About ZeroTools

ZeroTools is a collection of essential web utilities built entirely around one core philosophy: your data is yours.

The internet is full of "free" tools that secretly upload your files, track your usage, and sell your data. We decided to build an alternative. Every tool on this platform runs 100% locally in your browser using modern web technologies like WebAssembly and client-side APIs.

Zero Uploads

We don't even have a database. Your data never leaves your device.

Instant

No server round-trips means instant results.

Free Forever

No subscriptions, no paywalls, no annoying ads.

Our Mission

We believe that basic utilities shouldn't require you to trade your privacy. Whether you're generating a secure password, formatting a massive JSON payload, or manipulating an image, you should be able to do it quickly, for free, without worrying about who is watching.

Open Source

Trust, but verify. The entire codebase for ZeroTools is open source. We welcome contributions, bug reports, and feature requests from the community.
