Overview
balenaEtcher, from balena, is a focused image-writing tool: select an image file, select a target drive, flash. It's widely used for writing Raspberry Pi OS images to SD cards and for burning Linux ISOs to USB drives, though it works for any raw image or ISO you need written to removable media.
Its interface is deliberately minimal compared to Rufus, with fewer configuration options but a strong safety feature: it validates the write by reading back the flashed drive afterward, and it actively tries to prevent you from selecting your system drive as the target.
Unlike Rufus, balenaEtcher does not offer Windows-to-Go creation, partition scheme customization, or Windows ISO-specific options — it's a general-purpose flasher, not a Windows installer specialist. For creating a Windows installation USB with fine-grained control, Rufus remains the more common choice.
It's cross-platform (Windows, macOS, Linux), which makes it convenient if you regularly prepare boot media from more than one type of computer.

How to use it
1. Select an image
Click 'Flash from file' and choose your ISO or image file.
2. Select the target drive
Confirm the correct USB drive or SD card is selected — double-check size and label to avoid picking the wrong device.
3. Flash and verify
Click Flash; balenaEtcher writes the image and then automatically verifies the write before reporting success.
Safety and privacy
- Download only from etcher.balena.io or the project's official GitHub releases.
- Flashing an image completely erases the target drive — double-check drive selection before confirming.
- Bundled software
- The official installer does not bundle third-party offers.
- Privacy
- Runs locally; flashing does not require an account.
Known risks
- As with any imaging tool, selecting the wrong target drive erases its existing contents — verify drive size and label before flashing.

Frequently asked questions
Is balenaEtcher free?
Yes, it's free and open source under the Apache 2.0 license.
Can balenaEtcher create a Windows installer USB?
It can flash a Windows ISO to a USB drive, but it lacks Rufus's Windows-specific options like partition scheme selection and Windows-to-Go, so Rufus is generally the better tool for that specific job.
Does balenaEtcher verify the write was successful?
Yes, it automatically reads back the flashed drive after writing to confirm the data matches the source image.
