qrshare

qrshare is a command-line tool designed to facilitate the transfer of files, folders, or text from a computer to a phone over a local WiFi network. It operates by serving the selected content from the user's machine and generating a QR code, which can be scanned by the phone to initiate the transfer. The process is conducted entirely within the phone's browser, requiring no additional app, account, or cloud service.

The tool supports several modes, automatically detecting whether the user is sharing a file, folder, or text, with the option to force a specific mode using command-line flags. When sharing a file, qrshare streams the data directly, allowing for transfers of any size without loading the entire file into memory. For folders, the contents are zipped on the fly and streamed to the phone, again avoiding buffering to disk. The server hosting the content shuts down automatically after the download is complete. qrshare also provides an inbound mode, enabling users to receive files from their phone to their computer by scanning a QR code that opens an upload page in the phone's browser. Additionally, text or URLs can be shared by piping them into the command or passing them as arguments, with the phone displaying the text and offering a one-tap copy button.

All transfers occur directly between devices on the same WiFi network, ensuring that no data is routed through the internet. The tool is delivered as a command-line executable and does not mention any associated costs or licensing details in the provided evidence. qrshare is positioned as a solution for users seeking a straightforward, app-free method to move data between their computer and phone using their local network.
