Cydia Impactor download for Windows, Mac, and Linux.
What is Cydia Impactor?
Cydia Impactor is a free application mostly used to install IPA files on iOS devices, sideload APK files on Android system and exploit the series of Android "Master Key" vulnerabilities. After downloading the right version for Windows, Linux, or Mac you need to extract the file and you are ready to go.
Impactor is known in the jailbreak community as the tool to sideload IPA files. An .IPA file is an iOS application archive file which stores an iOS app. Each .IPA file includes a binary for the ARM architecture and can only be installed on an iOS device. .IPA files can contain jailbreak tools, apps, and games, etc.
Install Cydia Extender. This app runs on iOS 11 and registers to handle IPA files, allowing you to browse in Safari directly to an IPA file and install it using the same mechanisms used by Cydia Impactor. It also can re-sign and reinstall itself. ReProvision app offers the same features for iOS 12 and iOS 13.
With Cydia Impactor 0.9.51, it is easy to sideload apps. The user needs just to plug the device (iPhone, iPad, iPod) into the computer (USB driver), select an IPA file, enter Apple ID an app-specific password. Install IPA files without jailbreak on any iOS 11, iOS 12, and iOS 13 device.
Download Cydia Impactor for free.
After it, the tool will prepare the app, sign the IPA file, and sideload the app on your iOS system. If everything goes as expected, the sideloaded IPA will be installed on your iOS 12 device. Remember to always update Impactor to the newest version to avoid any errors.
There is also a need to go to Settings → General → Device Management and trust the certificate of the installed app. Recent Cydia Impactor 0.9.52 update offers full support for macOS Catalina. This version is also available for download from our software hub.
The software features options to install package, reboot the device, open shell, run a program, test backup, activate bootloader, delete App ID, revoke certificates, boot image, lock and unlock the device, download AOKP, get identifier token, or debug the device (iOS).
How to sign IPA using Cydia Impactor
If you are using the Apple ID registered with Apple’s Developer Program, you will use the developer certificate which will remain valid for one year. In case you are using a non-developer ID, you can generate and use 7 days validity certificate only. I will walk you through the process.
Step 1. Download Cydia Impactor, and unzip the file.
Step 2. Install the newest version of iTunes.
Step 3. Connect your device. Open Cydia Impactor and navigate to Device → Install Package.
Step 4. Select the .IPA file to install.
Step 5. Enter your AppleID and app-specific password to sign apps not provided by Apple.
The required password for Cydia is not the one you use for AppleID login. Follow the next steps to generate an app-specific password from Apple if you don't have one.
1. Login to appleid.apple.com.
2. Click Generate Password... in the Security section.
3. Add the label "MyApp" to the popup and click Create and copy the password.
Step 6. The sideloaded iOS app should be visible on the home screen.
Step 7. Next, add your certificate to trusted from Settings → General → Device Management.
Now you can run the application from the home screen. After the certificate expired, your app will crash every time you try to open it. You will need to repeat all steps to sing iOS application again.
Cydia Impactor 0.9.52 is broken by a server-side change at Apple on 7 October 2019. The app will not sign IPA files anymore. The developer needs to fix submitDevelopmentCSR error and update Xcode 7.3 or later to continue developing with your Apple ID.

In "APP-SPECIFIC PASSWORDS" we will Generate Password for our app. We can name it how we prefer. Cydia Impactor will then ask us about Apple ID and password for this app.
Stuck on VerifyingApplication message can be also a problem for some of the users. To fix this kind of problem we need to do one of a few things to make it work.

Saurik did a great job creating Cydia Impactor. You can use the app to install IPA files on iOS system and also APK files on Android. First, of course, you would need to download IPA or APK apps. I created a short tutorial on how to install IPA using this jailbreak tool. It covers also errors that can happen during the use of Impactor. I used this device management app to install semi-tethered jailbreak tools on iOS. The software works great for that and I can recommend everyone to install and try Cydia Impactor by Saurik. It is important to download the app directly from the developer webpage. Of course, kubadownload offers always direct links.
