Unicode Text Formatter
Bold, italic & script text for social bios.
Your text never leaves your browser
Hides your text behind a privacy screen so no one nearby can read it. Your text stays in the box and keeps counting.These are letter substitutions, not real formatting. Screen readers announce 𝗕 as “mathematical bold capital B” — or skip it — so a whole post in styled text can be unreadable to some of your audience, and platform search often cannot match it. Best used for a word or two, not a paragraph. Paste styled text back in and the Plain text row below converts it into ordinary letters again.

About the Unicode Text Formatter
Unicode Text Formatter turns plain text into bold, italic, script, fraktur, outline, monospace, small caps and more, then lets you copy whichever style you like. Every style is previewed against your own text at once, so you can compare them at a glance instead of cycling through a dropdown.
It exists because LinkedIn, Instagram, X, Facebook and WhatsApp all strip HTML from posts and bios — there is no bold button. What a social media text formatter actually does is swap each letter for a different Unicode character that happens to be drawn in a bolder or more slanted shape, which those platforms pass through untouched. That is why the result survives a paste into a LinkedIn headline when real formatting does not.
The conversion runs both ways. Paste text that is already styled and the Plain text row hands it back as ordinary letters — useful when you have inherited a bio full of substituted glyphs, or when you need text that search and screen readers can actually read. Your text never leaves your browser — everything is computed locally.
Common uses
- Making a line of a LinkedIn headline or About section stand out.
- Styling an Instagram or X bio, where no formatting controls exist.
- Adding emphasis to a WhatsApp or Facebook post beyond its own markup.
- Stripping substituted glyphs back to plain, searchable text.
Frequently asked questions
Is this real bold text?
No, and the distinction matters. Your text is not being formatted — each letter is swapped for a different Unicode character that is drawn in a bolder shape. "𝗕" is not a bold B; it is MATHEMATICAL SANS-SERIF BOLD CAPITAL B, a separate character that exists so mathematicians can write vector notation. Platforms pass it through because, to them, it is just another letter.
Will it work on LinkedIn, Instagram, X, Facebook and WhatsApp?
Yes — on all of them, in posts, headlines, bios and comments, because the styling travels in the characters themselves rather than in any markup the platform could strip. The same text also works in Google Docs, Slack, Discord, email subject lines and most form fields.
Should I use it? What is the accessibility cost?
Use it for a word or two, not a paragraph. A screen reader reads these characters by their Unicode names or skips them entirely, so "𝗛𝗲𝗹𝗹𝗼" can be announced as five mathematical symbols rather than as "Hello" — a heading in styled text may be unreadable to part of your audience. Platform search and hashtags often fail to match them too, so a styled keyword can make a post harder to find. The tool does the job either way; the trade-off is worth making deliberately.
Why do some characters show as empty boxes?
A box means the device you are viewing on has no font covering that character. Bold and italic are widely supported; fraktur, script and outline are less so on older Android builds and some smart TVs. Preview on a phone before publishing, and prefer the styles nearer the top of the list if the audience is broad. This tool never emits an unassigned code point — the boxes some other generators produce for letters like ℌ and ℝ come from a real bug that is avoided here.
Can I convert styled text back to plain?
Yes. Paste it into the box and copy the Plain text row at the top of the list, which strips every style this tool can produce — including the strikethrough and underline marks — and returns ordinary letters. You can also paste one style and copy another: the text is normalised before restyling, so switching from bold to italic works in one step.
How do strikethrough and underline work?
Those two are not substituted letters. They are combining marks — invisible characters that attach to the letter before them and draw a line through or under it — so they stack on top of whichever style you pick. They are offered as a choice of one because applying both to the same character renders as a smear in most fonts.
Does styled text affect SEO?
On a web page, yes, and badly — a search engine indexes the characters it is given, so a heading in substituted glyphs is indexed as gibberish and matches nothing anyone types. Never use it in page titles, headings or body copy. Social bios are lower stakes, but the same limitation applies to the platform’s own search.
