Case Converter

Fix caps-lock accidents and switch between eight text cases in one click.

When to use each case

  • UPPERCASE / lowercase — rescue text typed with caps lock on, or normalize input.
  • Title Case — headlines, titles, and headings.
  • Sentence case — turning shouty ALL-CAPS text back into readable prose.
  • camelCase / snake_case / kebab-case — variable names, database columns, and URL slugs for developers.
  • aLtErNaTiNg — the internet's sarcasm font.

Everything converts instantly in your browser — paste, click, copy. To count what you've written use the word counter, and for blank Unicode tricks see the invisible character tool.

Frequently Asked Questions

What case options does this converter support?

UPPERCASE, lowercase, Title Case, Sentence case, aLtErNaTiNg case, camelCase, snake_case and kebab-case — one click each. Your text is converted live in the browser and never uploaded.

What is the difference between Title Case and Sentence case?

Title Case Capitalizes The First Letter Of Every Word — used for headlines. Sentence case only capitalizes the first letter of each sentence, like normal prose.

What are camelCase, snake_case and kebab-case for?

They are naming styles used in programming. camelCase joins words with capitals (myVariableName), snake_case uses underscores (my_variable_name), and kebab-case uses hyphens (my-variable-name) — common in URLs and CSS.

Can I fix text that was typed with caps lock on?

Yes — paste it and click Sentence case or lowercase to rescue ALL-CAPS text instantly, instead of retyping it.
