win32diskimager.app is a reference website about Win32 Disk Imager. It is not affiliated with, endorsed by or sponsored by the Win32 Disk Imager project, its original author, the ImageWriter developers, the authors of the native Win32 rewrite, or any other third-party platform mentioned on the website, including GitHub, SourceForge and Microsoft.
We don't develop, maintain or distribute the software. Where we refer to official files, we link to the places where their maintainers publish them.
Downloads come from third parties
Download buttons on this website link to files hosted by others. The main download is the source archive of the native Win32 edition, hosted on GitHub. The original installer and binary ZIP are hosted on the SourceForge project.
We don't control those files and can't guarantee that they are free of defects, that they will stay available, or that they will be unchanged in future. Before running any download:
- check that the address belongs to the expected host;
- compare published checksums where they're provided;
- scan it with up-to-date security software.
Information only
Our guides, comparisons and troubleshooting steps are written for general information. They reflect our testing on particular hardware and Windows versions at the time of writing. Your system, card reader, storage media and images may behave differently.
Nothing on this website is professional advice. For business-critical systems, such as industrial controllers or medical or laboratory equipment, follow the equipment manufacturer's procedures first.
Data-loss warning
Win32 Disk Imager writes directly to storage devices. A write permanently replaces everything on the selected device, and choosing the wrong device can destroy data. Reading a card can fail on damaged media. We're not responsible for any loss of data, damage to media or equipment, or downtime resulting from use of the software or of information on this website.
Always:
- back up anything you may need before writing;
- confirm the target device's letter and size;
- verify writes that matter.
Lawful use
Use the software only with images and media you own or are authorised to copy. Some disk images, such as commercial firmware or operating systems, are covered by licences that restrict copying. Respecting those licences is your responsibility. The website doesn't host or provide disk images.

Our descriptions are based on publicly documented features and our own testing at the time of writing. Those products change, and their makers may add or remove features. Check their official documentation for current details. Mentioning a product isn't an endorsement, and we receive no payment for doing so.
