Fedora Media Writer vs USBImager

Fedora Media Writer creates bootable USB drives by writing Fedora images to them. It runs on Linux, macOS, and Windows, and can download the image before writing. A Live Fedora drive can be booted to try Fedora without making permanent changes to the computer. Getting started requires a 4GB USB flash drive.

Writing uses direct access to the device and replaces its existing contents and partition layout. Fedora Media Writer includes a Restore feature to put the drive back into a standard single-partition layout. Image checks can include comparing the USB device with the downloaded ISO or booting it and running a media check. Fedora also advises verifying downloaded images with a checksum file signed by a Fedora Project OpenPGP certificate. Installation options include Fedora's RPM package, Flathub on Linux, Windows releases, and a macOS DMG. The project identifies the software as GPL-2.0 licensed and directs users with crashes or writing errors to open a GitHub issue. It is free: free.

USBImager is a free desktop utility for writing disk images to USB drives and creating backups. It reads raw images, compressed formats such as .gz, .bz2, .xz, and .zst, and archives including .zip, .tar, .cpio, and .pax. It can compare a written drive with the source image to verify the result, and create backups in raw or ZStandard compressed format. Images can also be sent to microcontrollers over a serial line. The app is available for Linux, macOS, and Windows, with a minimalist native interface and 18 language options. The maker says it is intended for people who may be uncomfortable with command-line tools, and that it tries to avoid overwriting the system disk. Synchronized writes are intended to ensure data is on disk when progress reaches 100%. The maker describes it as free of advertisements and privacy concerns and GDPR compatible. One stated limit is that xz compression dictionaries larger than 1 gigabyte are unsupported. The app is open source under the MIT license.
