StraightToolsCase Converter
Change text capitalization instantly.
Private by default
The transformation happens locally in your browser; the tool does not need to send your text to a server.
When to use this tool
Use the case converter to quickly change text to uppercase, lowercase, title case, or sentence-style capitalization. It is useful when cleaning copied text or preparing headings and labels.
How the result is calculated
The conversion is performed in your browser by applying capitalization rules to the text you provide. Your original wording remains the same apart from letter case.
Worked example
“simple tools. straight answers.” can become “SIMPLE TOOLS. STRAIGHT ANSWERS.” or a title-style version in one click.
What to keep in mind
Automated title case does not understand every style guide, proper noun, acronym, or language-specific capitalization rule. Review important copy after conversion.
