The Privacy-First PDF Toolkit(That Literally Can't See Your Files)
Most free PDF tools have a dirty secret.
To merge, compress, or convert your file, they force you to upload it to their servers.
And once that file leaves your computer? You lose control. You don't know who sees it. You don't know where it's stored. And you don't know if it's ever been deleted.
That is why we built PDFOutfit.
We developed the web's first LocalCore™ toolkit.
The result? We bring the processing power to you. Your tax returns, legal contracts, and medical records never leave your browser.
Here's how we did it.
The "Privacy Gap" Architecture
We didn't just want to make another PDF editor. We wanted to solve the privacy problem for good.
So we built LocalCore™.
It's a proprietary engine powered by WebAssembly (WASM). Think of it as a privacy shield between your browser and the internet.
Here's the deal:
When you drop a file into PDFOutfit, the code runs 100% inside your device's memory.
No POST requests. No cloud uploads. We literally cannot see your files.
You can literally turn off your Wi-Fi after the page loads. It still works.
Why It Matters
GDPR Compliant by Default
Since we never collect, store, or transmit your data, we (and you) are automatically compliant. We can't lose your data because we never had it.
Zero Latency (It's Fast)
Competitors make you wait for uploads and downloads. LocalCore is instant. It starts processing the millisecond you drop the file.
Don't Trust Us. Test Us.
We know "privacy" is a buzzword. So we want you to verify it yourself.
Watch the "Network Tab" Challenge:
Watch: The Network Tab shows zero file uploads during PDF processing
The "Network Tab" Challenge:
- 1Open our Compress PDF tool
- 2Right-click anywhere on the page → Inspect
- 3Click the "Network" tab in the panel that opens
- 4Drop your PDF (e.g., a 5 MB file) into the tool
Here's what to look for:
Other PDF tools:
You'll see a row pop up with a huge file size (e.g., 5.2 MB). That's your document being sent to their server.
PDFOutfit:
Zero document uploads. You might see tiny background scripts loading (0.4 kB) or analytics pings, but you'll never see your 5 MB file transfer.
Your document stays 100% on your device.
We believe trust shouldn't be a promise. It should be verifiable.
