About Developer Utilities

Developer Utilities collects the everyday tools developers reach for most often: Base64/URL encoding and decoding, JSON formatting and validation, UUID and random number generation, Unix timestamp conversion, and hash generation.

Runs entirely in your browser

Every tool in this category processes your input locally in your browser — nothing is uploaded to a server or stored. This makes them safe to use with sensitive strings, tokens, or data you don't want leaving your machine.

More general-purpose tools

A few related utilities used by developers and non-developers alike — QR code generation, password generation, color conversion, and more — live under the broader Online Tools category.
