About the Case Converter
The Case Converter shows your text in ten cases at once — UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE and dot.case — each with its own copy button. It’s handy for headlines, variable names, file names and fixing text typed with Caps Lock on.

Frequently asked questions
Is the Case Converter free?
Yes. Case Converter is completely free with no sign-up, no usage limits and no watermarks.
Is my data private?
Yes. The Case Converter processes everything in your browser. Signed out, nothing is saved; signed in, your inputs sync privately to your own account.
What is the difference between Title Case and Sentence case?
Title Case capitalizes the first letter of each major word (“The Quick Brown Fox”). Sentence case capitalizes only the first word of each sentence and proper nouns (“The quick brown fox”).
What are camelCase, snake_case and kebab-case?
They are naming styles used in code: camelCase joins words and capitalizes each after the first (userName), snake_case joins with underscores (user_name) and kebab-case joins with hyphens (user-name).
Does it work on my phone?
Yes. Toolbench runs in any modern browser on desktop, tablet or phone — there is nothing to install.
