Why EasyFileKit is different

Most “free” tool sites upload your file to a server, process it, then send it back. We don't. Here's the difference.

Private by design

All processing happens locally via JavaScript & WebAssembly. Open DevTools → Network — you'll see zero file uploads. Ever.

Instant

No upload wait, no queue, no server round-trip. Results appear the moment you drop a file.

Free & unlimited

No accounts, no watermarks, no daily caps. Use every tool as many times as you like, forever.

Works everywhere

Desktop, tablet or phone — every tool is responsive and installable as a PWA for offline use.

Verify it yourself

“Your files never leave your device” — here's the proof

We turn our privacy promise into a marketing weapon no server-based competitor can copy. Don't take our word for it — verify it in 30 seconds.

  1. Open this page in your browser and press F12 to open DevTools.

  2. Switch to the Network tab and tick “Disable cache”.

  3. Use any tool — merge a PDF, compress an image, anything.

  4. Watch the Network log: only static assets load. Your file never leaves the device.
