This change text case tool is built for speed and clarity. With one click you can convert to uppercase, lowercase, title case, sentence case, camelCase, PascalCase, snake_case, kebab-case, SCREAMING_SNAKE_CASE, alternating, or inverse case. Everything is inline above the result, so you never hunt for settings. Nothing is stored—everything runs in the browser with live preview and copy/download controls.
Paste text, tap a case button, and the transformation updates instantly. You can switch cases to preview different outputs and copy the one you need. Stats update automatically (words, characters, lines, reading time), and history lets you restore a recent transform in one click. The tool preserves emojis, numbers, and punctuation while adjusting only the casing.
Use sentence case for UX copy, title case for headlines, PascalCase for classes, camelCase for variables, snake_case for config keys, and kebab-case for URLs. SCREAMING_SNAKE_CASE is ideal for constants. Avoid ALL CAPS in long sentences to keep readability high. Keep your casing consistent across headings to improve scanability and SEO.
Full case suite, live preview, copy/download, quick stats, and history. Controls sit above the result for a frictionless flow. Whether you’re formatting blog posts, code variables, product descriptions, or social captions, everything you need is one click away.
Use sentence case for body copy, title case for headings, and kebab-case for clean URLs. Keep metadata concise, avoid ALL CAPS in long text, and maintain consistent casing across sections. This tool helps you enforce those rules quickly so your content is ready for search and sharing.
