About ConvertJSON.io

ConvertJSON.io is a collection of free, developer-focused tools for converting between common data formats. Whether you need to convert YAML to JSON, encode Base64, or decode URL parameters, we have you covered.

Our Mission

We built ConvertJSON.io because we were tired of hunting for reliable, ad-free conversion tools. Our goal is simple: provide fast, free, and privacy-respecting tools that just work.

Privacy First

All conversions happen entirely in your browser using JavaScript. Your data never leaves your device and is never sent to our servers. This means you can safely convert sensitive configuration files, credentials, and other private data.

Built for Developers

We designed these tools with developers in mind. That means:

  • Dark mode by default (because who codes in light mode?)
  • Keyboard shortcuts for power users
  • Clean, distraction-free interface
  • Monospace fonts for code readability
  • No sign-up required
  • No usage limits

Open and Transparent

We believe in transparency. There are no hidden trackers, no data collection, and no monetization schemes. We sustain this project simply because we use these tools ourselves.

Questions or Feedback?

If you have suggestions for new tools, find a bug, or just want to say hi, we would love to hear from you. These tools are built for the developer community, and your feedback helps us improve.
