Subscript and superscript
Use one workspace for lower text like H₂O and raised text like x².

SMALL TEXT, CLEAR RESULT
Convert text without hiding the gaps.
Enter a formula or phrase. Supported characters become true Unicode subscript or superscript forms; everything else remains unchanged and visible.

Every convertible character has a matching form.
Quick examples
Plain-text Unicode does not include a subscript version of every letter. Unsupported characters stay readable instead of being replaced with lookalikes.
DIRECT ANSWER
What is a subscript text generator?
A subscript generator replaces supported letters, numbers and mathematical signs with their small Unicode equivalents, such as H₂O, CO₂ and x₁. The result is plain text, so you can copy and paste it into many apps without opening a formatting toolbar.
USEFUL BY DESIGN
Made for formulas and everyday copy-paste
Useful controls stay close to the text, with no font download or account required.
Formula-friendly symbols
Convert digits, plus, minus, equals and parentheses alongside supported letters.
Visible character coverage
See exactly which letters were converted and which stayed unchanged.
English and Bangla input
Mix Bangla, English, numbers and symbols. Bangla letters remain readable because Unicode has no complete Bangla subscript alphabet.
HOW TO USE IT
Create small numbers and letters in three steps
Enter the original text
Type a formula, label, username or short line in the left box.
Choose its position
Select Subscript for lowered characters or Superscript for raised characters.
Review and copy
Check the coverage note, then copy the plain-text result into the app you need.
ACCURATE OUTPUT
Why are some letters not converted?
Unicode contains subscript digits and a useful but incomplete set of subscript letters. It does not contain a matching lower form for every Latin or Bangla letter. This tool keeps unsupported characters unchanged instead of substituting misleading lookalikes. For a professionally typeset equation or document, use the subscript styling in your editor or mathematical markup.

COMMON QUESTIONS
Subscript generator: common questions
Quick answers about copying, formulas, missing letters, apps, Bangla text and privacy.
How do I make subscript text online?
Type or paste text into the generator, leave Subscript selected, review the result and press Copy result.
Can I copy and paste subscript text?
Yes. The output uses Unicode characters, so it can be pasted into many websites, messages, documents and profile fields. Appearance still depends on the receiving app and font.
Why are some letters left unchanged?
Unicode does not provide a subscript form for every letter. Unsupported characters stay unchanged so the result remains accurate and readable.
Can I create chemistry formulas such as H₂O and CO₂?
Yes. Numbers and many commonly used letters can be converted, making short formulas such as H₂O, CO₂ and H₂SO₄ easy to copy. Check scientific meaning before publishing.
What is the difference between subscript and superscript?
Subscript characters sit lower, as in H₂O. Superscript characters sit higher, as in x². Use the two buttons to switch the output.
Will the text work in Google Docs, PowerPoint or social apps?
Usually, if the app supports the relevant Unicode characters. Some fonts or fields may display them differently, so preview the pasted result before sharing.
Can it convert Bangla letters into subscript?
There is no complete Unicode subscript alphabet for Bangla. Bangla letters therefore remain unchanged, while supported numbers and Latin characters around them can still convert.
Is my text uploaded or saved?
No. Conversion happens in your browser and requires no account. The page does not need to upload the text you enter.
