About Textoolz

Textoolz is a collection of 53 free online text tools built for developers, writers, and anyone who works with text. Every tool runs entirely in your browser — your text is never sent to any server.

Why Textoolz exists

Text transformation is something developers and writers do every day: converting case, formatting code, encoding data, cleaning up lists. Most online tools for these tasks are cluttered with ads, require sign-ups, or send your data to remote servers. Textoolz was built as a fast, clean, privacy-respecting alternative.

Privacy by design

All text processing happens client-side using JavaScript in your browser. No text data is transmitted to any server, stored in any database, or shared with any third party. For large inputs (over 100KB), processing is offloaded to a Web Worker to keep the interface responsive — still entirely in your browser.

What's included

53 tools across 6 categories:

• Text Case Converters — uppercase, lowercase, title case, camelCase, snake_case, and more
• Text Formatting — bold, italic, strikethrough, and other Unicode text styles
• Text Manipulation — sort, deduplicate, find and replace, trim, and more
• Text Analysis — word count, character count, reading time, text diff
• Code Formatters — JSON, HTML, CSS, JavaScript, SQL, XML, YAML
• Encoding & Decoding — Base64, URL, hex, binary, ROT13, Morse code, MD5

Technology

Textoolz is built with Next.js, React, and TypeScript. Code formatting tools use Prettier and dedicated parsers. The site is statically generated for fast load times and deployed as a containerized application.
