Frequently asked questions
What does a case converter do?
A case converter changes the capitalization of your text. Paste any text, pick a style like UPPERCASE or Title Case, and it rewrites every letter to match — much faster than retyping or fixing capitals by hand.
What is the difference between Title Case and Capitalize Each Word?
Title Case follows headline style: it capitalizes major words but keeps minor words like “and”, “the”, “of”, and “to” lowercase (unless they start or end the title). Capitalize Each Word capitalizes every single word with no exceptions.
Which case should I use for a blog headline?
Title Case is the standard for blog headlines and article titles in the US. Use Sentence case for academic or journal-style headings, and UPPERCASE sparingly — for short labels or emphasis only, since full uppercase reads as shouting.
What are camelCase, snake_case, and CONSTANT_CASE used for?
They are naming conventions in programming. camelCase (myVariable) is common in JavaScript, snake_case (my_variable) in Python, and CONSTANT_CASE (MY_CONSTANT) for fixed values. Developers also use kebab-case (my-variable) in URLs and CSS classes.
Can I convert a long document?
Yes. There is no length limit — paste an entire essay, article, or report and convert it in one click. Everything runs locally in your browser, so even long texts convert instantly.
Is my text uploaded or saved anywhere?
No. Conversion happens entirely in your browser. Your text never leaves your device, is never sent to a server, and is never stored.
Does it work on my phone?
Yes. The converter is mobile-friendly and works in any modern browser on iPhone and Android.
