Generate Subscript Numbers - Write Numbers in a Subscript Font

A subscript number is a tiny raised eyebrows character that drops below the line to do real work: the 2 in H2O, the index in a_1, the base in log_10, the dimension in a row-plus-column matrix. Typesetting systems draw these as small lowered glyphs, and Unicode obligingly defines a genuine subscript character for every digit 0 through 9. Because they are real characters, they travel as plain text into any field - a chat, a spreadsheet, a document, an equation in a plain-text editor - no styling engine required.

Generate Subscript Numbers converts digits into their Unicode subscript form in one click. Ordinary 0 becomes the lowered 0 (U+2080), 1 becomes the lowered 1 (U+2081), and so on through 9 (U+2089). Subscript signs and parentheses are recognised too, keeping expressions such as log a-b honest and complete. Characters with no standard subscript, like the decimal point, are preserved instead of dropped, so no information is ever lost. Everything runs locally: batch up to 1000 items per run, preview each original beside its subscript twin, and copy or download the whole list as text.

• Real Unicode subscripts: Every digit maps to its official lowered character U+2080-U+2089 - genuine glyphs, not formatting.
• Formulas ready: CO2, H2O and log10 come out with proper lowered digits.
• Signs and parens: Subscript plus, minus, equals and parentheses convert too.
• Value preserved: The lowered 7 in a· stays seven; only the baseline drops.
• Paste anywhere: Output is plain text that keeps its lowered look in any text field.
• Batch mode: Up to 1000 lines, one per line, converted in a single run.
• Side-by-side preview: Original and subscript shown together for checking.
• Free and private: Instant local conversion; nothing is uploaded or logged.

1. Enter your text or numbers - one per line. Plain digits work, and so do snippets like CO2, log10, a1 or 123.
2. Generate - every digit is lowered to its Unicode subscript form immediately.
3. Check the preview pairs - original on the left, subscript on the right.
4. Copy the line you want - or download the full batch as a text file.
5. Paste anywhere - the subscript stays lowered in any plain-text field.

1 - Chemical formulas. Enter H2O and CO2: the digits drop to their subscript forms and the lines read exactly as the chemical notation you expect, ready for a document or a message.

2 - Logarithm bases. Enter log10 and log2: the 10 and 2 descend to the classic lowered base that distinguishes base-10 from base-2 logs at a glance.

3 - Indices and vectors. Type a1, a2 and a3: the small raised digits become true subscript indices, ideal for sequences, tuples and coordinate lists.

4 - Scientific notation text. Enter 10 -3 with a hyphen: the minus and the 3 both lower to their subscript forms, printing the classic small notation used in rates and calibrations.

5 - A batch of labels. Paste H2SO4, C6H12O6 and H2O2, one per line, and receive clean subscript chemistry for a worksheet or article in a single run.

• Genuinely portable: Subscript keeps its lowered position even in plain-text boxes where formatting tools fail.
• Formula-ready: Chemistry, logs and indices that need lowered digits work in seconds.
• Lossless mapping: Characters without a subscript form are preserved, never dropped.
• Batch speed: Hundreds of lines lower at once instead of one by one.
• No plugins: Lowered digits are standard Unicode, readable everywhere text is read.
• Private and free: It all happens in your browser tab; nothing is uploaded or logged.
