Bold Unicode text
Mathematical bold letters give a name or a short heading more weight. Copy the result from the page; the words you type are not uploaded.
This is a Unicode character conversion, not a font file. Apps differ in which characters they can show.
Up to 2000 characters. The conversion stays in this browser.

What bold means here
These letters come from the Mathematical Bold range. They are not the same as CSS font-weight, and a text editor's Bold button will not produce them. Search and a screen reader may treat them as separate characters from A to Z.
Where a heavier letter helps
Use it for a display name or the first line of a bio, where a short word should stand apart from the plain text around it. It is a poor fit for a password, an email address, or a full paragraph, because many fields accept only basic Latin letters.
Examples
- Hello → 𝐇𝐞𝐥𝐥𝐨 (Mathematical bold)
- Nova → 𝐍𝐨𝐯𝐚 (Mathematical bold name)
Questions
Will every site show this as bold?
Only if that site's font includes the mathematical bold glyphs. Otherwise you may see boxes or the plain missing-glyph mark.
Can I turn the result back into plain letters?
Yes. The plain-text control on the page maps styled letters it knows back to basic Latin. Characters it does not map stay as they are.
