Free text tools that keep your text private

Text often contains things that should not travel: a contract draft, an email to a client, an API response with customer data. Many online text tools still send whatever you paste to their server. These four tools do all their work in your browser, so the text you paste never leaves your device and nothing is saved.

The word counter gives exact numbers of words, characters with and without spaces, sentences and paragraphs, plus reading time, and it follows the rules of each language, so Turkish, Chinese, Japanese and Arabic are counted properly. The case converter switches between uppercase, lowercase, title case and programming styles such as camelCase and snake_case, with correct Turkish dotted and dotless i. Text Compare highlights every added and removed line, word or character between two versions. The JSON formatter validates JSON, points to the exact line of an error and formats or minifies it without changing any value.

Each tool is free, works on phones and computers, and needs no account. Results can be copied with one click.
