Text styles

  • Bold

    Sans-serif bold, the most common pick for LinkedIn and Instagram.

    𝗧𝘆𝗽𝗲 𝗼𝗿 𝗽𝗮𝘀𝘁𝗲 𝘆𝗼𝘂𝗿 𝘁𝗲𝘅𝘁 𝗵𝗲𝗿𝗲

  • Italic

    Sans-serif italic. No italic digits exist, so numbers stay as typed.

    𝘛𝘺𝘱𝘦 𝘰𝘳 𝘱𝘢𝘴𝘵𝘦 𝘺𝘰𝘶𝘳 𝘵𝘦𝘹𝘵 𝘩𝘦𝘳𝘦

  • Bold italic

    Sans-serif bold italic. Digits stay as typed.

    𝙏𝙮𝙥𝙚 𝙤𝙧 𝙥𝙖𝙨𝙩𝙚 𝙮𝙤𝙪𝙧 𝙩𝙚𝙭𝙩 𝙝𝙚𝙧𝙚

  • Sans

    Regular sans-serif symbols; looks like plain text in a slightly different face.

    𝖳𝗒𝗉𝖾 𝗈𝗋 𝗉𝖺𝗌𝗍𝖾 𝗒𝗈𝗎𝗋 𝗍𝖾𝗑𝗍 𝗁𝖾𝗋𝖾

  • Bold serif

    Serif bold with its own digits.

    𝐓𝐲𝐩𝐞 𝐨𝐫 𝐩𝐚𝐬𝐭𝐞 𝐲𝐨𝐮𝐫 𝐭𝐞𝐱𝐭 𝐡𝐞𝐫𝐞

  • Italic serif

    Serif italic. The lowercase h is the Planck constant symbol, which is why it is listed explicitly.

    𝑇𝑦𝑝𝑒 𝑜𝑟 𝑝𝑎𝑠𝑡𝑒 𝑦𝑜𝑢𝑟 𝑡𝑒𝑥𝑡 ℎ𝑒𝑟𝑒

  • Bold italic serif

    Serif bold italic. Digits stay as typed.

    𝑻𝒚𝒑𝒆 𝒐𝒓 𝒑𝒂𝒔𝒕𝒆 𝒚𝒐𝒖𝒓 𝒕𝒆𝒙𝒕 𝒉𝒆𝒓𝒆

  • Monospace

    Typewriter look with its own digits; handy for code-like snippets.

    𝚃𝚢𝚙𝚎 𝚘𝚛 𝚙𝚊𝚜𝚝𝚎 𝚢𝚘𝚞𝚛 𝚝𝚎𝚡𝚝 𝚑𝚎𝚛𝚎

  • Script

    Calligraphic letters. Eleven of them come from the Letterlike Symbols block.

    𝒯𝓎𝓅ℯ ℴ𝓇 𝓅𝒶𝓈𝓉ℯ 𝓎ℴ𝓊𝓇 𝓉ℯ𝓍𝓉 𝒽ℯ𝓇ℯ

  • Bold script

    Heavier calligraphic letters, a complete set.

    𝓣𝔂𝓹𝓮 𝓸𝓻 𝓹𝓪𝓼𝓽𝓮 𝔂𝓸𝓾𝓻 𝓽𝓮𝔁𝓽 𝓱𝓮𝓻𝓮

  • Double-struck

    Outlined letters and digits; C, H, N, P, Q, R and Z are the number-set symbols.

    𝕋𝕪𝕡𝕖 𝕠𝕣 𝕡𝕒𝕤𝕥𝕖 𝕪𝕠𝕦𝕣 𝕥𝕖𝕩𝕥 𝕙𝕖𝕣𝕖

  • Fraktur

    Blackletter. C, H, I, R and Z come from the Letterlike Symbols block.

    𝔗𝔶𝔭𝔢 𝔬𝔯 𝔭𝔞𝔰𝔱𝔢 𝔶𝔬𝔲𝔯 𝔱𝔢𝔵𝔱 𝔥𝔢𝔯𝔢

  • Bold fraktur

    Heavier blackletter, a complete set.

    𝕿𝖞𝖕𝖊 𝖔𝖗 𝖕𝖆𝖘𝖙𝖊 𝖞𝖔𝖚𝖗 𝖙𝖊𝖝𝖙 𝖍𝖊𝖗𝖊

  • Strikethrough

    Adds a combining long stroke (U+0336) after each character except spaces; works on any letter, not only A to Z.

