About FreeTool Hub
Welcome to FreeTool Hub — your one-stop destination for free online calculators, developer utilities, text tools, image tools, and converters. Whether you are tracking your health with our BMI calculator, planning your finances with our loan calculator, formatting JSON and XML for your next project, or converting text cases, we have a tool for you.
Our calculators cover health, finance, and everyday conversions. The BMI calculator helps you understand your body mass index, the loan calculator shows monthly payments and amortization schedules, the age calculator gives you your exact age, and the unit converter handles metric and imperial conversions.
For developers, our JSON/XML formatter provides formatting, validation, minification, conversion, and a tree grid view. Our text tools include word counters, case converters, and lorem ipsum generators. Image tools help you compress images, generate QR codes, and pick colors. Converter utilities handle Base64 encoding, URL encoding, CSV/JSON conversion, Markdown editing, hash generation, cron expression editing, and YAML formatting — all running locally in your browser for maximum privacy.
Our World Time tool lets you track time across the globe with live analog clocks, sunrise and sunset times, and beautiful day-night gradient cards that shift from dark to light based on whether the sun is up in each city.
