Bold and italic text generator
LinkedIn, X and Instagram posts have no bold button, so people paste Unicode letters that look bold or italic. Type your text, pick a style and copy the result. Software reads these letters as math symbols, which affects screen readers, search and character counts, so keep them to a word or two.
Try it
Screen readers may read these letters one by one, announce them as math symbols, or skip them. People who use a screen reader may not be able to read your styled text. Keep names, links, hashtags and calls to action in plain text, and style a word or two at most.
How it works
- 1
Type or paste the words you want to style.
- 2
Pick bold or italic.
- 3
Bold swaps letters and digits for look-alikes from Unicode's Mathematical Alphanumeric Symbols block. Italic swaps letters only.
- 4
Copy the result and paste it into your post or bio.
FAQ
- Is this a font?
- No font is involved. Each styled letter is a separate Unicode character from the math symbols block, which is why it pastes anywhere that accepts Unicode text.
- Do styled letters work with screen readers?
- Often badly. A screen reader may spell them out or call them math symbols, so the note above the output asks you to style a word or two at most.
- Do styled letters count more on X?
- Yes. X counts Latin letters as 1 but most other Unicode as 2, so each styled letter uses 2 of your 280.
- Can people search for styled words?
- Search tools that match plain letters may not match them. Keep the words you want found in plain text.
