In their own words
USBImager
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.
