Free Case Converter

camelCase joins words with no spaces, keeps the first word lowercase and starts each later word with a capital. Type background color here and the camelCase card shows backgroundColor. It's the usual style for variable and function names in JavaScript, Java and Swift.

Only the first letter differs. camelCase starts lowercase, as in backgroundColor, and PascalCase starts with a capital, as in BackgroundColor. PascalCase is common for class and component names, and this tool shows both cards side by side so you can copy either one.

Use snake_case, with underscores, for Python names, Ruby and SQL columns. Use kebab-case, with hyphens, for CSS classes, file names and URL slugs. The converter lowercases every word for both, so background color becomes background_color or background-color.

Title Case capitalizes the first letter of every word, as in The Quick Brown Fox. Sentence case capitalizes only the first word of each sentence, as in The quick brown fox, which matches normal prose. Headlines often use Title Case; app labels and body text use Sentence case.

Paste the text into the box and copy the lowercase card. For text typed in caps lock, the Sentence case card is often better, since it also capitalizes the start of each sentence. Then fix any names or acronyms by hand.

No. This Title Case capitalizes every word, including short ones like a, of and the, so you get The Lord Of The Rings. It also lowercases the rest of each word, turning NASA into Nasa. Adjust small words and acronyms by hand for AP or Chicago style.

Not directly. Existing camelCase isn't split at capital letters, so backgroundColor becomes backgroundcolor in snake_case. Add a space or underscore between the words first, as in background Color, and the snake_case card shows background_color. snake_case and kebab-case input do convert.

Digits stay in every case, so version 2.0 release becomes version_2_0_release. Symbols and punctuation are dropped from the four code cases. UPPERCASE and lowercase handle accents, but Title Case misses a word that starts with one (élan becomes éLan) and the code cases keep only a to z, so café crème becomes caf_cr_me.

The result cards show text as one flowing paragraph, so line breaks and extra spaces look merged on screen. The copied text from UPPERCASE, lowercase, Title Case and Sentence case keeps them. The four code cases always join everything into a single name.

Paste the title and copy the kebab-case card. My First Blog Post! becomes my-first-blog-post, with spaces turned into hyphens, letters lowercased and the punctuation removed. An accented letter splits a word, so café becomes caf. Check slugs with accents before you publish.

No. Conversion runs in your browser and the text isn't saved, so it's gone when you close the page. On the live site, Google Analytics counts edits and Copy clicks, never the text or which case you picked.
