The small jobs, sorted
Building software means a steady stream of small side tasks. Encoding a value to Base64, decoding a token to see what is inside, or checking the shape of some data. These tools handle each of those on their own, so you can grab the one you need and get back to the actual work. There is nothing to install and no account to create.
Private by design
Every tool here runs locally in your browser. When you type or paste, the work happens on your own device and nothing is sent to a server. That keeps the tools fast, since there is no round trip to wait on, and it means your data stays with you. Once a page has loaded, most keep working even if you go offline.
