Will case conversion change punctuation?
No. It changes letter casing while preserving punctuation and spacing.
Case Converter
Convert text to uppercase, lowercase, title case, or sentence case.
Calculations happen locally. We do not send your values to our server.
Example
“hello WORLD” becomes “HELLO WORLD,” “hello world,” or “Hello World” depending on the selected mode.
Calculation method
Uppercase and lowercase use locale-aware browser casing. Title case capitalizes word starts; sentence case capitalizes text starts after sentence punctuation.
Important notes
Automatic title and sentence casing cannot reproduce every language or editorial style rule.
Frequently asked questions
Does title case follow a specific style guide?
No. It applies a simple capitalization rule rather than AP, Chicago, or another editorial standard.
Is the original text stored?
No. It remains only in the page unless you copy the result.
