X Text Formatter
Paste your post, select the words you want to stand out and click a style. X has no formatting buttons of its own, so this tool converts your text to Unicode characters that look bold or italic and paste into X unchanged.
Select part of your text to style only that part. With nothing selected, the style applies to the whole post. Styled letters are Unicode characters, so they survive pasting into X (Twitter), but screen readers may read them letter by letter, so keep emphasis to a few words.
How to format text on X (Twitter)
- Paste or type your post in the box above.
- Select a word, a sentence or a whole line. With nothing selected, the style applies to everything.
- Click Bold, Italic, Underline or one of the other styles.
- Add bullets with the •, → or ✔ buttons: they prefix every selected line.
- Copy the result and paste it into X, or send it straight to the scheduler.
Does bold text work on X (Twitter)?
X has no formatting for free accounts; bold and italic are a Premium feature, and even then they do not show for everyone. Unicode characters are how most formatted posts on X are made. They count as two characters each in the 280 limit, so use them for a few words, not a paragraph.
X has no formatting on free accounts. Bold and italic exist only for Premium subscribers, so Unicode text is how most people add emphasis.
Formatting tips for X
- Line breaks count as one character each.
- Use bold for the first line and for one phrase per paragraph. Whole paragraphs in bold read as shouting and are skipped.
- Styled letters are Unicode symbols. Screen readers spell them out one at a time, and X search does not match them: keep any keyword you want found in plain text.
- The post limit is 280 characters, and every styled letter counts as two.

Frequently asked questions
Is the X text formatter free?
Yes. It runs entirely in your browser, there is no signup and nothing you type is sent anywhere.
Why does the bold text look different on some phones?
The styled characters come from the Unicode "Mathematical Alphanumeric Symbols" block. Every modern phone and browser has them, but older Android keyboards and some email clients render them in a slightly different typeface.
Will formatted text hurt my reach on X?
X does not penalise Unicode characters. What can hurt is readability: a post that is mostly styled text gets skipped, and styled keywords are invisible to search. Use it for emphasis, not decoration.
Can I add bullet points to a X post?
Line breaks count as one character each. The bullet buttons above add the symbol to the start of each selected line.
Can I undo the formatting?
Select the text and click "Clear formatting": it converts styled characters back to plain letters.
