Frequently asked questions
How do I change text to uppercase or lowercase?
Paste your text, then click UPPERCASE or lowercase (or any of the other cases). The converted text appears straight away, ready to copy. There's no limit and nothing is uploaded, so it works for everything from a single headline to a long document.
How does Title Case work?
Title Case capitalises the first letter of every word and lower-cases the rest. It’s a simple, predictable rule — it doesn’t skip short words like “of” and “the”, so review headlines if you follow a specific style guide.
What’s the difference between camelCase and PascalCase?
Both remove spaces and capitalise each word. camelCase keeps the very first word lower-case (myVariableName); PascalCase capitalises it too (MyClassName).
Can it convert programming identifiers?
Yes. The converter understands existing camelCase, snake_case, kebab-case and dot.case boundaries, so you can switch a variable name from one convention to another in one click.
What is a text case converter and how do I use it online?
A text case converter is a free online tool that instantly changes the capitalisation of your text. Paste your text, click a case like UPPERCASE, lowercase, Title Case or Sentence case, then copy or download the result — there's no limit and nothing is uploaded.
How do I convert text to snake_case, kebab-case or CONSTANT_CASE?
Paste your text and click snake_case, kebab-case, CONSTANT_CASE or dot.case in the case picker. The converter detects existing word and identifier boundaries, so it's ideal for turning variable names, URL slugs and config keys into the naming convention you need.
Is my text uploaded anywhere?
No. All conversion happens in your browser with JavaScript — nothing you type is sent to or stored on a server.
