iOS 27 Download: Direct Links for Every iPhone and iPad

iOS 27 and iPadOS 27 are rolling out today, September 14, and the direct IPSW firmware files are already live on Apple’s servers. If you’d rather skip the over-the-air download or you’re restoring a device that’s stuck, this is the fastest path to the finished release. Apple confirmed the release date at last week’s “Surprise and Shine” event, where it also introduced the new iPhone 18 Pro lineup. Both updates ship as build 24A437, the finished version Apple built out of the Release Candidate it handed to developers and public beta testers on September 9.

What’s new in iOS 27 and iPadOS 27

The headline feature is Siri AI, Apple’s rebuilt assistant that can hold real conversations, pull context from Messages, Mail, Photos and Notes, and answer follow-up questions without you starting over. It’s rolling out in English first, and it won’t be available on iPhone or iPad in the EU at launch. Beyond Siri, iOS 27 brings a Liquid Glass transparency slider, faster app launches and AirDrop transfers, and Photos editing tools like Spatial Reframing and a bigger Clean Up tool. iPadOS 27 gets the same Apple Intelligence upgrades plus faster file transfers to external drives. For the full rundown, see our iOS 27 feature guide and iPadOS 27 feature guide.

How to download iOS 27 and iPadOS 27

The easiest route is still over the air:

Open Settings on your iPhone or iPad
Go to General > Software Update
Tap Download and Install

If you’d rather use a computer, plug your device into a Mac running macOS Catalina or later and update through Finder, or use the Apple Devices app on a PC. Back up your device first. It’s the one step people skip and then regret. If you need the standalone IPSW file instead, Apple hosts these directly on its CDN, and you’ll find direct links for your specific device model below. Manual installation is mainly useful if you’re restoring a device or an OTA update won’t complete.
