Text Case Converter
This tool provides several transparent text-case transformations without changing the original text on a server.
Convert text to sentence, lower, upper, title, or kebab case
Paste a short text sample and choose a predictable case transformation.
Processing mode: browser-only for this tool. The interface does not require a server upload to perform its transformation.

This tool provides several transparent text-case transformations without changing the original text on a server.
Designed for: Editors, developers, and content teams preparing headings, labels, identifiers, and examples.
How to use this tool
Paste text, choose a target case, and convert. Review acronyms, proper names, punctuation, and language-specific capitalization before publishing the result.
How the result is produced
The browser splits text into simple word-like tokens and applies the selected transformation. Kebab case is intended for slug-like examples, not automatic changes to existing live URLs.
Test examples
“API response status” becomes “api-response-status” in kebab case and “Api Response Status” in a simple title case. Acronyms may need manual correction.
Limitations
Capitalization rules differ by language and editorial style. The tool does not preserve every acronym convention, smart title-case exception, or locale-specific grammar rule.
Privacy and processing
Text transformations are performed locally in the browser and are not uploaded.
