Frequently asked questions
What's the difference between Title Case and Sentence case?
Title Case Capitalizes Every Word; Sentence case only capitalizes the first word of each sentence.
What are camelCase, snake_case and kebab-case for?
They're naming styles used in programming: camelCase joins words with capitals, snake_case with underscores, kebab-case with hyphens.
Does it handle other languages?
Yes - conversion uses Unicode-aware rules, so accented and non-Latin characters are handled correctly.
Every case style, one click each
UPPERCASE for headings you've decided to shout, lowercase to undo a caps-lock accident, Title Case for headlines, Sentence case for prose - plus the programmer set: camelCase, PascalCase, snake_case and kebab-case. Paste once and click between styles; the conversion is instant and handles accented characters and non-Latin scripts correctly, because it uses Unicode-aware rules rather than A-to-Z arithmetic.
The styles, and where each belongs
Title Case Capitalizes Principal Words and is the convention for English headlines and book titles. Sentence case capitalizes only the first word and proper nouns - increasingly the house style for web headings, including most major tech companies' interfaces. For code: camelCase dominates JavaScript and Java variables, PascalCase names classes and React components, snake_case rules Python and database columns, and kebab-case belongs to URLs, CSS classes and file names, where underscores and spaces cause trouble.
Converting identifiers between conventions - say a CSV of database column names into camelCase keys - is exactly the kind of tedium this tool erases; it splits on spaces, underscores, hyphens and existing capital boundaries when re-casing.
Fixing text that arrived broken
The classic rescue job: a paragraph typed with caps lock on. Straight lowercase fixes the letters but loses sentence starts; Sentence case restores those too, recapitalising after each full stop, question mark and exclamation point. Nothing you paste is stored or transmitted - the conversion happens entirely in your browser, and the copy button grabs the result without touching the rest of the page.
