Convert text to UPPERCASE, lowercase, Title Case, camelCase, snake_case, and more — instantly, right in your browser.
This tool covers both everyday writing formats — UPPERCASE, lowercase, Title Case, and Sentence case — and programming-specific formats used for naming variables, functions, and files: camelCase, PascalCase, snake_case, kebab-case, and CONSTANT_CASE.
For the programming formats, the tool intelligently splits your input on spaces, hyphens, underscores, and camelCase boundaries — so you can convert cleanly between any of these styles, not just from plain text.
Both join words with no spaces and capitalize the start of each word. camelCase starts with a lowercase letter (userProfile), while PascalCase starts with an uppercase letter (UserProfile). By convention, camelCase is used for variables and functions, and PascalCase for classes and components.
Most programming languages don't allow spaces inside an identifier — a space ends the token. snake_case and kebab-case (and camelCase/PascalCase) are different ways to join multiple words into a single valid identifier or URL slug.
No. This is a format converter, not a grammar checker. It changes the capitalization of letters based on rules — it doesn't add periods, fix spelling mistakes, or identify proper nouns.
Title Case capitalizes the first letter of every word, commonly used for headings. Sentence case capitalizes only the first letter of each sentence, like normal prose — this is the default style for most writing.
No. All conversion happens directly in your browser — your text is never uploaded to a server or stored anywhere.
