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.
“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.
Open this page in your browser and press F12 to open DevTools.
Switch to the Network tab and tick “Disable cache”.
Use any tool — merge a PDF, compress an image, anything.
Watch the Network log: only static assets load. Your file never leaves the device.
