Calculator by Toolsloft ↗

Turn ordinary text into bold italic Unicode you can paste anywhere, including apps that give you no formatting button such as Instagram bios, Twitter or X posts, TikTok captions, and Discord names. Type once and copy the styled version out. The result is real Unicode, not an image, so it keeps working wherever you paste it.

How this is calculated

Each letter is swapped for its match in the Unicode Mathematical Bold Italic block: capitals from U+1D468 and lowercase from U+1D482. That block is contiguous with no reserved gaps and defines no bold italic digits, so numbers, spaces, punctuation, and any character without a bold italic form are left unchanged. Because the output is standard Unicode, how it renders depends on the font the reader is using.

How to use

  1. Type or paste your text into the input box.
  2. The bold italic Unicode version appears instantly in the output box.
  3. Copy it and paste it into your bio, post, or username.

Examples

  • Word: Hello → 𝑯𝒆𝒍𝒍𝒐
  • With digits kept plain: Bold Italic 123 → 𝑩𝒐𝒍𝒅 𝑰𝒕𝒂𝒍𝒊𝒄 123

FAQ

Is this real bold italic text or an image?
It is real Unicode text, not an image. You can copy and paste it into most apps and websites, and it stays selectable and searchable. It is not the same as the bold italic you get from a formatting toolbar, which is why it works in places that have no such toolbar.
Why did my numbers stay plain?
The Unicode Mathematical Bold Italic block only covers A to Z and a to z. There are no bold italic digits, so 0 to 9, spaces, punctuation, emoji, and accented letters are left exactly as you typed them.
Will it look the same everywhere?
Usually, because these characters are part of the Unicode standard. A few older apps or fonts may show a fallback box for a character they do not include, so paste a short sample where you plan to use it before you commit.
