Change text case in one click

Accidentally typed a whole paragraph with caps lock on? Need a heading in Title Case, a variable in camelCase, or a URL slug in kebab-case? This case converter rewrites your text into any format instantly — no retyping, no formulas.

Every case you need

  • UPPERCASE / lowercase — fix caps-lock mistakes in a second.
  • Title Case / Sentence case — for headlines and clean body copy.
  • camelCase / PascalCase — for code identifiers.
  • snake_case / kebab-case / CONSTANT_CASE — for files, slugs and constants.
  • aLtErNaTiNg / InVeRsE — for memes and stylized social posts.

The conversion happens in your browser. Your text is never uploaded, so it’s safe for sensitive documents, client copy, or code you can’t share.

Frequently asked questions

What's the difference between Title Case and Sentence case?+

Title Case capitalizes the first letter of every word (great for headings). Sentence case capitalizes only the first word of each sentence (great for body copy).

What are camelCase, snake_case and kebab-case for?+

These are programming and slug formats. camelCase and PascalCase are common in code; snake_case and kebab-case are used for file names, URLs and CSS classes.

Will it keep my line breaks and punctuation?+

Uppercase, lowercase, Title and Sentence case preserve your spacing and punctuation. The code formats (snake, kebab, camel) intentionally strip separators to produce a clean slug.
