How to use
Type letters or numbers in the input box. Press “Try a sample” to see the results at once.
The list of styles changes as you type. Press “Copy” on the style you want, and the text goes to your clipboard.
Press the star button to pin the styles you use to the top of the list. The pins are kept in this browser only.
The frames (such as 【】, 『』 and ★彡) also work around Japanese text.
To convert back, paste the styled text into the “Convert back” box below.
What it does
Only letters and digits change
Kana, kanji, symbols and emoji stay as they are. Emoji sequences (keycaps, ZWJ family marks) and combining marks are kept whole: the tool works on one visible character (grapheme) at a time.
Built from standard Unicode characters
Bold and italic use the mathematical alphanumeric symbols (from U+1D400). The few holes in those blocks are filled with the Letterlike symbols (such as ℎ and ℬ). These are registered Unicode characters, not images or special fonts.
Three ways to count the same text
The page shows the visible character count, the code point count and the UTF-16 length side by side. A styled letter can look the same but have a longer UTF-16 length, so you can check a service’s length limit.
A warning mark on each style
Each style shows a mark when screen readers may misread it, when search will not find it, or when some devices may not display it.
Use cases
- Make a post heading or a short bio line stand out on Instagram
- Set an English phrase in bold or script in a post on X (formerly Twitter)
- Use circled or double-struck letters in a slide heading
- Create blackboard-style double-struck letters
- Paste letters with a strikethrough or underline as plain text
- Frame a Japanese sentence with 【】 or 『』 to make it stand out

| Converts styled letters and digits back to plain ones (reverse) | Supported | Glyphs NFKC does not map back are restored from a table |
| Restores upside-down text | Partial | The order is not restored, and shapes that look like plain letters (b→q, M→W) do not come back correctly |
| Tells capitals from small letters (parenthesized, black circled and squared styles look the same for both) | Partial | Upper and lower case are not restored |
| Styles shown as emoji (black circled and black squared) | Partial | How they appear depends on the device |
| Changes the font or shape of Japanese (kana and kanji) | Not supported | The font is chosen by the reader’s device |
| Outputs an image (such as PNG) | Not supported | For text as an image, use the text-to-outline tool |
| Makes a character show on a device that lacks its font | Not supported | If it does not show, try another style |
Limits & notes
- Input is up to 1,000 characters. Anything beyond that is not converted (the count is in code points).
- Only letters (A–Z, a–z) and digits (0–9) are converted. Symbols and spaces are not changed.
- Circled digits cover 0–50, black circled 0–10, and parenthesized 1–20, each as one character. Larger numbers stay as digits.
- Some letters have no Unicode counterpart in a style and stay as they are (for example q and x in small caps). Superscript and subscript also miss some letters.
- Conversion runs in your browser.
Privacy & safety
Text you enter is converted in your browser only. Nothing is sent to or stored on a server, and the input is not put in the URL. Pinned styles are saved in this browser’s local storage.
