🔡 Case Converter

Convert text to any case — click to apply, copy instantly.

The Case Converter transforms your text between UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case and kebab-case. Instant conversion with one click.

How to convert text case

Paste or type your text into the input box. As you type, every supported case appears in its own card below — click any card to copy that version to your clipboard. There's no "submit" button; conversion is live. The original text stays in the input untouched, so you can flip back and forth between formats. Mixed case, accidental caps lock, and copy-pasted email subject lines all clean up in a single click. Output is plain text, ready to paste into Word, Slack, GitHub, or anywhere else.

Why so many cases exist

Different communities settled on different conventions for joining words without spaces. JavaScript and Java picked camelCase for variables. Python picked snake_case. C# and Pascal picked PascalCase for class names. URL slugs and CSS classes use kebab-case. Title Case is the editorial standard for headlines. Sentence case is the natural English form for body copy. Knowing which case to use per context saves hours of manual reformatting; the tool covers every common variant in one place.

Frequently Asked Questions

What is Title Case?
Every major word is capitalised. Minor words (a, an, the, and, but, or) are usually lowercase unless they're the first word.
What is camelCase?
Words joined without spaces, each new word starting with a capital — like thisIsAnExample. Used in programming variable names.
What is snake_case?
Words joined by underscores, all lowercase — like this_is_an_example. Common in Python and database column names.
What is kebab-case?
Words joined by hyphens, all lowercase — like this-is-an-example. Common in URLs and CSS class names.
Will it preserve special characters?
Punctuation is preserved in the case modes (UPPERCASE, lowercase, Title Case, Sentence case). It's stripped in the programming-style modes (camelCase, snake_case, kebab-case) because those formats don't allow it.
Is the text saved anywhere?
No. The conversion happens entirely in your browser — refresh the page and the input is gone. Safe for confidential drafts.
