About this tool
Casing is often the last-mile chore between a doc, a slug, and a variable name. This tool covers the ten shapes you actually reach for — no re-typing, no regex.
FAQ
- What's the difference between Title Case and Sentence case?
- Title Case capitalises every major word ("How To Ship Fast"). Sentence case only capitalises the first word and proper nouns ("How to ship fast").
- When should I use camelCase vs snake_case?
- camelCase is common in JavaScript and Java variable names. snake_case is standard in Python and SQL column names. kebab-case is used in URLs and CSS.
- Does it preserve line breaks and multiple paragraphs?
- Yes. Line breaks and paragraph structure are always preserved — only letter casing and word separators change.
- Does it work with accented characters?
- Yes. Diacritics and non-Latin scripts are handled through your browser's built-in Unicode case mapping.
- Is anything uploaded?
- No. Conversion happens locally in your browser.
