About the Case Converter
Retyping text just to change its capitalisation is a waste of time — and error-prone. A case converter instantly transforms any text between UPPERCASE, lowercase, Title Case, Sentence case and developer formats like camelCase, snake_case and kebab-case, without you touching a single letter.
Paste your text, pick a case, and copy the result. The conversion happens live in your browser, so nothing you paste is stored or uploaded.

Tips & good to know
- Title Case keeps small words like 'and' or 'of' lowercase in many style guides — check yours.
- camelCase and snake_case are ideal for variable and function names.
- Sentence case only capitalises the first letter, which is handy for body text.
