ButterShare

ButterShare is a secure browser-based peer-to-peer file sharing tool that lets you send large files directly between devices without uploading them to cloud storage first. It works across Windows, Mac, Linux, Android, and iPhone through the browser, so there is no app to install and no account required. Users can select a file, generate a share link or QR code, and open it on the receiving device to begin the transfer. ButterShare is especially useful for large videos, RAW photos, project files, backups, and cross-platform transfers such as iPhone to Windows or Android to Mac. ButterShare uses WebRTC for direct device-to-device transfers when possible, reducing unnecessary cloud storage and making file sharing simpler and more private.
