About WebTool

WebTool (webtool.site) is a free online toolbox for developers, offering 60+ everyday tools: JSON formatting, encoding/decoding, crypto & hashing, code formatters, text processing, time conversion, network utilities and image tools.

Our Principles

• Privacy first: all computation runs locally in your browser. Your data never leaves your device — safe for sensitive payloads.
• Instant: no sign-up, no downloads, no pop-up ads. The tool is the homepage.
• Speed as a feature: statically pre-rendered pages with lazy loading — fast first paint, instant results.
• Readable errors: error messages tell you exactly which line and why, in plain language.
