Twitter / X Text Formatter
Write bold, italic and underlined tweets, add bullet lists, and copy them to X in one click.
X (formerly Twitter) has no bold or italic button for standard posts, so this free Twitter text formatter does it for you. Type or paste your tweet, select words and make them bold, italic, underlined or struck through, switch to fonts like script or monospace, and add bullets, ticks or numbered lists. Tidy the spacing, check the live X post preview and the 280-character counter, then copy your post and paste it straight into X. Your text never leaves your browser, and the tool is free, with no sign-up and no watermark.

How Do You Format Text on Twitter / X?
To format text on X (Twitter), type or paste your post into the editor, select the words you want to change and click B (bold), I (italic), U (underline) or S (strikethrough). Add bullets or numbered lists from the Lists menu, check the preview, then click Copy post and paste it into X. The formatting stays because the tool turns your letters into Unicode characters that X shows on x.com and in the iPhone and Android apps.
Tweets, replies, bios and display names on X only accept plain text, so there is no bold or italic button for standard posts. A Twitter text formatter gets around this by swapping normal letters for look-alike Unicode symbols, such as 𝗛𝗲𝗹𝗹𝗼 for bold. Because they are characters, not styling, they survive copy and paste and appear for everyone who sees your post, on any device.
The formatting happens in your browser, so your tweet is never uploaded or stored. You get a preview card that looks like a real X post, a live character and word count against the standard 280-character limit, and a count of your selected text. Undo, redo, paste from clipboard, a sample post and download as a .txt file are all built in.
Common reasons to format tweets:
- Make the first line of your tweet or thread stand out in a busy timeline.
- Highlight launches, prices, dates or key stats in bold.
- Break threads and longer posts into scannable bullet or numbered lists.
- Add dividers and emojis to separate ideas within a post.
- Style your X bio, display name or pinned post.
- Format replies, quote posts, Community posts and thread hooks.
What each option does:
| Option | What it does | When to use it |
|---|---|---|
| Bold, Italic, Bold italic | Turns selected text into Unicode bold or italic letters. | Hooks, launches, stats and key phrases. |

| Fonts | Sans bold, Sans italic, Monospace, Script, Bold script, Fraktur, Double-struck and Small caps. | Short headings, a name or your bio. Avoid styling a whole tweet. |
| Lists | Bullets, arrows, checkmarks, green ticks, pointers, sparkles, checkboxes, numbers and emoji numbers. | Threads, steps, tips and checklists. |
| Insert | Ready-made dividers and popular emojis. | Separating sections and adding visual cues. |
| Clean up | Clear styling, tidy spacing, space out lines, remove blank lines. | Fixing text pasted from Word, Google Docs or ChatGPT. |
Good to know
- Standard X accounts get 280 characters per post, so put your hook and most important point first.
- X counts emojis and most styled Unicode letters as two characters, so formatted text uses up the limit faster than plain text.
- Styled letters are Unicode symbols, so X search may not match them and screen readers may spell them out. Use them for short highlights, not full posts.
- Decorative fonts like Fraktur or Double-struck may not display on very old phones. Bold and italic work almost everywhere.
- Your text stays on your device. Nothing is uploaded, saved or shared.

| Tips or how-to thread | Bold title | Numbered or emoji numbers | One tip per tweet |
| Product launch or announcement | Bold product name or key news | Green ticks for features | Add a 🚀 or 🔥 emoji |
| Stats or data post | Bold or monospace numbers | Bullets for each stat | Credit the source in plain text |

Writing a tweet that is easy to read:
- Lead with a strong hook in the first line, since that is what people see while scrolling.
- Keep lines short, with a line break between ideas.
- Use bold for a few key words, not whole sentences.
- Use lists for steps, tips or features, and split longer ideas into a thread.
- End with a question or call to action to invite replies and reposts.
After you format your tweet, you can paste the same text into X replies, quote posts, threads, Communities, your bio or your display name. Because the formatting is made of Unicode characters, it also works on Facebook, Instagram, LinkedIn, Threads, Bluesky and other sites that only accept plain text.

What is the character limit for a tweet on X?
Standard X accounts can post up to 280 characters, and X Premium subscribers can write longer posts. The counter under the editor shows your characters and words as you type.
Does styled text count as more characters on X?
Usually, yes. X counts emojis and most Unicode bold, italic and fancy-font letters as two characters each, so a heavily styled tweet reaches the 280-character limit sooner. Style only the words that matter and leave a little room under the counter.
Does bold text affect X search?
Styled letters are different Unicode characters, so X search may not match them. Keep important keywords, names, @mentions and hashtags in plain text.
Is formatted text accessible to screen readers?
Screen readers may read Unicode letters one by one or skip them. Use styled text for short highlights and keep your main message in regular text.
Can I format my X bio, display name or replies?
Yes. Format the text here, copy it and paste it into your X bio, display name, replies, quote posts, threads or Community posts.
How do I remove formatting from text?
