Convert casing for headlines, code comments, or data cleanup. Choose uppercase, lowercase, title case, or sentence case and apply it to any block of text. The converter runs entirely in your browser. There is no sign-up, no upload, and no server that sees your words. That makes it ideal for essays, social posts, translations, and anything confidential. Paste your draft, get instant results, and copy the output in one click. Because everything is client-side, it works offline after the page loads and stays fast on mobile networks in Kigali or anywhere else. Title case respects Unicode letters so names like "Müller" stay readable.
Free, instant, private — your text never leaves your device.
