About ToolSMA

ToolSMA is a free collection of 42 online tools for everyday tasks — from mortgage and BMI calculators to QR codes, password generators and JSON formatting.

Our principles

• Free forever. Every tool is free to use with no accounts, trials or limits.
• Private by design. Calculations run in your browser. Text, images and files you use are never uploaded.
• Fast. Pages are pre-rendered and lightweight, so tools are ready in an instant on any device.
• Transparent. Each tool explains the formula or method it uses so you can trust the result.

Accuracy

We use standard, well-documented formulas and exact conversion factors. Results are for general information only and are not financial, medical or legal advice. For important decisions, please consult a qualified professional.
