Case Converter

Fix the case of a headline, a stubborn all-caps paragraph, or a variable name in one click — then copy the result.

How it works

Paste your text and pick a case. Each button transforms the whole block: UPPERCASE and lowercase are self-explanatory, Title Case capitalizes every word, and Sentence case capitalizes only the first letter of each sentence.

The programmer cases are there too. camelCase joins words with no spaces and capitals from the second word on, snake_case links them with underscores, and kebab-case uses hyphens — handy for variable names, file names, and slugs.

Conversions stack, so you can go from a messy paste to Title Case to camelCase in two taps. Hit Copy when it looks right, and it all stays in your browser.

Frequently asked questions

What is the difference between Title Case and Sentence case?

Title Case capitalizes the first letter of every word, like a headline. Sentence case capitalizes only the first word of each sentence, like normal prose.

What is camelCase used for?

Mostly programming. camelCase writes multi-word names with no spaces and a capital on each word after the first — like firstName or totalCost — which many languages use for variables.

Can I undo a conversion?

Conversions apply to whatever is currently in the box, so if you overshoot you can just apply another case or re-paste your original text. Nothing is saved between visits.
