Tech & Developer Tools

Tech and developer tools handle quick conversions and checks that come up in IT and web work. The IP subnet calculator turns an IPv4 address and CIDR prefix into a network address, broadcast address and usable host count. The bandwidth calculator estimates how long a file transfer takes at a given speed.

For encoding, the Base64 encoder and decoder converts text to and from Base64, and the URL encoder applies percent encoding for query strings. The binary and hex converter calculators switch numbers between bases, and the password generator creates random passwords of the length you choose.

The tools run in your browser. Even so, avoid pasting live secrets or production credentials into any online tool. For number-base work across more units, see the number base converter, and for file formats see the separate file tools library.
