About CodingSetu

CodingSetu is a free collection of 381+ online tools — calculators, converters, formatters, generators and cryptography utilities — for developers, students, finance folks and anyone who needs a quick, reliable answer without the friction.

What we believe

• Your data is yours. Every tool runs client-side in your browser. We don't have a server that receives what you type, so there's nothing for us to log, store or leak.
• No friction. No sign-up, no paywall, no “download our app” nag. Open a tool and use it.
• Fast, everywhere. The whole site is static and served from a global CDN, so pages load in milliseconds on any device or network.
• Honest and ad-light. No intrusive ads, no dark patterns, no selling your attention.

What's inside

• Calculators — EMI, SIP, GST, percentage and BMI.
• Converters — units (length, weight, temperature and more) and number bases (binary, octal, decimal, hex).
• Formatters — JSON formatter/validator and a text case converter.
• Generators — UUIDs and strong passwords.
• Cryptography — SHA hashes, Base64 and URL encoding.
