How it works
Type or paste your text into the box, then click a case button — the text is rewritten instantly, with no page reload. Only the capitalization of letters changes; your spaces, line breaks, numbers, and punctuation stay exactly where you left them. Sentence case capitalizes the first letter after each period, question mark, or exclamation point; Title Case capitalizes the first letter of every word; alternating and inverse case are mostly for stylistic effect. Live counts for characters, words, sentences, and lines update as you go. Everything runs locally in your browser — your text is never uploaded or stored.

FAQ
What is the difference between Title Case and Sentence case?
Title Case capitalizes the first letter of every word, which is common for headlines and titles. Sentence case capitalizes only the first letter of each sentence and leaves the rest lowercase, like normal prose.
What does alternating case do?
Alternating case switches between lowercase and uppercase for each letter, producing text like aLtErNaTiNg. It is mostly used for stylistic or playful effect on social media.
Does the converter change my original spacing and punctuation?
No. Only the capitalization of letters changes. Spaces, line breaks, numbers, and punctuation stay exactly where you put them.
Is my text uploaded anywhere?
No. All conversions run entirely in your browser. The text you paste is never transmitted to a server or stored.
