence. Most of the post is hidden behind a see more link in the feed, so whatever earns the click has to sit in the opening lines.

Use the formatter for the one thing you want a scrolling reader to catch: a number, a name, a two-word heading. A post that is mostly bold text is harder to read, harder for screen readers and harder to find in search.

Does formatting change how a post performs?

Not in any way we can measure. Reachium publishes first-party benchmarks on LinkedIn posts, with samples and limitations stated, and the spread in impressions between posts from the same account is wide enough that formatting choices sit well inside the noise. What moves a post is the first line, the topic and the consistency of posting, which is why the tool is free and the scheduling is the product.
