Why does LinkedIn strip my formatting but keep this?

Because it never sees formatting. The post box accepts plain text and discards style information, which is why pasting from a word processor loses everything. These characters are not style information — they are the text itself, so there is nothing to discard.

Which of the six should I pick?

Sans-serif bold, unless you have a specific reason not to. It matches the typefaces most apps render their own interface in, so the emphasised words look like part of the sentence. Serif bold reads as more formal and slightly out of place on a phone. The script and blackletter versions are decorative rather than emphatic.

Will everyone see it the same way?

Nearly. These come from the Mathematical Alphanumeric Symbols block, which has been supported across Windows, macOS, Android and iOS for many years. A very old device may show empty rectangles, and some apps substitute a fallback face that makes the bold look thinner than intended.

Can I use it in an email subject line?

You can, and it is worth thinking twice. Subject lines are heavily weighted by spam filters, and unusual character ranges are one of the signals they look at. It will also break the recipient's ability to search their inbox for the words in it.

About the Bold Text Generator

Most places you would like to write something in bold will not let you. A LinkedIn post, an Instagram caption, a WhatsApp status, a Google review, a spreadsheet cell, a form field — all plain text, all indifferent to whatever formatting you had in your clipboard. The usual workaround is to shout in capitals, which reads as anger rather than emphasis.

Substituting characters gets round it. This page offers six alphabets that look bold: sans-serif and serif, each with an italic partner, plus a heavy script and a heavy blackletter. Sans-serif bold is the one to reach for by default. It is the closest match to the interface fonts that social platforms actually use, so a phrase in it sits inside your sentence rather than looking like it was pasted from somewhere else, and it is the most widely supported of the six.

Two of the six carry no digits. Unicode gave a full set of bold numerals to the serif and sans-serif alphabets and none to the bold italics, so a year or a price will stay in ordinary type in those rows. The tool tells you when that has happened rather than letting you discover it after posting.

Restraint matters more here than with any of the other styles on this site, for a reason that has nothing to do with taste. Every one of these characters is announced by a screen reader as a mathematical symbol, or skipped completely. A heading of three emphasised words is a small courtesy problem. A whole paragraph is unreadable to somebody using one, and search will not match a single word of it either.

How to use it

1Put your phrase in the box — a few words rather than a paragraph gives the best result.
2Compare the six rows. Sans-serif bold sits most naturally inside ordinary social media text.
3Press Copy on the row you want.
4Paste it into the caption, bio or post. No formatting button is involved at any point.
5Check the note if a number stayed plain: the bold italic alphabets genuinely have no digits.
