What case formats does this converter support?

Seven formats: UPPER CASE, lower case, Title Case, camelCase, PascalCase, snake_case, and kebab-case. Switch between them in one click and the converted text appears instantly.

Is my text sent to a server?

All case conversion runs in your browser as pure JavaScript. Our servers are not involved at any point.

Does it handle accented characters?

Yes. The converter works with Unicode text including accented characters, so letters like e-acute and n-tilde are handled correctly.

Can I convert multiple paragraphs at once?

Yes. Paste any amount of text and the conversion applies to the entire input at once. UPPER CASE, lower case and Title Case keep your line breaks and punctuation.

Technical specification

Algorithm or formula: For camelCase, PascalCase, snake_case and kebab-case: tokenisation into words at spaces, punctuation and camelCase boundaries, then case-specific joiners (camelCase capitalises every word after the first, snake_case lowercases and joins with underscores, kebab-case with hyphens). UPPER CASE, lower case and Title Case change letters in place. Title Case capitalises each word except short articles, conjunctions and prepositions in the middle of a line, and keeps acronyms and mixed-case words such as iPhone.
Browser API or library: Native String.prototype methods (toLowerCase, toUpperCase, split, replace) with Unicode-aware regex. No external library.
Input limits: Bounded by available browser memory. Multi-megabyte text strings convert without issue on modern devices.
Output: Plain text in the chosen case format, copyable to the clipboard.
Known limitations: camelCase, PascalCase, snake_case and kebab-case output drops punctuation and lowercases acronyms (XMLHttpRequest becomes xmlHttpRequest).
