This article explains what an IPSW file is, the different ways to use it, and how to download it to your device.

What is an IPSW file?

A file with the IPSW file extension is an Apple device software update file used with iPhone, iPod touch, iPad, and Apple TV. It is a file format that stores encrypted DMG files and various others such as PLISTs, BBFWs, and IM4Ps.

IPSW files are published by Apple and are intended to add new features and fix security vulnerabilities on supported devices. They can also be used to restore an Apple device to its factory default settings.

Apple always releases new IPSW files via iTunes. You can also get updated firmware versions for iOS, iPadOS, watchOS, tvOS and audioOS through sites like IPSW Downloads. There are still older versions from several years ago, including older iTunes versions.

How to open IPSW file

When a compatible device connected to a computer needs to be updated, an IPSW file can be downloaded automatically via iTunes after accepting the device update request. iTunes will download the file to the device.

How to download and install new iOS updates

If you have received an IPSW file through iTunes in the past or downloaded it from a website, double-click or double-tap the file to open the file in iTunes.

When downloaded by iTunes, the file is saved in the following location:

IPSW file locations
Windows 11/10/8/7
iPhone:C:\Users\[username]\AppData\Roaming\Apple Computer\iTunes\iPhone Software Updates
iPad:C:\Users\[username]\AppData\Roaming\Apple Computer\iTunes\iPad Software Updates
iPod touch:C:\Users\[username]\AppData\Roaming\Apple Computer\iTunes\iPod Software Updates
Windows XP
iPhone:C:\Documents and Settings\[username]\Application Data\Apple Computer\iTunes\iPhone Software Updates
iPad:C:\Documents and Settings\[username]\Application Data\Apple Computer\iTunes\iPad Software Updates
iPod touch:C:\Documents and Settings\[username]\Application Data\Apple Computer\iTunes\iPod Software Updates
macOS operating system
iPhone:~/Library/iTunes/iPhone Software Updates
iPad:~/Library/iTunes/iPad Software Updates
iPod touch:~/Library/iTunes/iPod Software Updates

“[username]” Windows paths should be replaced with your own user account name. if you can’t find Application Data folder, you may need to change the hidden file settings in Windows.

Another way to install an IPSW file with iTunes is to force it to use the file you chose. To do this, hold Change (Windows) or Choice (Mac) and hit the restore button in iTunes. From there, select the IPSW file you want to install on the device.

You can also upload IPSW files. without iTunes, but most of the methods are only available through non-free software such as iMyFone Fixppo, Tenorshare ReiBoot, and iMobie AnyFix.

If an update is not working properly or iTunes is not recognizing the downloaded file, you can delete it or uninstall it from the above location. This will force the program to download the file the next time it tries to update the device.

Since these files are stored as ZIP files, you can also open an IPSW file using a file zip/unzip tool; The free 7-Zip is an example. This will allow you to see the different DMG files that make up the IPSW file, but you cannot apply the software update to your Apple device that way – iTunes will still need to use it.

If you find that an application on your computer is trying to open the file but it’s the wrong application, or you prefer another installed program to open the file, learn how to change the file associations in Windows to make that change.

How to convert IPSW file

There should be no reason to convert an IPSW file to any other format. The form is required in its current form to communicate software updates via iTunes and Apple devices; converting it means completely losing the functionality of the file.

If you want to open an Apple Firmware Update file as a compressed file, you don’t have to worry about converting IPSW to ZIP, ISO, etc. – as you read above, use a file opener to open the file.

Still can’t open?

Some file formats use similarly written file extensions, which can be confusing when you have trouble opening the file. While the two file extensions may look similar, that doesn’t necessarily mean they are of the same or similar format, which of course means that they cannot be opened with the same software.

For example, patch files in the built-in patch system use the IPS file extension, which is very similar to IPSW. However, even though they share three of the same file extension letters, they are actually completely different file formats. IPS files are opened with Internal Patch System software such as IPS Peek.

PSW files can also be easily confused with IPSW files, but they are actually Windows Password Reset Disk files, Password Depot 3-5 files, or Pocket Word Document files. None of these formats have anything to do with Apple devices or the iTunes program, so if you’re unable to open your IPSW file, double-check that the file extension doesn’t read “PSW.”

Another similar is IPSPOT, which is used by the Photos app for macOS for iPhoto Spot files.

If your file doesn’t end in IPSW, search for the file extension you see after the filename – here on Lifewire or elsewhere like Google via the search tool at the top of this page – to learn more about the format and which program can open or convert it.

If your file doesn’t actually end with IPSW, research the file extension you see after the file name—either here on Lifewire via the search tool at the top of this page or elsewhere like Google—to learn more about the format and what program is capable of opening or converting it.
