Processing and privacy: The result is calculated inside your browser and your data is not sent to any server.
How to use it
- Enter text.
- The result appears straight away and updates as you edit.
- Copy the result, or copy a link that keeps the same values to share it.
How it is calculated
Each capital A to Z becomes U+1D400 plus its position (0 to 25), each small a to z becomes U+1D41A plus its position, and each digit 0 to 9 becomes U+1D7CE plus its value.
Example
Result: Styled text: 𝐇𝐢 𝟕; Characters changed: 3.
Hi 7
𝐇𝐢 𝟕
Limits and caveats
- These are Unicode math symbols, not a font: screen readers may read them as symbol names or skip them, and in-app search may not match them.
- Only Latin letters A to Z change (and digits where the style has them); Arabic letters and accented letters such as é stay as typed.
Questions about this tool
Why does the text stay bold after pasting?
The result is not formatting but different characters from the Unicode math block, so any app that supports those characters shows them bold.
Does it work with Arabic text?
No. Unicode has no bold Arabic letters of this kind, so Arabic stays as typed.
Can I use it in my username?
Bios and posts are fine, but many platforms reject these characters in usernames, and people may not find you through search.
