Convert any text to Unicode subscript characters instantly. Type a chemical formula, math expression, or any text — get copy-paste ready ₛᵤᵦₛᶜᵣᵢₚₜ characters that work everywhere.
A subscript generator is a free online tool that converts standard Latin letters and numerals into their Unicode subscript equivalents — characters that sit below the typographic baseline of normal text.
This tool maps each character to its corresponding UTF-8 code point within the Unicode Superscripts and Subscripts block (U+2080–U+209F). These are not styled fonts or HTML entities — they are distinct Unicode glyphs with their own code points in the Basic Multilingual Plane (BMP).
Unlike the HTML <sub> tag which only works in rendered HTML environments,
Unicode subscript characters behave as plain
text — meaning they display correctly anywhere a character set supporting UTF-8 is
used.
No learning curve. Generate Unicode subscript text in seconds on any device.
Enter any text — a chemical formula like H₂SO₄, a mathematical expression, your name, or any plain text. You can also use Chemistry Mode or Math Mode tabs for quick presets, or click the Quick Insert keyboard for individual subscript characters.
Our tool maps each character in real time to its Unicode subscript equivalent. Numbers use code points U+2080–U+2089; letters use the Phonetic Extensions block. Characters without a subscript Unicode equivalent are passed through unchanged.
Click "Copy Subscript Text" and paste into Instagram, Discord, Twitter, Gmail, Google Docs, Slack, Notion, or any text field worldwide. The UTF-8 glyph characters work everywhere plain text is supported — no HTML, no formatting required.
Pro Tip: For full molecular formula notation (H₂O, CO₂, C₆H₁₂O₆, H₂SO₄), use our dedicated Chemistry Subscript Generator — it includes a periodic table quick-insert keyboard and the most common chemical formula templates. For superscript exponents (x², y³), visit our Superscript Generator.
From academic research to social media aesthetics — Unicode subscript text serves a global audience across every cluster.
Write molecular formulas with proper Unicode subscript notation for academic papers, science blogs, and educational content. Convert chemical formulas like H₂O, CO₂, H₂SO₄, NaHCO₃, and C₆H₁₂O₆ without needing LaTeX or Microsoft Word.
Use subscript and small Unicode characters to style your Instagram bio, Discord username, TikTok profile, and Twitter posts. These Unicode font characters paste natively into all social platforms without any app or font changer needed.
Express variable subscripts (xₙ, aₘ, bₖ), tensor notation, and polynomial terms in plain text environments. A fast Unicode alternative to LaTeX for developers, Wikipedia editors, and technical writers working outside HTML environments.
Add footnote markers¹², trademark symbols™, and citation superscripts to plain text emails, legal documents, and business communications. Unicode subscript characters paste into Gmail, Outlook, Google Docs, and PDF tools without formatting loss.
Purpose-built subscript tools for every use case — each with dedicated character keyboards and platform-specific guidance.

Answers to the most common questions about Unicode subscript text, chemical formulas, and platform compatibility.
Type H2O into the input box above. The subscript generator instantly converts the "2" to its Unicode equivalent ₂ (U+2082), producing H₂O. Click Copy and paste it anywhere — works on Windows, Mac, iOS, Android, and all browsers without any special keyboard or software.
Yes — this subscript generator is completely free with no sign-up or download required. Type any chemical formula (H₂O, CO₂, H₂SO₄, C₆H₁₂O₆, NaHCO₃) and it converts the numbers to proper Unicode subscript characters instantly. For a dedicated chemistry experience with a periodic table keyboard, use our Chemistry Subscript Generator.
Subscript digits use these UTF-8 code points in the Superscripts and Subscripts Unicode block: ₀ (U+2080), ₁ (U+2081), ₂ (U+2082), ₃ (U+2083), ₄ (U+2084), ₅ (U+2085), ₆ (U+2086), ₇ (U+2087), ₈ (U+2088), ₉ (U+2089). See our full character map above for the complete list including letters and symbols.
Type CO2 into the tool above. The subscript generator converts "2" to ₂ (U+2082) in real time. Click Copy and paste CO₂ into any platform — email, social media bios, Google Docs, chat apps, or PDF editors. No Microsoft Word, LaTeX, or HTML required.
Unicode provides subscript versions of 14 Latin letters: ₐ(a), ₑ(e), ₒ(o), ₓ(x), ₕ(h), ₖ(k), ₗ(l), ₘ(m), ₙ(n), ₚ(p), ₛ(s), ₜ(t), plus i and u via phonetic blocks. The full 26-letter alphabet is not available in subscript within the standard Unicode BMP. For full-alphabet tiny text, use our Small Text Generator which covers all 26 letters via small caps and phonetic Unicode characters.
HTML <sub> tags only render subscript visually in HTML-rendered
environments — web pages and rich text editors. Unicode subscript characters are actual
UTF-8 code points — distinct glyphs in the character encoding standard — meaning they
display as subscript in any plain text field: social media bios, SMS, email subject lines,
PDF content, and chat apps that do not support HTML markup.
Yes. Generate your subscript formula using this tool, copy it, and paste directly into any Google Slides text box. The Unicode characters paste as plain text and render correctly without using Format → Text → Subscript. This also works in Google Sheets cell content, Google Docs, and Microsoft PowerPoint.
