Runs entirely in your browser. Nothing you type is uploaded. Title Case Converted text appears here… ## Every case, one click This **case converter** handles the everyday ones (UPPERCASE, lowercase, Title Case, Sentence case) and the developer ones: camelCase, PascalCase, snake\_case, kebab-case and CONSTANT\_CASE. Paste your text, pick a style, copy the result. It all happens in your browser. ## Stop re-finding the same snippets If you’re reformatting text you copied from somewhere, you’ll want it again later. **Relic** keeps a searchable, **end-to-end encrypted** history of everything you copy, on every device, so the variable names, headings and strings you work with are always a search away, forever. ## Frequently asked questions How do I change the case of my text?+ Paste your text into the box, then click the style you want and the converted result appears instantly below, ready to copy. You can switch between styles freely without retyping, since the tool always works from your original input. What case styles does this converter support?+ There are ten: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake\_case, kebab-case, CONSTANT\_CASE, and aLtErNaTiNg. That covers the everyday writing cases and the naming conventions developers use for variables and file names. How does Title Case handle small words like "of" and "the"?+ This tool capitalizes the first letter of every word, so "the lord of the rings" becomes "The Lord Of The Rings". It does not apply the editorial rule that leaves short words like of, the, and and lowercase, so if you need strict headline style you may want to lowercase those by hand afterward. What is the difference between camelCase, snake\_case, and kebab-case?+ All three join your words into one identifier with no spaces, which is why they show up so often in code. camelCase runs the words together with each new word capitalized (myVariableName), snake\_case joins them with underscores (my\_variable\_name), and kebab-case joins them with hyphens (my-variable-name). The converter builds these by pulling out the letters and numbers and dropping the punctuation. Does my text get uploaded when I convert it?+ No. The conversion runs entirely in your browser, so whatever you paste stays on your device and nothing is sent anywhere. That makes it safe for internal strings, unreleased copy, or anything you would rather not send to a server. You just copied that. What if you never lost it? **Relic** remembers everything you copy, forever, searchable on every device, and end-to-end encrypted so only you can read it. 250 MB free [Download forWindows](https://relic.space/download/windows)[Download formacOS](https://relic.space/download/macos)[Download forLinux](https://relic.space/download/linux)[Download forAndroid](https://play.google.com/store/apps/details?id=relic.space.app&referrer=utm%5Fsource%3Drelic.space%26utm%5Fmedium%3Dwebsite%26utm%5Fcampaign%3Dcontent)[Download foriPhone](https://apps.apple.com/us/app/relic-clipboard-vault/id6800556025) More free tools [Word Counterword counter](https://relic.space/tools/word-counter)[Lorem Ipsum Generatorlorem ipsum generator](https://relic.space/tools/lorem-ipsum-generator)[Markdown Editormarkdown editor](https://relic.space/tools/markdown-editor)[Syllable Countersyllable counter](https://relic.space/tools/syllable-counter)[Random Sentence Generatorrandom sentence generator](https://relic.space/tools/random-sentence-generator)[Readability Checkerreadability checker](https://relic.space/tools/readability-checker)[All tools](https://relic.space/tools)
