Subscript Generator
Convert chemical counts, math indices and lowercase words into copy-and-paste Unicode subscript (H₂O · x₁ · ₛᵤᵇₛᶜᵣᵢₚₜ ₁₂₃).

ₛᵤᵇₛᶜᵣᵢₚₜ ₁₂₃
This subscript generator converts plain typing into lowered Unicode characters: all ten subscript digits (₀₁₂₃₄₅₆₇₈₉), five subscript operators (₊₋₌₍₎), and the 17 true low Latin letters standardized by Unicode (with raised stand-ins for the 9 letters Unicode never lowered). Because these symbols are standalone code points rather than <sub> markup, they paste cleanly into spreadsheet headers, Discord display names, Instagram bios, Notion tables and lab notes. Need exponents above the line? Try our superscript generator, grab lone digits and fractions on small numbers copy and paste, or compare all five styles in our small text generator.
How to Use the Subscript Generator
Four practical steps to build chemical counts, indexed math variables and baseline-lowered words — plus how to handle the 9 letters Unicode skipped.
- 1
Type formulas, index labels or short words
Enter your text in the converter box above; clicking inside selects the starter phrase so you can overwrite it right away. Numerals 0 through 9, the five math signs + - = ( ) and lowercase letters map straight to Unicode subscript characters, while spaces, colons and slashes stay untouched — x(n+1) becomes x₍ₙ₊₁₎ when you convert the parenthesized suffix.

Check the 9 letters that Unicode never lowered
Only 17 Latin letters received official low subscript code points across phonetic and mathematical blocks (ₐ ₑ ₕ ᵢ ⱼ ₖ ₗ ₘ ₙ ₒ ₚ ᵣ ₛ ₜ ᵤ ᵥ ₓ). Because b, c, d, f, g, q, w, y and z have no lowered glyph in Unicode, generators substitute raised modifier letters so characters never vanish. Want a completely flat low word? Stick to words built from those 17 letters, such as ₘᵢₙ, ₘₐₓ, ₒₙₗᵢₙₑ or ₛᵢₗₑₙₜ.

Keep chemical element capitals upright when needed
Unicode has zero capital subscript letters, so typing an entire formula like H2O into the full-line box folds uppercase letters into ₕ₂ₒ. Whenever you want upright element symbols such as H₂O, CO₂ or C₆H₁₂O₆, type normal capitals in your note and tap individual lowered digits (₀-₉) from the chart below.

Copy the whole string or single tiles for plain-text apps
Hit Copy next to the output row to grab the converted line, or tap any tile in the reference tables below to copy one character at a time. Because every output symbol is plain text rather than rich formatting, your subscripts stay intact inside Google Sheets headers, Notion comments, Discord names, Instagram bios and Markdown tables.
Unicode Subscript vs. HTML <sub> and Equation Editors
In web pages, LaTeX papers or Word reports, prefer semantic markup — HTML <sub>2</sub>, LaTeX x_{i} or the subscript button — so search engines and screen readers still see ordinary characters and all 26 letters can sit below the line. Turn to Unicode subscript when markup is unavailable: plain-text chat apps, spreadsheet column names, video descriptions, social profiles and flashcards.
Subscript Numbers, Operators & Alphabet Chart
Tap any tile to copy a single lowered digit, operator or letter — handy when keeping chemical symbols like H, C or O capitalized.

Subscript Letters (17 True Low + 9 Raised Stand-Ins)
Amber tiles = raised fallback (no Unicode subscript exists)* Unicode lacks lowered glyphs for b, c, d, f, g, q, w, y and z, so raised modifier letters fill those nine slots. Words using only the 17 true low letters stay completely level along the baseline: min (ₘᵢₙ) · max (ₘₐₓ) · sum (ₛᵤₘ) · init (ᵢₙᵢₜ) · online (ₒₙₗᵢₙₑ) · silent (ₛᵢₗₑₙₜ).

Frequently Asked Questions
Why do 9 letters (b, c, d, f, g, q, w, y, z) float up instead of sitting low?
The Unicode Consortium never encoded a complete a-to-z subscript alphabet. It only added the 17 lowercase subscript letters historically attested in Indo-European linguistics (ᵢ, ᵣ, ᵤ, ᵥ, ⱼ) and mathematical index notation (ₐ, ₑ, ₕ, ₖ, ₗ, ₘ, ₙ, ₒ, ₚ, ₛ, ₜ, ₓ), then closed the door on new Latin sub/superscript additions. Rather than dropping your letters, this tool maps the missing nine onto raised modifier letters — highlighted in amber in the alphabet chart above.
How do I write H₂O or CO₂ without shrinking the capital letters?
Keep H, C and O as regular capital letters and copy only the lowered digits (₂, ₃, ₄) from the Subscript Numbers chart above, or tap one of the ready-made chemistry cards in the examples section. Converting the whole string at once folds capitals to lowercase because Unicode lacks capital subscripts.
Why do subscript numbers (₀-₉) align more evenly than superscript numbers?
All ten subscript digits live side by side in a single Unicode range (U+2080 through U+2089) designed together for the Superscripts and Subscripts block. Superscript digits were split between an older 1980s Latin-1 block (¹²³) and a later range, whereas ₀₁₂₃₄₅₆₇₈₉ share uniform metrics across almost every system font.
Are there capital Unicode subscript letters like A or B?
No. Standard Unicode blocks contain small capitals (ᴀ ʙ ᴄ) that sit on the normal baseline and partial raised capitals, but zero lowered capital Latin letters. Any uppercase input typed into the converter is automatically folded to its lowercase subscript mapping.
Where can I paste Unicode subscript text and where will it be rejected?
Subscript digits and letters work in nearly all free-text fields: Instagram and TikTok bios, captions and comments, Discord display names and messages, X posts, Notion, Obsidian, Airtable and spreadsheet cells. Unique account identifiers — @usernames, email addresses, Xbox gamertags and PlayStation IDs — restrict input to basic ASCII letters and digits.
Should I use Unicode subscript or HTML <sub> in documents and websites?
Use HTML <sub> (or LaTeX / Word formatting) whenever the host platform supports rich text: it lowers every letter cleanly, preserves Ctrl+F search for terms like H2O, and lets assistive readers pronounce formulas naturally. Reserve Unicode subscript for plain-text fields where markup tags would show up literally.
