Our Mission
Guangmings Tools was created with a simple goal: to provide fast, reliable online tools that respect your privacy. Too many tool websites are bloated with ads, require unnecessary sign-ups, or quietly upload your data to servers. We believe everyday utilities like formatting JSON, generating passwords, or converting units should be instant, free, and completely private.
Every tool on this site runs entirely in your web browser. Your data is never sent to any server, stored in any database, or shared with any third party. When you paste code into our JSON formatter or generate a password, the processing happens locally on your device using JavaScript. You can verify this by using our tools with your internet connection turned off — they still work perfectly.
What We Offer
We currently provide a growing collection of tools organized into three categories. Our developer tools include a JSON formatter and validator, Base64 encoder/decoder, URL encoder/decoder, HTML entity converter, and a Lorem Ipsum generator. Our text tools offer word and character counting with reading time estimates, and a versatile case converter. Our utility tools include a visual color picker with format conversion, a cryptographically secure password generator, and a comprehensive unit converter covering length, weight, temperature, speed, area, volume, and digital storage.
We are continuously expanding our tool collection based on user feedback and real-world needs. If there is a tool you would like to see added, please do not hesitate to reach out.
Our Principles
Privacy first. No data collection, no tracking beyond basic anonymized analytics, no cookies that monitor your behavior. Your data stays on your device.
Performance matters. Our tools load fast and work instantly. We keep the code lean and avoid unnecessary dependencies. No frameworks where vanilla JavaScript will do.
Always free. We sustain this project through minimal, non-intrusive advertising. Every tool remains completely free to use without limits, sign-ups, or premium tiers.
Open and honest. We do not use dark patterns, fake urgency, or manipulative design. What you see is what you get.
