Everyone has typed a paragraph with caps lock on. Rather than retype it, change the case with one click.
Quick answer
Paste your text and choose UPPERCASE, lowercase, Title Case, Sentence case, camelCase, snake_case or kebab-case.
What each does
| Style | Example |
|---|---|
| UPPERCASE | HELLO WORLD |
| lowercase | hello world |
| Title Case | Hello World |
| Sentence case | Hello world. This is a test. |
| camelCase | helloWorld |
| snake_case | hello_world |
| kebab-case | hello-world |
Steps
- Paste the text.
- Choose the case style.
- Copy the result.
When to use which
- Title Case: headings and book titles.
- Sentence case: body text and many headlines.
- UPPERCASE: acronyms, warnings and labels (use sparingly; it is harder to read).
- camelCase / snake_case: variable names in code.
- kebab-case: URLs and file names.
Tips
- Title Case tools usually capitalise every word; style guides leave small words like "of" and "the" lower case, so review headings.
- Names with special capitalisation (McDonald, iPhone) may need a manual fix.
- Bangla has no upper and lower case, so these changes affect only Latin letters.
- Keep a copy of the original in case you need it.
