About JustDropFile
Our Mission
Almost every "send a file" service is really a storage service with a download link. Your file sits on their disks, gets scanned, has an expiry date, and depends on their policies. For a lot of files that is fine. For the ones that are not, there was no simple browser tool that just moved the bytes from one device to the other and kept nothing.
JustDropFile is that tool. It does one thing: send files straight from your device to theirs.
How It Works
The two browsers connect to each other with WebRTC, the technology behind browser video calls. Our only server-side piece is a tiny signaling service that passes connection details between them so they can find each other. Once connected, the file streams directly, in small encrypted pieces.
Privacy First
The encryption key lives in the part of the link after the # sign, which browsers never send to any server. So even the pieces of infrastructure we do run cannot read what goes through them. This is not a policy promise; it is how the thing is built.
Open and Transparent
You can verify this yourself in the network tab of your browser's developer tools. The only server connection you will see is the small signaling connection that introduces the two browsers. Your files never go through it.
