About
We built the tools we wished existed.
Every day, millions of people upload sensitive files to free online tools — trusting strangers with their data because there's no alternative. We built one.
The Problem
Free tools aren't free.
We analyzed one of the most popular online PDF tools. What we found: 637 cookies set on a single visit. 221 third-party domains contacted. Session recording software watching every click. Your files processed on someone else's server.
This isn't an outlier — it's the industry standard. The “free” model depends on harvesting your data. We think there's a better way.
How It Works
Three principles, zero compromise.
Local-first
Your files never leave your device. Every conversion, every edit, every transformation happens right in your browser using WebAssembly and modern web APIs.
Transparent
Our analytics are open source. We track page views and tool usage — that's it. No cookies, no fingerprinting, no personal data. Check our transparency page to see exactly what we collect.
Open Source
Every line of code is on GitHub. Audit it, fork it, improve it. Privacy claims are only as strong as the code behind them.
The Exception
One tool that needs a server.
The Privacy Auditor is the only tool that doesn't run locally. It uses a server-side headless browser to visit websites and analyze their tracking behavior — something that's impossible from a client-side context.
It loads the target page in Puppeteer, waits for all resources, then counts cookies, third-party domains, and known trackers. The result is a privacy grade from A to F, with a detailed breakdown you can share.
Even here, we minimize data collection: your IP is hashed and discarded, scan results are cached for 24 hours, and no account is required.
Open Source
MIT licensed. Always.
Privacy claims without transparency are just marketing. That's why Uploadless is fully open source under the MIT license. Read the code, verify our claims, or build on top of it.
