How to download and use Apple IPSW files

Your Apple device automatically downloads IPSW files when you perform an update via Finder, iTunes, or Software Update. These OS images are essential for the software update process, restoring iPhone to factory default settings, etc.


You can manually manage, explore, and install IPSW files with third-party tools. Follow our guide to learn how IPSW files work, where to download them, and how to use IPSWs to update or downgrade the operating system software that powers your Apple devices.


What are IPSW files? What are they used for?

IPSW (short for iPhone Software) is Apple’s proprietary file format for packaging and delivering iOS and iPadOS firmware updates.

IPSWs hosted on Apple’s servers typically have various improvements, bug fixes, and security updates. These files are required to restore, update or downgrade the software on your iPhone and iPad.

A file with the .ipsw extension is a renamed ZIP archive that contains at least three encrypted volumes in the Apple Disk Image (DMG) file format, along with other installation files, property lists, bootloader, baseband firmware, and so on.

A DMG holds the file system for an entire operating system. The remaining DMGs provide RAM disks for the recovery and update processes.

How to download iOS firmware update files

If automatic updates are enabled in Settings, iPhone will fetch new IPSW files as soon as Apple sends them live. Performing updates via iTunes or Finder will automatically download the appropriate IPSW files to a special folder on your computer.

The IPSW archive is stored in your computer’s Downloads folder, so use Finder or File Explorer to explore its contents. You can safely rename IPSW and discard, copy or move it like any other file. Do not worry; deleting downloaded IPSWs will not harm your Apple device.

People who use automatic updates or the software update feature do not need to worry about IPSWs. However, if you want to flash or downgrade your Apple device manually, you will need to obtain the correct IPSW file for your hardware from one of the following sites:

  • IPSW Downloads: The most comprehensive site for IPSW downloads because it provides links dating back to the original iPhone.
  • iDownloadBlog: Apart from IPSW download links, iDownloadBlog hosts jailbreak resources and tools like Evasi0n, Absinthe, RedSn0w, etc.
  • iClarified: iClarified maintains download links for every released IPSW, each tagged with iOS version number and device model.
  • iOS Ninja: Direct IPSW download links for iOS, iPadOS and tvOS firmware updates sorted by device category, model and version.
  • iJunkie: IPSWs for all iPhone software updates released so far.

Multi-gigabyte IPSW downloads can eat up storage space. After updating the device, discard the IPSWs to avoid running out of disk space.

Please respond positively to download the latest IPSW so you don’t have to. Your computer will then install the update on the connected device.

Want to downgrade to an older iOS version? If so, you need to download the correct IPSW file. Then connect your device to your computer’s USB port, launch iTunes or Finder, select your device in the sidebar, and hold Shift (Windows) or Option (Mac) while clicking Restore button. Finally, select the downloaded IPSW file and click Open.

The recovery process will erase all data, reinstall a fresh copy of the latest iOS version, and load factory settings. You can also restore an iPhone or iPad from a backup to avoid losing anything, but be sure to back up your iPhone using either iCloud or your computer beforehand.

Before downgrading, you may need to put your iPhone or iPad into DFU mode. Apple restricts IPSW signing to prevent downgrades to older OS versions that lack the latest security protections. To recover unsigned IPSWs, use the specialized third-party software mentioned just ahead.

The best apps for managing IPSW archives

Aside from iTunes and Finder, the free Apple Configurator app will not only let you install IPSWs, but also quickly deploy multiple devices with custom settings, apps, firmware, and data.
