About HandyTool
A clean, private, and fast toolbox for developers.
Our mission
In daily work we often need small-but-important utilities: format JSON, Base64 encode/decode, preview Markdown. HandyTool focuses on a distraction-free experience.
We keep privacy first. Everything runs locally in your browser.
Free forever
No paywalls. No limits for the core tools.
Developer-first
Minimal UI, dark-first, designed for developer taste.
