Frequently asked

Does the case converter upload my text?

No. Everything runs in your browser. Your text never leaves your device — you can even use this tool offline once the page has loaded.

Which cases are supported?

Twelve: lower case, UPPER CASE, Title Case, Sentence case, camelCase, PascalCase, snake_case, CONSTANT_CASE, kebab-case, dot.case, path/case, and aLtErNaTiNg case.

How does it detect word boundaries in camelCase or PascalCase input?

The converter splits on any non-alphanumeric character AND on transitions between lowercase and uppercase letters, so "helloWorld" or "HTMLParser" become "hello world" or "HTML Parser" before the target case is applied.

Can I share my conversion with someone?

Yes — the URL updates as you type. Copy the address bar and send it. When your recipient opens it, they see your exact input and selected case.
