A case converter built for writers, developers and everyone in between
Switching text between cases sounds simple until you actually need it — retyping a heading in Title Case, turning a variable name into camelCase, or fixing text that got stuck in aLtErNaTiNg CaPs from a bad paste. This tool handles all of it in one place, free and without an account.
It supports the everyday cases people reach for most: UPPERCASE and lowercase for quick formatting, Title Case and Sentence case for headings and body copy, and the programming-friendly styles — camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE — for naming variables, files and constants consistently. Alternating case and inverse case are included too, handy for stylized text or quick fun edits.
Alongside conversion, the tool keeps a live count of characters, characters without spaces, words, sentences and lines, plus an estimated reading time — useful when you’re working against a character limit for a post, meta description or tweet.
Everything runs directly in your browser. The text you type or paste is never uploaded to a server or stored anywhere — it exists only on your screen until you close the tab. When you’re done, copy the result with one click or download it as a plain text file.
Common questions

Title Case capitalizes the first letter of most words, the style used in headings. Sentence case only capitalizes the first letter of each sentence, the way normal prose is written.
They’re common naming conventions in programming. camelCase and PascalCase are typical for variables and class names, while snake_case and kebab-case are common in file names, URLs and configuration keys.
