Etcher: Flash OS Images Safely and Easily Across Devices

Etcher, or balenaEtcher as some call it, is an application you can get for free that makes it easier to put operating system images onto SD cards and USB sticks. It has a user-friendly design and strong features which make it perfect for both new people just starting out and those who have more experience when they need to set up operating systems or recovery software on portable devices.

Introduction: A User-Friendly Approach to Flashing

Etcher was developed by Balena. Etcher is a free, open-source tool that allows users to write images to portable storage media such as USB sticks and SD cards. Flashing refers to writing an operating system or software image onto a storage device like an SD card or USB drive. Traditionally, this process could be complex and risky, requiring specialized tools and knowledge. Etcher was developed using the Electron framework and supports Windows, macOS and Linux.
