About EXUtil - Free Local Browser Tools
Learn about EXUtil, a free collection of browser-based developer and media tools designed for fast, private, local processing.
What is EXUtil?
EXUtil provides practical tools for JSON, encoding, encryption, image processing, file conversion, and diagrams in one focused workspace.
The site is built for developers, designers, analysts, and students who need a quick utility without installing another application.
Local-first processing
Supported tools process input in your browser. Files and text are not uploaded to an EXUtil application server for the normal tool workflow.
You should still review the privacy characteristics of any browser extension, network proxy, or third-party service used alongside EXUtil.
Keeping the tools useful
We maintain the tool descriptions, examples, and compatibility notes as browser APIs and industry standards evolve.
