Text Case Converter
Convert text case and naming style in one click: UPPERCASE, lowercase, Capitalized, Title Case, Sentence case, camelCase, PascalCase and more. All 10 formats update live and each can be copied individually — entirely in your browser.
How to use
- Paste or type the text to convert in the box above — all 10 formats refresh instantly as you type.
- Each format has its own row: the left side shows the format name and its result, and the "Copy" button on the right copies that format alone.
- Upper, lower, capitalized and similar formats work on any letter text; word-based formats such as camelCase or snake_case split words on letters and digits before joining.
- Use "Example" to load demo text and explore the differences between formats; "Clear" resets the input and results.
- All conversion happens locally in your browser — nothing is uploaded, so it is safe for code identifiers or whole articles.
FAQ
What is the difference between Capitalized and Title Case?
Capitalized only uppercases the first letter of each word and leaves the rest untouched; Title Case uppercases the first letter of each word and lowercases the remaining letters, matching a more traditional headline style.
How do naming formats like camelCase handle Chinese text?
These formats split text into words made of consecutive English letters and digits before joining with the chosen separator. Pure Chinese is not split, so text containing CJK characters is preserved (translating or processing line by line is recommended first).
What are the sentence boundaries for Sentence case?
The text is lowercased first, then the first letter of every sentence is uppercased. Sentences are detected using periods ., exclamation marks !, question marks ? and newlines.
Is my text uploaded to a server?
No. All conversions run locally in your browser, so the text you enter never leaves your device.
