Built for Privacy
ZeroUpload is a free, privacy-first toolkit for developers, designers, and anyone who believes their data should stay theirs.
👋 Who We Are
ZeroUpload was built by developers and privacy advocates who were tired of the status quo — tools that ask you to "just upload your file," then quietly store, analyze, or monetize it.
We're a small team that believes powerful tools don't require sacrificing privacy. Every tool runs entirely in your browser — no backend, no storage, no data collection. We stay lean deliberately, because our mission is tools, not data.
🎯 Our Mission
To make professional-grade browser tools freely available to everyone — with zero compromise on privacy. We want to prove that "free" and "private" can coexist without one cancelling the other.
"Your data should be yours. The moment you upload it to a tool you don't control, you've handed away a piece of your privacy — and often you can't get it back."
⚡ Our Values
Privacy First, Always
We don't collect what we don't need. Every architectural decision starts with "what's the least we can know?"
Genuinely Free
No freemium traps, no feature walls, no premium tiers. All 8 tools are free forever with no strings attached.
Radical Transparency
You can verify in browser DevTools that no data is being sent anywhere. We welcome that scrutiny.
Speed Through Simplicity
Local processing means instant results. No server round-trips, no latency, no downtime affecting you.
Respect for Users
We don't track behavior, build profiles, or sell data. We don't even know who you are — by design.
Accessible to Everyone
No account means no barrier. Works in any browser, on any device, anywhere in the world.
⚙️ How Local Processing Works
Web Crypto API
Password generation and hashing use your browser's native crypto.getRandomValues and crypto.subtle — the same APIs trusted by banking apps.
Canvas API
Image compression and EXIF removal re-render images through an HTML Canvas element entirely in memory. Nothing reaches our servers.
File API
Files you drop or select are processed as ArrayBuffer or DataURL objects in JavaScript — never transmitted over any network connection.
📊 By the Numbers
