Frequently asked questions
Which case styles does this tool produce?
Seven at once: UPPERCASE, lowercase, Title Case (each word capitalized), Sentence case (first letter of each sentence capitalized), camelCase, snake_case and kebab-case. You never need to convert twice.
How are camelCase, snake_case and kebab-case derived?
Your text is split into lowercase words on spaces, hyphens, underscores and existing camelCase boundaries. The words are then joined without separators with each word capitalized (camelCase), with underscores (snake_case) or with hyphens (kebab-case).
What is the difference between Title Case and Sentence case?
Title Case capitalizes the first letter of every word, which suits headings and titles. Sentence case lowercases everything and then capitalizes the first letter of each sentence, which suits body text and subtitles.
Is my text uploaded anywhere?
No. The conversion happens locally in your browser as you type. Your text never leaves your device — nothing is stored, logged or uploaded.

About this tool
This free case converter turns one piece of text into seven letter-case styles at once — UPPERCASE, lowercase, Title Case, Sentence case, camelCase, snake_case and kebab-case — so you never convert twice. Type or paste into the editor and every style appears immediately, ready to copy the variant you need. It covers the two audiences that fight over the shift key every day: writers fixing a paragraph that was typed with Caps Lock on, and developers normalizing identifiers between conventions — a "user email address" column becomes userEmail in camelCase for JavaScript, user_email in snake_case for Python or SQL, and user-email in kebab-case for CSS classes, URLs and CLI flags. The conversion runs as you type, entirely in your browser; nothing is uploaded, nothing is stored, and there is no limit on how often you use it. Paste a headline, a code identifier or a whole paragraph and pick whichever style fits — all seven are always on screen.
