Instagram, X and TikTok have no bold button, so here the bold is built into the letters. Bold is already on: just type or paste, then copy. To keep some words plain, switch Bold off while you write them.
On a keyboard, Ctrl+B (Cmd+B on a Mac) does the same as the Bold button.
A normal bold button only exists inside the app that drew it. Copy bold text out of Word, paste it into Instagram, and plain letters arrive.
This works differently. Unicode, the standard every phone and computer uses to store text, contains complete bold alphabets that were added for maths formulas. Here the bold is part of each letter, not a setting on top, so it goes wherever the letters go. Nobody installs anything, neither you nor the people reading it.
Paste the bold text into the box and press Make it normal. It works on bold made anywhere, not only here, and it also undoes italic, script, gothic and monospace letters, because every one of them maps back to an ordinary letter.
Select a part first and only that part changes. Handy for a bio someone else wrote in bold, a quote you want to search for, or a name a form refuses to accept.
A separate box for comparing. Type a word or two and every bold style shows it at once, each with its own copy button. The first four look right on any phone or computer made in the last ten years. Bold Script and Bold Gothic rely on fonts some older devices lack, and those show an empty box for each letter.
| Style | Looks like | Renders on | Use it for | Copy |
|---|---|---|---|---|
| Bold | 𝗕𝗼𝗹𝗱 𝗧𝗲𝘅𝘁 𝟭𝟮𝟯 | Any device | The default. Sans-serif, so it matches the app you paste it into. One of two styles with bold digits. | |
| Serif Bold | 𝐁𝐨𝐥𝐝 𝐓𝐞𝐱𝐭 𝟏𝟐𝟑 | Any device | Bold with serifs, and bold digits too. Reads like a printed headline; good for a name or a title. | |
| Bold Italic | 𝘽𝙤𝙡𝙙 𝙏𝙚𝙭𝙩 123 | Any device | Bold and slanted, for a single phrase. This style has no digits, so numbers stay regular. | |
| Serif Bold Italic | 𝑩𝒐𝒍𝒅 𝑻𝒆𝒙𝒕 123 | Any device | Bold italic with serifs, the most formal of the six. Numbers stay regular. | |
| Bold Script | 𝓑𝓸𝓵𝓭 𝓣𝓮𝔁𝓽 123 | Most devices | Bold handwriting. Thick enough to stay readable in small print, which thin script is not. | |
| Bold Gothic | 𝕭𝖔𝖑𝖉 𝕿𝖊𝖝𝖙 123 | Most devices | Blackletter, the Old English look, in its heavy cut. Gamer tags, band names, tattoo sketches. |
The letters paste into nearly any text field. Usernames and handles are the exception, and several chat apps already have real bold. Where real bold exists, use it: it stays searchable, and screen readers read it as words.
Works in your bio, name, captions and comments.
Not in your @username. Not in hashtags either, which only link when written in plain letters. For captions whose blank lines vanish on posting, use the Instagram line break generator.
Works in posts, replies, your display name and bio.
Each bold letter counts as two characters towards the limit, so a bold post runs out of room twice as fast. Your @handle stays plain.
Works in your bio, captions and comments.
Your @username only takes plain letters, numbers, underscores and full stops.
In messages, type **bold** for real bold instead.
Use these letters where markdown does nothing: your nickname, your profile and server names.
All three have real bold: wrap the word in single asterisks, *like this*.
Save the bold letters for places with no formatting of their own.
Works in posts, comments and your bio, but not in page or profile names.
The Facebook font generator previews your text as a post before you paste it.
Works in posts, comments, your headline and About section.
Recruiters search headlines, and a bold word no longer matches what they type. The LinkedIn text formatter also marks where “see more” cuts your post.
Use Ctrl+B. These have real bold, and bold Unicode letters break spellcheck, find and search in them.
No platform forbids them. These are the trade-offs, and the reason a bold word or line works better than a bold paragraph.
Assistive software does not know these are letters. Depending on the program, a bold name is spelled out one character at a time, announced as a string of “mathematical bold” symbols, or dropped. Keep bold to a word or a line, and never let it carry the only copy of something important.
Searching for “sale” will not find 𝘀𝗮𝗹𝗲, on Instagram, on X or on Google. Your name, your brand and your product words belong in plain letters.
Bold, Serif Bold and both bold italics are in the fonts of every current phone and computer. Bold Script and Bold Gothic are missing on some older Android phones and Windows PCs, which draw a box per letter.
Every bold letter is stored as two code units, and some counters, X included, count it as two characters. The character limits page has the caps for each platform.
Want cursive, bubble letters or upside-down text instead? The full style table has all 17 Unicode styles, and the bubble text generator and upside down text generator do one style each.
Type or paste it into the box at the top, where Bold is already switched on, and copy. The bold is built into the letters, which come from the bold alphabets in Unicode, so it is still there when you paste into an Instagram bio, a post on X or a TikTok caption.
Switch Bold off and write your text, then select the word and press Bold, or Ctrl+B (Cmd+B on a Mac). Or leave Bold on and switch it off and on around the plain words as you type. On a phone, long-press the word to select it, then tap Bold. The copy button takes the whole text at once.
Paste it into the editor and press Make it normal. It turns bold, italic, script, gothic and monospace letters from any generator back into the ordinary letters they stand for. Select part of the text first to change only that part.
The bold alphabets only cover A to Z, a to z and, in two styles, the digits. Letters like æ, ø and ß have no bold version, so they stay as they are, and the editor says when that happened. Accented letters do work: é becomes a bold e with the accent kept on top. Punctuation never changes.
No. Nothing is installed on your device or on the reader's. The bold letters are ordinary Unicode characters, like an emoji, so they show up for anyone whose phone or computer can display them. If you want a bold font file for design work, that is a different thing from this.
In your bio and your name, yes. Your @username is restricted to plain letters, numbers, full stops and underscores, so bold letters are rejected there. Hashtags also need plain letters to stay clickable.
Each bold letter is stored as two code units instead of one, and some platforms count it that way. X counts every bold letter as two characters, so a bold post fills up twice as fast as a plain one.
The phone or computer reading it lacks a font that includes those characters, so it draws a placeholder. Bold, Serif Bold and the two bold italics are covered almost everywhere. Bold Script and Bold Gothic are the two to avoid if your readers may be on old Android phones or Windows PCs.
Use their own formatting, which is real bold: two asterisks on each side on Discord, one on each side in WhatsApp, Messenger and Slack. Save the bold Unicode letters for places those markers do nothing, such as a Discord nickname or server name.
It can be. Screen readers do not see letters but maths symbols, so a bold word may be spelled out character by character or left out. A bold word or heading is a small cost. A whole bio in bold may tell a blind visitor nothing at all.
