USBImager

Overview

USBImager is a small, open-source GUI tool for writing and reading raw disk images to/from USB drives. It’s designed to be minimalist, portable, and cross-platform (Windows, macOS, Linux, Raspberry Pi).

Key features

• Write images: Writes .img/.iso/.raw/.dd and similar raw images to USB drives.
• Read/create backups: Can create raw and bzip2-compressed backups from USB devices.
• On‑the‑fly compressed/archive support: Reads compressed images (.gz, .bz2, .xz, .zst) and ZIP archives without manual decompression.
• Verify writes: Option to verify the written data by comparing image to device.
• Synchronized writes: Ensures data is flushed to disk before reporting completion.
• Small & portable: Tiny single-file executables with no heavy dependencies; often distributed as standalone ZIPs or native packages.
• Cross‑platform native UI: Native frontends for Windows (GDI), macOS (Cocoa), and Linux (GTK/X11).
• Safety checks: Attempts to avoid overwriting system disks; has flags for advanced use (list all devices, force, etc.).
• Open source license: MIT-licensed (primary upstream project).

Typical use cases

• Creating bootable USB installers from OS images.
• Backing up USB drives to compressed images.
• Flashing firmware or images for embedded devices and Raspberry Pi.
• Quick, privacy-focused alternative to larger tools like BalenaEtcher.

Where to get it / docs

Official project repositories and releases are available (example upstream: GitLab repo by bztsrc and forks on GitHub). The repos include small downloadable executables, a manual, and usage flags/CLI options.

Quick safety tips

• Always double-check the target device before writing — data loss is irreversible.
• Prefer using
