How CompressNFly Works — No Uploads Required
Most online tools upload your file to their server. Your file passes through infrastructure you have no control over. CompressNFly uses WebAssembly to run all compression inside your browser. Your file never moves — selected on your device, compressed on your device, downloaded to your device.
Faster
No upload/download overhead. Files under 20MB compress in milliseconds.
Private
Your file never leaves your device. Not even for a millisecond.
No Account
Nothing stored on a server means no account needed.
