Etcher is an open-source cross-platform tool for burning images to SD cards, USB drives and other removable devices.
The program keeps operations to the bare minimum, all of them clearly displayed on a simple interface. Choose your image, then your drive, and finally click the “Flash!” button.
Etcher supports many different image formats: ISO, IMG, RAW, BZ2, DMG, DSK, ETCH, GZ, HDDIMG, XZ and ZIP.
The program burns images only and can’t compete with more versatile products, but does at least warn you of this. We chose a Windows image, for instance, and Etcher warned us that extra processing was required to make the image bootable, and we should use a tool like Rufus instead.
The “Choose a drive” step only enables selecting removable devices, reducing the chance that you’ll accidentally trash a system drive. If this doesn’t suit your needs – maybe a removable device isn’t being detected correctly – you can disable this protection by turning on “Unsafe Mode” in settings.
Once the image is written, Etcher validates the results to make sure it’s worked correctly. That’s usually a good idea, but can take a while, and if you prefer you can disable validation in Settings.
The program can also burn the same image again immediately afterwards, handy when you’re working with a batch of drives.
Overall, while it’s not doing anything too clever, Etcher is a convenient and easy-to-use image burner which works almost everywhere. And that’s just fine with us.
Etcher is an open-source tool for Windows 7 and later, Linux and Mac.
