How do I make bold text on Twitter/X?

Twitter has no bold button. Paste your text above, click Copy on the Bold style, then paste it into your tweet composer or bio. The tool converts your letters to Unicode bold characters that Twitter displays as bold.

What styles are supported?

Bold, italic, bold italic, sans-serif bold and italic, script, bold script, fraktur, double-struck, monospace, underline, strikethrough, and double underline — plus one-click bullet points (•, →, ✓, ★, ✦).

Does styled text count toward the 280-character limit?

Yes, and more than expected — Unicode glyphs are multi-byte, so formatted text eats into your 280-char limit faster than plain text. Check your character count in the tweet composer after pasting.

Will hashtags and mentions still work?

Yes — as long as you don't style them. Keep #hashtags and @mentions as plain text; styling them doesn't break them on X the same way it does on Instagram, but it does make them harder to read.

Is the text searchable on X?

No. Unicode-formatted text is not indexed by X search, so don't format keywords you want people to find. Use it for visual hooks at the start of a post, not for searchable terms.

Twitter/X Text Formatter

Twitter and X have no built-in text formatting, but you can paste Unicode Mathematical Alphanumeric Symbols to make text appear bold, italic, bold italic, script, fraktur, monospace, underlined, and more — in tweets, replies, and your bio. Type your text and every style updates live; click copy and paste it directly into the tweet composer or your X bio. Runs entirely in your browser — free, instant, no signup, no watermark, no usage cap. Important: styled text counts toward the 280-character limit, is not indexed by X search, and is not read correctly by screen-readers, so use it for short attention-grabbing hooks rather than whole tweets.

A few things to know before posting:

Counts toward 280 chars: Styled glyphs are multi-byte, so formatted text uses up your character limit faster than it looks.
Not indexed by X search: Unicode text won't appear in keyword searches — keep hashtags and searchable terms as plain text.
Screen-reader unfriendly: Assistive tech reads these as Unicode names, not styled words. Use sparingly — one or two words max.
Old clients may show boxes: Very outdated third-party Twitter clients may not render the glyphs.
