Case Converter
Paste your text, pick a case, and convert instantly. Useful for headlines, code identifiers, and cleaning up text that was typed with caps lock stuck on.
How to use the case converter
Paste or type your text into the box, then click a case button. The text in the box is converted immediately and in place, so you can keep clicking different case buttons to compare, or copy the result straight to your clipboard.
What each case does
UPPERCASE / lowercase
Converts every letter to all caps or all lowercase — handy for constants in code, or for normalizing text pasted from inconsistent sources.
Title Case
Capitalizes the first letter of every word, following common headline style. Useful for blog post titles and page headings.
Sentence case
Capitalizes only the first letter of each sentence, the rest lowercase — the standard style for regular prose.
camelCase & aLtErNaTiNg
camelCase joins words together for use as programming variable names. Alternating case flips upper/lower letter by letter, often used for sarcastic emphasis online ("mOcKiNg sPoNgEbOb" style text).
Frequently asked questions
Does Title Case capitalize small words like "the" or "and"?
This tool capitalizes every word for simplicity and predictability. If you need strict headline-style rules that lowercase minor words (a, the, of, and), you'll want to adjust those manually afterward.
Will converting case affect punctuation or numbers?
No. Only alphabetic characters are affected; numbers, punctuation and symbols are left exactly as they are.
Can I undo a conversion?
Yes — simply click a different case button, or retype/re-paste your original text. Conversions aren't saved anywhere, so refreshing the page also resets it.
