About these case formats

  • UPPERCASE, every letter capitalized, often used for emphasis or acronyms.
  • lowercase, every letter in lowercase, useful for normalizing input like usernames or emails.
  • Title Case, the first letter of each major word capitalized, common in headings and titles.
  • Sentence case, only the first letter of each sentence capitalized, matching normal prose.
  • camelCase, words joined with no spaces, each word after the first capitalized, used in programming variable names.
  • snake_case, words joined with underscores, all lowercase, also common in programming and database fields.

Frequently asked questions

Will punctuation and numbers be affected?+
Punctuation is preserved. Numbers are untouched since case doesn't apply to digits. camelCase and snake_case strip most punctuation since those formats are meant for identifiers.
Does this tool save what I type?+
No. The conversion happens entirely in your browser. Nothing is sent to a server or stored.
