FAQ

Frequently Asked Questions About Case Conversion

Everything you need to know about file privacy, technical limits, and in-browser processing.

What is Title Case?

Title Case capitalizes the first letter of major words while leaving minor words (like "and", "in", "the", "of") lowercase unless they begin the sentence.

What are camelCase, snake_case, and kebab-case used for?

These formats are widely used in software engineering: camelCase for variables (myVariableName), snake_case for Python/databases (my_variable_name), and kebab-case for URLs and CSS classes (my-variable-name).

Can I fix text that was accidentally typed with Caps Lock on?

Yes. Simply select "Sentence case" or "lowercase" to normalize the text instantly.

Is there a limit on text length for case conversion?

No. You can convert short phrases, code identifiers, or entire book chapters without restrictions.

Does this tool store what I paste?

No. All conversions happen entirely in your local browser memory.
