About Tools

What is this site?

Tools collects small utilities for everyday work: a JSON formatter, Base64 encoder, QR code generator, Chinese converter, unit converters and more.

86 tools are available today, with more on the way.

Every tool runs as JavaScript in your browser. The text, files and images you use never reach our servers or anyone else’s.

The few tools that need the network say exactly what they send.

Yes. No sign-up, no sign-in and no ad tracking.
