Why Use Textoolz?

Textoolz is a collection of 53 free online text tools built for developers, writers, content creators, and anyone who works with text daily. Need to convert text to uppercase, format a messy JSON response, encode a string to Base64, count words in an essay, or generate bold Unicode text for social media? Textoolz provides fast, reliable tools for all of these tasks and more — completely free, with no sign-up required.

Every tool runs entirely in your browser using JavaScript. Your text is never uploaded to a server, stored in a database, or shared with third parties. This client-side approach means processing is instant even for large documents, your sensitive data stays private, and the tools work offline once the page has loaded. There are no accounts to create, no ads to dismiss, and no limits on how much text you can process.

The toolkit spans six categories: text case converters for changing capitalization, Unicode text formatting generators for social media styling, text manipulation tools for sorting and cleaning data, text analysis utilities for counting words and comparing documents, code formatters for beautifying JSON, HTML, CSS, SQL, and more, plus encoding and decoding tools for Base64, URL encoding, hex, binary, and beyond. Each tool is designed to do one thing well, with real-time preview as you type and one-click copy to clipboard.
