About FreeTool

Our Mission

FreeTool was created with a simple mission: to provide developers, designers, and everyday users with free, fast, and privacy-focused online tools. We believe that essential utilities should be accessible to everyone without compromising on quality or privacy.

What We Offer

We provide a comprehensive collection of 20+ developer tools, including:

  • JSON Tools: Formatter, validator, minifier, and converters (JSON to YAML, XML, CSV)
  • Encoding & Encryption: Base64, URL encoding, MD5, SHA, HMAC, AES, bcrypt
  • Text Tools: Text diff, case converter, word counter, find & replace
  • Time & Date: Unix timestamp converter, timezone converter, cron parser
  • Developer Tools: Regex tester, HTTP client, cURL converter, UUID generator
  • Web/CSS Tools: Color picker, gradient generator, box shadow designer

Privacy First

Unlike many online tools that process your data on their servers, all our tools run 100% in your browser. This means your sensitive data — whether it's JSON configurations, passwords, or encrypted content — never leaves your device. We can't see it, we can't store it, and we can't access it. Your privacy is guaranteed by design.
