Text Case Converter
This text case converter switches text between the case styles developers and writers use every day — upper, lower, title, sentence, camelCase, PascalCase, snake_case, kebab-case, and CONSTANT_CASE. Paste any text and every variant updates instantly, so you can copy the exact format your code or content needs. Conversion happens entirely in your browser, with no upload or signup required.
Frequently asked questions
What’s the difference between camelCase and PascalCase?
Both styles remove spaces and capitalize each word boundary; camelCase keeps the first letter lowercase (myVariableName) while PascalCase capitalizes it (MyVariableName).
How do I convert text to snake_case or kebab-case?
Paste your text into the input box and every case style — including snake_case and kebab-case — is generated at once in separate output fields, ready to copy.
Does the converter generate every case style at once, or do I pick one first?
Every style is generated at the same time — paste your text once and upper, lower, title, sentence, camelCase, PascalCase, snake_case, kebab-case, and CONSTANT_CASE all update instantly, so you can copy whichever version you need.
Is there a limit to how much text I can convert?
No fixed limit — conversion runs in your browser as you type, so the practical limit is your device’s performance rather than a server-imposed cap.
Does this tool store or upload the text I convert?
No. All case conversion runs locally in your browser — nothing is uploaded, logged, or saved.
