About this tool

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.
