Case conversion notes
Local conversionYour text is transformed in the browser and is never uploaded.
Language-aware title caseCommon short words stay lowercase in supported languages unless they begin or end the title.

Unicode and locale supportAccented letters, non-Latin scripts, emoji graphemes and locale-specific letter casing are preserved where the browser supports them.
Case converter FAQ
What is the difference between camelCase and PascalCase?
camelCase begins with a lowercase word, while PascalCase capitalizes the first word too.
Can I create URL slugs and file names?
Yes. Use kebab-case for readable URL slugs or snake_case and kebab-case for file-friendly names.
Does it support accented and non-Latin text?
Yes. Conversion uses Unicode word detection, browser segmentation and locale-aware letter casing with a Unicode fallback.
Does this tool change my original text?
No. The input remains editable and the converted result appears separately in the output area.
