Etcher copies images to drives byte by byte, without doing any transformation to the final device, which means images that require special treatment to be made bootable.
Etcher, now named balenaEtcher, is a free and open-source application used for burning ISO and IMG files, and also zipped folders to USB drives and SD cards. This tool is available for Linux, Windows and macOS and that too with the same UI so that you get the same user experience everywhere. So, whenever you want to burn a flash drive or even a microSD card, you can rely on Etcher as your go-to tool. We have tried to explain a step-by-step process for installing and using Etcher so that the USB burning/flashing process becomes even simpler for you. We are taking the Ubuntu 18.04 LTS ISO file as an example, downloaded from the Internet, to describe the entire process for you. You may visit: https://www.etcher.net/
