How it works
Unicode characters, not a font file.
The tool replaces supported characters with visually bold characters from Unicode mathematical alphabets. It creates copyable text, not rich-text formatting, CSS or a font file.
Serif Bold and Sans Bold convert basic Latin AโZ, aโz and 0โ9. Bold Italic, Sans Bold Italic, Bold Script and Bold Fraktur convert basic Latin letters only. Spaces, punctuation, accented letters and other unsupported characters stay as typed.
Keep important text readable
Use bold Unicode for short visual accents rather than entire paragraphs. Some screen readers may announce styled characters individually or skip them, and older devices may show unsupported characters as boxes. Keep links, contact details, instructions and essential keywords in plain text.
FAQ
Questions about bold text
Is bold Unicode text a real font?
No. It is a sequence of styled Unicode characters, not a font file or rich-text formatting.
Can I copy and paste bold text into social media?
Many bio, display-name, caption, post and message fields accept it. Support varies, and username or handle fields may restrict these characters.
Why do numbers stay plain in some bold styles?
Serif Bold and Sans Bold include matching Unicode digits. The other bold styles on this page preserve digits as typed.
Why did some letters stay unchanged?
The six mappings cover basic Latin AโZ and aโz. Accented letters, non-Latin scripts and other unsupported characters remain unchanged instead of being corrupted.
Why does bold text show as boxes?
The device or app may not have a glyph for one or more characters. Try Serif Bold or Sans Bold, or keep essential text plain.
Is bold Unicode accessible?
Not reliably in every screen reader. Use it sparingly and keep important information in ordinary text.
