Text Case Converter
Convert text between UPPERCASE, lowercase, Title Case, Sentence case, and more. Quickly format your text the way you need it.
What Is a Text Case Converter?
A text case converter changes the letter casing of your text without altering the words themselves. Instead of retyping a heading in all caps or manually fixing capitalization in a pasted paragraph, you can convert it instantly — punctuation, spacing, and word order all stay exactly as you wrote them.
This is especially useful when copy needs to match a specific style: headlines in Title Case, body text in Sentence case, or variable names in camelCase for code.
Case Styles Explained
Each case style follows a different capitalization rule. Here's what each one does:
| Case | Example | Typically used for |
|---|---|---|
| UPPERCASE | HELLO WORLD | Headlines, warnings, acronyms |
| lowercase | hello world | Usernames, tags, casual styling |
| Title Case | Hello World | Blog titles, book and film titles |
| Sentence case | Hello world | Standard prose and paragraphs |
| Capitalize Each Word | Hello World | Headings, menu items |
| camelCase | helloWorld | JavaScript variable names |
| PascalCase | HelloWorld | Class names, component names |
| snake_case | hello_world | Python variables, database fields |
| kebab-case | hello-world | URLs, CSS classes, file names |

Frequently Asked Questions
What is a text case converter?
A text case converter is a tool that automatically reformats text into a different letter casing, such as uppercase, lowercase, title case, or sentence case, without you having to retype anything.
Does converting case change punctuation or spacing?
No. Only the letter casing changes. Punctuation, numbers, and spacing stay exactly as you typed them.
What is the difference between Title Case and Sentence case?
Title Case capitalizes the first letter of most words, commonly used for headlines and titles. Sentence case capitalizes only the first letter of each sentence, matching how normal prose is written.
What are camelCase and snake_case used for?
camelCase and snake_case are naming conventions used in programming. camelCase joins words with no spaces and capitalizes each word after the first, while snake_case joins words using underscores in place of spaces.
Is this tool free and does it store my text?
Yes, the tool is completely free with no sign-up required. All conversion happens locally in your browser, so your text is never uploaded or stored.
