Threads Text Formatter
Paste your post, select the words you want to stand out and click a style. Threads has no formatting buttons of its own, so this tool converts your text to Unicode characters that look bold or italic and paste into Threads 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 Threads, but screen readers may read them letter by letter, so keep emphasis to a few words.
How to format text on Threads

- Select a word, a sentence or a whole line. With nothing selected, the style applies to everything.

Formatting tips for Threads
- Threads shows the first few lines and folds the rest.
- 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 Threads search does not match them: keep any keyword you want found in plain text.
- The post limit is 500 characters.

Frequently asked questions
Is the Threads 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 Threads?
Threads 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 Threads post?
Threads shows the first few lines and folds the rest. 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.
