Bold and italic text for LinkedIn and X
LinkedIn and X posts have no formatting buttons. This tool turns your text into look-alike Unicode letters that appear bold, italic or monospace anywhere you paste them. Use it for a word or a heading, not a paragraph, and read the note on accessibility first.
Use sparingly
These are look-alike Unicode characters, not real formatting. Screen readers may spell them out or skip them, and searches for the plain words will not find them. Keep them to short headings, never names, hashtags or key terms.

How it works
Unicode, the standard behind all text on the web, includes complete alphabets of mathematical letters in bold, italic, script, double-struck and monospace forms. They were added for formulas, but they look like styled versions of ordinary letters. The formatter swaps each plain letter for its look-alike. Strikethrough and underline work differently: a combining line is added after each character.
Because these are real characters and not formatting, they survive copy and paste into almost any app. That is also where the problems come from.
Accessibility and search: read before you use it
Screen readers do not read styled Unicode as words. Depending on the software, a bold word may be spelled out letter by letter, announced as "mathematical bold capital K" for each letter, or skipped entirely. For someone who relies on a screen reader, a styled sentence can become noise.
Search does not treat them as the same word either. A bold keyword is usually not matched by a search for the plain word, on the network or in search engines, and styled text inside a hashtag breaks the hashtag. Accented letters have no styled versions, so "รฉ" stays plain next to bold letters.
So use it for a short heading or a label, never for whole sentences, names you want to be found by, hashtags or key terms. Plain text with clear line breaks is still the most readable format.
Tips for using styled text well
- Style two or three words at most, such as a section title in a long post.
- Never style your name, your company, a hashtag or a keyword you want people to find.
- Use line breaks and short paragraphs for structure first; styling is the last touch.
- Check the post on a phone: some older devices show empty boxes for these characters.
- If accessibility matters for your audience, and it usually does, skip styling altogether.

How do I write in bold on LinkedIn?
LinkedIn posts have no bold button. Type your text here, copy the bold version and paste it into your post. It is made of look-alike Unicode letters, so keep it short and read the accessibility note.
Does bold text work on X?
Yes, styled Unicode displays on X like anywhere else. Each styled letter counts as one character on most networks, but X counts most of them as two, so a styled post uses up the 280-character limit faster.
Is styled text bad for accessibility?
It can be. Screen readers may spell styled letters out one by one or skip them. Keep it to short headings, and never use it for full sentences or important information.
Why do accented letters stay plain?
Unicode only has styled versions of the 26 basic Latin letters, plus digits for some styles. Letters such as รฉ, รง or รผ pass through unchanged, which can look uneven in French or other languages with accents.
Can I turn styled text back into normal text?
Yes. Paste it into the box and press Remove formatting: every style this tool produces is converted back to plain letters.
Does styled text hurt reach?
No network publishes a rule about it. What is certain is that styled words are not matched by searches for the plain words, so they will not help people find your post.
