Case Converter
Easily convert text between UPPERCASE, lowercase, Title Case, camelCase, and more.
What is the Case Converter Tool?
The Case Converter is a versatile, free online utility that allows you to instantly change the capitalization of your text. Have you ever typed a long paragraph only to realize you accidentally left the Caps Lock key on? Instead of retyping everything from scratch, simply paste your text into our tool and convert it to lowercase or sentence case with a single click.
Supported Text Formats
We support a wide variety of text transformations tailored for both everyday writing and software development:
- Sentence case: Capitalizes only the first letter of each sentence. Perfect for fixing all-caps text.
- lowercase & UPPERCASE: Converts all characters to small letters or capital letters respectively.
- Title Case: Capitalizes the first letter of every word, which is ideal for blog post titles, book names, and headlines.
- Developer Cases (camelCase, snake_case, kebab-case): Instantly format your text into standard programming naming conventions. This is incredibly useful for developers naming variables, database columns, or CSS classes.
Fast, Free, and Privacy-Focused
Like all utilities on ToolDojo, the Case Converter operates entirely within your web browser using client-side JavaScript. Your text is never transmitted to our servers or stored in any database. This guarantees that your sensitive documents, private messages, and proprietary code remain completely secure on your own device.
