Retyping a heading because caps lock was on is wasted time. Paste the text, pick a format and copy the result. Sentence case fixes a shouted paragraph, title case tidies a heading, and the developer formats turn a phrase into a variable name or a clean URL slug.

Which format goes where

  • Title case for headlines and article titles
  • Sentence case for body text, buttons and interface labels
  • camelCase for JavaScript variables
  • snake_case for Python variables and database columns
  • kebab-case for URL slugs and CSS class names

Search engines do not rank uppercase text higher. All caps mainly slows readers down, so keep it for short labels at most.

Frequently asked questions

Does this work for long documents?

Yes. Conversion happens in your browser, so a full article converts instantly and never leaves your device.

Why does title case capitalise small words?

It uses the simple rule of capitalising every word. Style guides that keep articles and prepositions lowercase need a manual pass afterwards.

Can I make a URL slug with it?

Yes, pick kebab-case. Spaces and punctuation become single hyphens.