    T̶y̶p̶e̶ o̶r̶ p̶a̶s̶t̶e̶ y̶o̶u̶r̶ t̶e̶x̶t̶ h̶e̶r̶e̶

  • Underline

    Adds a combining low line (U+0332) after each character except spaces.

    T̲y̲p̲e̲ o̲r̲ p̲a̲s̲t̲e̲ y̲o̲u̲r̲ t̲e̲x̲t̲ h̲e̲r̲e̲

These are Unicode symbols, not a font or native formatting. Screen readers may read them letter by letter or skip them, and search does not match them to the plain words. Use them for a short highlight, not for whole posts.

How to use

  1. 01

    Type or paste your text

    The previews update as you type. Spaces, line breaks and emoji are kept exactly where you put them.
  2. 02

    Pick a style

    Bold sans is the safest choice for LinkedIn and Instagram. Serif, script and fraktur render less consistently on older phones.
  3. 03

    Copy and paste

    Each style has its own copy button. Paste into the platform's composer like any other text. You do not need to install an app or a font.
  4. 04

    Check the result where it will be read

    Open the draft on a phone and in a browser before publishing. If a letter shows as a box, that device lacks a glyph for it.

Why does the text look bold without a bold button?

Unicode has a Mathematical Alphanumeric Symbols block with bold, italic, script, fraktur, double-struck, sans-serif and monospace versions of the Latin alphabet, meant for formulas. Platforms that strip formatting still accept these characters because to them they are ordinary letters. The tool replaces each ASCII letter with its counterpart from an explicit table; a few letters such as the italic h or the script B, E, F, H, I, L, M and R live in the older Letterlike Symbols block, which is why a simple code point offset would get them wrong.

Does bold Unicode text hurt accessibility and reach?

A screen reader reads 𝗕𝗼𝗹𝗱 as "mathematical bold capital b, mathematical bold small o" or as nothing at all, depending on the voice. Hashtags and keywords in styled text do not count as the plain word for search or for platform algorithms. Keep styled text to a headline or a single emphasised phrase and leave the body of the post plain.

How do you use bold text on LinkedIn, Instagram and X?

Type the phrase, copy the Bold row and paste it into the post, caption, bio or profile field. It works where the composer has no bold button, such as LinkedIn feed posts and Instagram captions and bios, because the styled letters are ordinary Unicode characters. Use it for a headline or one emphasised phrase and keep hashtags, names and keywords plain, since search on these platforms matches the plain spelling. For styling a whole LinkedIn post with lists and undo, the LinkedIn text formatter applies the same styles to a selection.

Limitations

  • Only A to Z, a to z and 0 to 9 change. Accented letters (ą, ę, ł, é, ñ), Cyrillic, Greek, CJK and emoji have no styled Unicode counterparts and stay as typed.
  • Italic, bold italic, script and fraktur styles have no digits in Unicode, so numbers stay plain in those styles.
  • Styled text is a sequence of mathematical symbols. Screen readers may spell it out or skip it, search engines and platform search do not match it to the plain words, and it cannot be edited with the platform's own bold button.
  • Some apps and older devices lack glyphs for parts of the Mathematical Alphanumeric block and show boxes instead.
  • Strikethrough and underline add a combining mark after every character, which nearly doubles the character count on platforms that count code points (spaces and line breaks get no mark).

FAQ

Does this work in an Instagram or TikTok bio?

Yes. The bio field accepts any Unicode text, so the styled letters paste in like normal characters. The bio limit still applies; paste the result into the Instagram character counter to see how much of it the styled text uses.

Why do some letters stay normal after converting?

Unicode only has styled versions of the basic Latin alphabet and digits. Letters with diacritics such as ą, ł, é or ü, other scripts and emoji have no bold or italic forms, so the tool leaves them unchanged.

Is the bold text searchable or good for SEO?

No. Search engines and in-app search see different characters, so a styled keyword is not matched to the plain word. Keep anything you want found, including hashtags, in plain text.

Why does the character count double for strikethrough?

Strikethrough and underline are made with a combining mark placed after every character except spaces and line breaks. Platforms that count code points see two characters for each marked one, so a 100-character sentence with 15 spaces grows to about 185.

Can I turn the styled text back into normal text?

The LinkedIn text formatter on this site has a plain text action that reverses every style this generator produces, including strikethrough and underline.

Is my text sent to a server?

No. The conversion runs in your browser and nothing you type leaves the page.
