Case converter

Convert text between upper, lower, title, sentence, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, and dot.case.

Features

Ten case styles in one tool, including programmer-friendly camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE and dot.case.
Live conversion with a character count, so you can reformat variable names, headings or slugs as you type.
Runs entirely in your browser — paste sensitive code or copy results without anything leaving your device.

How it works

Paste or type your text into the input box — nothing is uploaded and there is no file to drop.
Pick a case from the menu: UPPER, lower, Title, Sentence, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE or dot.case.
The converted text updates live; copy it or download it as a .txt file.

Your files never leave this page

Every conversion runs entirely in your browser using WebAssembly. There is no upload, no server-side processing, no analytics, and no cookies. Open DevTools → Network during the operation and you will see zero outbound traffic.
