Convert your text between eight common letter cases — from UPPERCASE to camelCase — with one click.
Paste your input into the editor.
Choose format / mode options if available.

Writers typically use Title Case for headings and Sentence case for body text. Developers use camelCase for JavaScript variables, PascalCase for classes and components, snake_case for Python and databases, and kebab-case for URLs and CSS classes.
Paste into Case Converter, tweak options, and copy the output. Formatting and conversion run in the browser for this tool.
Keep a backup of original input before bulk transforms. Invalid input should show an error instead of silent corruption.
Whenever possible, Case Converter processes your data locally with JavaScript in this page. That means drafts, secrets, and unfinished work stay on your device by default. Prefer this workflow when you do not want to upload sensitive text, tokens, passwords, or files to a third-party service.
camelCase starts with a lowercase letter (myVariableName), while PascalCase starts with an uppercase letter (MyClassName) — both remove spaces and capitalize subsequent words.
