About PublicTools

PublicTools is a collection of small, focused online utilities for developers and everyday text tasks. The site is designed to load quickly, work without an account and keep processing in your browser whenever practical.

How the tools work

Tools such as JSON formatting, hashing, Base64 conversion, JWT decoding and text cleanup run with JavaScript in your browser. This keeps the server simple and reduces the need to transmit your input.

Advertising

The site may display advertising to support hosting and ongoing development. Advertising does not change the output of the tools.
