just f***ing send it

just f***ing send it (jfsendit) is a dead-simple peer-to-peer file transfer tool that lets you send any file directly from one browser to another. There is no upload to a server, no account creation required, and no middleman storing your data. It is designed for anyone who needs to share files quickly and privately without the hassle of cloud storage or email size limits. The core value is absolute simplicity: open the site, choose a file, share a one-time code, and the transfer happens directly between devices over an encrypted WebRTC connection.

Traditional file sharing often involves uploading to a third-party server, waiting for processing, and trusting that server with your data. Users face file size limits, expired links, and the friction of account sign-ups. This tool solves those pain points by eliminating the server entirely. Transfers are direct device-to-device, so no file ever touches a remote machine. This matters for large files, sensitive documents, and users who value privacy. The one-time code also ensures that only the intended recipient can access the transfer, and the code expires after use or timeout.

The first major feature is direct browser-to-browser transfer using WebRTC. When you send a file, the site generates a short, unique code. The sender shares this code with the intended recipient via any channel. The recipient enters the code, and the two browsers establish a secure peer-to-peer connection. All data flows directly between them over an encrypted DTLS tunnel. This means the bytes never pass through or get stored on a server—only a tiny code-exchange happens on the site to introduce the two browsers. The result is fast, private, and serverless file transfer.

The second major feature is the absence of any file size limit and the ability to send folders as a single .zip file. The site explicitly states that multi-gigabyte files work fine. When you drop a folder onto the page, it streams across as one .zip archive, preserving the folder structure. Data streams straight to disk, so nothing has to fit in memory. This is particularly useful for sending large video projects, design asset packs, or backup archives without worrying about memory constraints or splitting files. The recipient receives the complete folder as a single downloadable file.

The third feature group includes one-time codes, end-to-end encryption, and resumable transfers. Codes are short-lived and can only be used once—whoever connects first with a valid code becomes the receiver, and the code is immediately consumed. WebRTC encrypts everything end-to-end (DTLS) by default, so the service provider cannot see, scan, store, or recover any file content. If the connection drops mid-transfer, it automatically reconnects and resumes from the exact byte it left off, as long as the sender keeps the tab open. Both devices must remain awake for the entire transfer to complete.
