Sylveris Transfer is a pure front-end peer-to-peer file transfer tool built on WebRTC technology. No registration, no installation, no server storage.
Traditional approaches load the entire file into browser memory, limited by device RAM. Sylveris uses the Streams API for streaming transfer: the sender reads and sends chunks on the fly, while the receiver writes directly to disk. In theory, files of any size can be transferred.
Transfers use native WebRTC DTLS encryption. We do not store files, keep logs, or collect personal information.
Streaming disk writes require Chrome/Edge 86+ (File System Access API). Unsupported browsers automatically fall back to memory mode; we recommend keeping files under 2GB in those cases.
