What is balenaEtcher?

balenaEtcher is a free, open-source tool for writing disk images such as ISO and IMG files to SD cards and USB drives. It walks users through a simple three-step process (select image, select drive, flash) and validates every write to confirm the resulting media will boot correctly, removing the guesswork from creating installation or recovery media. Built with Electron and maintained by balena, Etcher hides system drives by default to prevent accidentally overwriting a hard drive, works identically across Windows, macOS, and Linux, and is used for everything from installing Raspberry Pi operating systems to building bootable Windows or Linux installers.
