About Fieldkit

Fieldkit is a small, growing set of developer utilities: formatters, converters, and generators for the tasks that come up constantly and deserve a tool that doesn't get in the way.

Design principles

• No signup. Every tool is usable the moment the page loads.
• Runs in your browser. Nothing you paste is uploaded to a server.
• One page, one job. Each tool does exactly one thing well.

How this site is funded

Fieldkit is free to use and supported by display advertising. No tool's functionality is limited or gated behind ads.
