Case Converter
Transform pasted text between common capitalization styles without retyping it. Use uppercase or lowercase for normalization, title case for headings and sentence case for ordinary prose.
Conversion runs locally in your browser. Title and sentence case use general-purpose casing rules rather than a publication-specific style guide.
How this tool works
The selected transformation changes letter casing while preserving the underlying characters and spacing as much as possible. Title and sentence case use lightweight browser-side rules rather than a full linguistic grammar engine.
Example
“crunch ANYTHING fast” can become “CRUNCH ANYTHING FAST”, “crunch anything fast”, “Crunch Anything Fast” or “Crunch anything fast”.
Common questions
Does title case follow every publishing style guide?
No. It capitalizes words using a simple general rule and does not implement publication-specific exceptions for short conjunctions or prepositions.
Is my text uploaded anywhere?
No. The transformation runs in your browser in this implementation.
