The Small Text Generator turns ordinary text into tiny Unicode "small text" — the miniature, raised, or lowered letters you see in social-media bios, comments, usernames, and captions. Type or paste your text, pick a style, and copy the result. Because these are real Unicode characters (not an image or a special font), they keep working anywhere plain text is allowed: Instagram, TikTok, X/Twitter, Discord, YouTube, and more.
Three small-text styles
- Superscript — raised, above-the-line characters (like footnote markers). Great for exponents, ordinal-looking text, and playful bios. Covers a‑z, A‑Z, 0‑9, and the symbols
+ - = ( ). - Subscript — lowered, below-the-line characters (like chemical formulas, e.g. H₂O). Unicode only defines a subset of subscript letters, so letters without a small form are left unchanged.
- Small Caps — uppercase-shaped letters at lowercase height (ʟɪᴋᴇ ᴛʜɪꜱ). Only lowercase letters are converted; existing capital letters stay full-size, which gives the classic "small caps" look.
How to use it
- Enter your text in the input box.
- Choose Superscript, Subscript, or Small Caps from the style dropdown.
- The converted text appears instantly in the output box.
- Click Copy and paste it wherever you like.
Anything the selected style can't map — for example most punctuation, or a superscript letter that simply doesn't exist in Unicode — passes through untouched, so your text stays readable.
Why do some characters stay normal?
Unicode never defined a complete alphabet for these styles. The subscript block, in particular, is missing many letters (there is no subscript "b", "c", "d", "g", etc.), and a few superscript slots borrow lookalike glyphs from other blocks. This tool uses the closest widely-supported character for each letter and leaves the rest as-is rather than substituting something that renders as a box on most devices.
Will small text work everywhere?
Almost everywhere that accepts plain text, because the output is standard Unicode rather than a custom font. A handful of apps with restricted character sets, or older devices missing certain glyphs, may show a fallback box for rare characters — but the common letters and digits are very broadly supported.
Is my text private?
Yes. The conversion runs entirely in your browser. Nothing you type is uploaded or stored.
