About ToolSpark
ToolSpark is a collection of free online tools designed to help you with everyday tasks. Whether you need to convert units, generate QR codes, pick colors, or format JSON - we have you covered.
Our Principles
🔒 Privacy First
Every tool runs entirely in your browser. Your data never leaves your device. We do not collect, store, or transmit any of your input data.
⚡ Speed
No server round-trips, no loading spinners. Tools work instantly because all processing happens locally on your machine.
🆓 Free Forever
No accounts, no subscriptions, no premium tiers. Every tool is and will always be completely free to use.
📱 Mobile Friendly
All tools are designed to work perfectly on any device - phone, tablet, or desktop.
How It Works
ToolSpark is a static website - meaning there is no backend server processing your data. All calculations, conversions, and generations happen right in your browser using JavaScript. This approach ensures maximum privacy and speed.
