Frequently Asked Questions
What is camelCase vs snake_case?
camelCase combines words without spaces, capitalizing each word after the first (helloWorld). snake_case uses underscores between words (hello_world). Both are common in programming.
Is my text sent to a server?
No. All conversions happen entirely in your browser using client-side JavaScript. Your text never leaves your device.
Does Title Case capitalize small words?
Our Title Case capitalizes the first letter of each word. For APA/MLA style (lowercase for articles, conjunctions), you may need to adjust manually.
