Etcher is a cross-platform OS image flasher that writes disk images to SD cards and USB drives with safeguards against data loss.
The tool solves the problem of safely flashing operating system images to removable media. It protects users from accidentally writing to hard drives, verifies that every byte was written correctly, and provides a graphical interface built with web technologies to make the process straightforward. The tool can also directly flash Raspberry Pi devices that support USB device boot mode.
Etcher suits anyone who regularly writes OS images to SD cards or USB drives, from hobbyists working with single-board computers to system administrators managing multiple devices. It runs on Linux, Windows, and macOS, including Apple Silicon machines. The tool is available through multiple package managers and distribution channels across all supported operating systems, making installation straightforward regardless of platform.
The project maintains steady development activity with regular updates across its codebase. The tool receives ongoing maintenance through automated package updates on Windows platforms. Documentation and support infrastructure remain actively managed, with a public roadmap available for users to track planned improvements. The project accepts community contributions and maintains clear channels for bug reports and feature requests.
