“What is an IPSW file? What can an IPSW file do for me? Do I need to install IPSW file with iTunes or 3rd-party IPSW installer tools? Please explain this for me.”

For those people who have restored their iPhone, iPad or iPod quite often, IPSW is no stranger. However, for those regular users of iOS devices (including iPhone, iPad and iPod), IPSW might be a quite rare thing. In this guide, we would like to explain what IPSW file is and what IPSW file can do for us.

Part 1: What is IPSW file and what can IPSW file do?

An IPSW file is one used by Apple Inc. to add new features, restore software on a device to its default factory settings and, at times, address security loopholes in iOS devices - iPhones, iPods and iPads- compatible with the release. With it, iOS device (iPhone, iPad and iPod) owners can install the firmware update or downgrade, which is released in an archived, compressed format, through iTunes on either Windows or Mac. When decompressed, the files hold PLISTs, BBFWs, DMGs, IM4Ps files among others, all of which are encrypted.

When a compatible device (iPhone, iPad and iPod) connected to a computer is in need of an update, an IPSW file can be downloaded automatically through iTunes after accepting a prompt to update the device. iTunes will then apply the IPSW file to the device.
Since these files are stored as ZIP archives, you can also open an IPSW file using a file zip/unzip tool, such as the free 7-Zip. You could then see the different DMG files within the IPSW file, but you can't apply the software update to your Apple device this way — iTunes still needs to use the IPSW file.
The IPSW is an archived file format and can, therefore, be converted easily by using any unzip software. However, there shouldn't be any reason to convert an IPSW file to another format. The way it exists is necessary for communicating software updates through iTunes and to Apple devices; converting it would mean losing functionality of the file altogether.

Part 2: Where can I download IPSW file and where IPSW file locates

As mentioned above, when you connect an iOS device (iPhone, iPad or iPod) to iTunes and choose to update your iOS device firmware, iTunes would automatically download IPSW file for your device connected. Apple always releases new IPSW files through iTunes, but you could still download current and outdated firmware versions of IPSW file websites like IPSW Downloads.
Check the below table to learn where IPSW file locates on your computer.

Part 3: How to install IPSW file with/without iTunes

Install IPSW file with iTunes

You could directly install IPSW file for your iOS device (iPhone, iPad and iPod) with iTunes. If you've obtained an IPSW file through iTunes in the past or have downloaded one from a website, you can just double-click or double-tap the IPSW file to open it in iTunes. The IPSW files have been saved in different folders according to your computer system, as mentioned in the above content.

Another way to install an IPSW file with iTunes is by forcing it to use the file of your choice. For Mac users, launch iTunes, select your phone on the left sidebar hold down the Alt/Option key and click on restore so as to browse downloaded IPSW file for restoring.

Bonus: Back up iPhone data before installing IPSW file

Well, now we have learned that IPSW file is actually an iOS device update file that would help you easily update your iOS firmware. Once you have connected your iOS device (iPhone, iPad, and iPod) to iTunes and install IPSW file on iTunes, your iOS device will be updated. However, as known to all, there is a risk of data loss during iOS device firmware update. Therefore we would like to highly recommend you back up iOS device (iPhone, iPad and iPod) before you install IPSW file with or without iTunes.

You could freely back up iOS device with iTunes and iCloud, either of which will help you back up your iPhone, iPad or iPod as an entire backup file for you to restore in the future. However, you should know that with iTunes or iCloud, you can’t back up iOS device (iPhone, iPad and iPod) selectively. That means you have to back up data and files from iOS devices you don’t want to keep into iTunes or iCloud. Is there any way to back up iPhone data with preferred data and files kept only?

Try Leawo iTransfer.
