Quick Share is file transfer software enabling secure, end-to-end encrypted sharing across devices. It supports LAN transfers for offline, peer-to-peer sharing within local networks and cloud transfers via links for remote sharing. Local transfers work without internet, keeping files on devices and bypassing external servers. Compatible with Android, iOS, Windows, macOS, and Linux, Quick Share offers web-based and native apps, with the web version requiring no installation. Transfer speeds range from 10 to 100 MB/s on Wi-Fi, with faster speeds on wired connections. Features include automatic device discovery, group sharing, and interrupted transfer resumption. Local transfers have no file size limits, constrained only by storage and network stability. Quick Share prioritizes privacy, avoiding tracking, data collection, and ads. Files shared locally never reach external servers, ensuring confidentiality. Multiple devices can share simultaneously on the same network.
