About Base64Toolkit
Base64Toolkit is a free collection of Base64 tools built by engineers, for engineers. It was
born out of everyday DevOps frustration: decoding Kubernetes secrets one jsonpath at a time,
remembering whether base64 wants -d or -D on this
machine, and pasting production tokens into random websites without knowing where that data
goes.
What makes us different
- Instant, both ways, one screen. No encode/decode mode switch, no submit button. Type in either box and the conversion happens live.
- 100% client-side. Every tool on this site is a static page whose logic runs in your browser. Your input is never uploaded, logged, or stored on any server — the tools even work offline once the page is loaded.
- Built for real workflows. Decode a whole Kubernetes Secret manifest at once, copy results as ready-to-use
Authorizationheaders or data URIs, inspect JWT claims with expiry checks, and view raw bytes as hex. - Fast and clean. Static HTML, no heavy frameworks, dark mode, and full mobile support.
