Frequently Asked Questions

Quick answers about controls, features, accuracy, and local browser saving.

What is the difference between Title Case and Sentence case?

Title Case capitalizes the first letter of major words while leaving short prepositions and conjunctions (and, but, in, on, the) lowercase. Sentence case capitalizes only the first letter of each complete sentence.

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

These casing conventions are widely used in software engineering: camelCase for JavaScript variables and functions, PascalCase for React/Vue components and class names, kebab-case for URL slugs and CSS classes, and snake_case for Python variables and database columns.

Is there a limit on how much text I can convert?

No. The converter processes thousands of words instantly in your browser's memory with zero server lag.

Is my text private?

Yes, 100%. All case transformations run strictly on the client side. No text is ever uploaded or saved on any remote server.
