Frequently Asked Questions (FAQ)

What is Title Case?

Title Case capitalizes the first letter of every major word in a string. It is predominantly used for book titles, blog post headings, and essay headers to make them look more professional.

When should I use camelCase?

camelCase is primarily used in programming languages like JavaScript and Java to name variables and functions. The first word is lowercase, and each subsequent word starts with a capital letter (e.g., myVariableName).

What is the difference between snake_case and kebab-case?

Both replace spaces with punctuation. Snake case uses underscores (hello_world) and is popular in Python. Kebab case uses hyphens (hello-world) and is widely used for URLs and CSS class names.

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

Because the tool operates entirely locally in your browser, the limit is based on your device's memory. You can easily process tens of thousands of words instantly without lag.

Can I fix Caps Lock errors with this?

Yes! If you accidentally typed a paragraph with Caps Lock on, simply paste the UPPERCASE text here and select "Sentence case" or "lowercase" to fix it immediately.

What does Toggle Case do?

Toggle Case looks at your text and inverts the capitalization of every single letter. An uppercase "A" becomes "a", and a lowercase "b" becomes "B". It's a quick way to reverse Shift-key mistakes.
