Before you proceed, you must understand the risks involved in sideloading IPAs:
An IPA (iOS App Store Package) is the archive file for an iOS app. When you search for “Facebook IPA for iOS 1255,” you are looking for a specific version of the Facebook app that was signed to run on that specific firmware.
The search for “facebook ipa for ios 1255” most likely stems from a misunderstanding of Apple’s versioning system (12.5.5 vs 1255). For users on legitimate legacy iOS 12 devices, simply use the App Store’s “last compatible version” feature. For everyone else, remember: if a website offers an IPA for an iOS version that doesn’t exist, they aren’t offering software—they’re offering malware.
Keep your data safe, and consider upgrading to a device that supports iOS 15 or higher if you need modern Facebook features.

The search for a Facebook IPA for iOS 12.5.5 typically involves users trying to run the app on older Apple devices—like the iPhone 5s, iPhone 6, or iPad Air—that cannot update past iOS 12. Because the official Facebook App Store page now requires iOS 15.1 or later, the standard "Get" button may not work for a fresh install. How to Install Facebook on iOS 12.5.5
If you are looking for an IPA (application package) to sideload, there are safer ways to get the app working without downloading potentially malicious files from third-party sites:
Download from "Purchased" History: If you have previously downloaded Facebook on any Apple device using your current Apple ID, go to the App Store > Profile Icon > Purchased. Find Facebook and tap the cloud icon. iOS will often offer to download the "last compatible version" for your device.
Use a Newer Device First: If you have never "owned" the app on your account, log into your Apple ID on a friend's newer iPhone (iOS 15+), download Facebook, then delete it. It will now appear in your "Purchased" history on your iOS 12.5.5 device, allowing you to download the older version. facebook ipa for ios 1255
The Web Alternative: If the app is too slow or refuses to install, using the mobile website via Safari is the most secure method. You can tap the "Share" button and select "Add to Home Screen" to create a shortcut that looks like an app icon. Why Older Versions Are Hard to Find
Security Risks: Downloading IPAs from unofficial "archive" sites is risky. These files can be modified to include malware or steal your login credentials.
API Deprecation: Even if you successfully sideload an old IPA, Facebook frequently updates its servers. Older app versions often lose the ability to load feeds, send messages, or log in entirely.
End of Support: Facebook officially discontinued lightweight alternatives like Facebook Lite for iOS years ago, leaving the standard app (or the web browser) as the only options.

Facebook IPA for iOS 12.5.5 The search for a Facebook IPA for iOS 12.5.5 typically stems from users owning older hardware, such as the iPhone 6, iPhone 5s, or original iPad Air. These devices cannot update to iOS 13 or later, which often prevents them from downloading the latest version of the Facebook app directly from the App Store. Since Facebook frequently updates its minimum system requirements, finding a compatible IPA file becomes necessary to keep these legacy devices functional.
The primary challenge with iOS 12.5.5 is that the official App Store version of Facebook often requires iOS 13.4 or higher. While the App Store sometimes offers a "Last Compatible Version" if you have previously downloaded the app, this feature is not always reliable. Consequently, users turn to IPA files—the iOS equivalent of an Android APK—to manually sideload the application onto their devices.
To successfully install Facebook on iOS 12.5.5, you must locate a version of the app released roughly between 2020 and 2021. Versions in the 250 to 300 range are generally the most stable for this specific firmware. However, downloading IPA files from third-party repositories carries significant security risks. These files can be modified to include malware or credential-stealing scripts. It is essential to use reputable community archives and always verify the integrity of the file before installation.
The installation process for an IPA on iOS 12.5.5 usually requires a computer and a sideloading utility. Sideloadly and AltStore are the most popular choices for this task. These tools allow you to sign the IPA with your Apple ID and install it over a USB connection. Users should be aware that apps installed via a free developer account expire every seven days, requiring a quick re-installation to remain active. Alternatively, jailbroken devices can use tools like AppSync Unified to install IPAs without the seven-day restriction.
Once installed, performance on iOS 12.5.5 may vary. Because the hardware in these older devices is limited, the app might experience slow loading times or occasional crashes. To improve the experience, some users prefer the Facebook Lite IPA, which uses fewer system resources and is often more compatible with older processors. If the app refuses to log in due to "outdated version" errors, users sometimes have to use a mobile browser like Safari as a more reliable, albeit less integrated, alternative.
The current version of the Facebook app is no longer officially supported on devices running iOS 12.5.5 (such as the iPhone 6, 6 Plus, or 5s). As of 2026, the official Facebook App Store listing requires iOS 15.1 or later. Installation Status & Solutions

Facebook IPA for iOS 12.5.5: How to Install on Older iPhones
If you are using an older device like the iPhone 5s, iPhone 6, or iPhone 6 Plus, you have likely encountered a frustrating message: "This application requires iOS 13.4 or later". Because these devices are capped at iOS 12.5.5 (or the slightly newer security updates like 12.5.7), the standard App Store version of Facebook is no longer compatible.
However, there are still several ways to access Facebook on your legacy device without needing a newer phone. 1. The "Purchased" Method (Recommended)
This is the safest and most reliable way to get a compatible version of Facebook without searching for sketchy IPA files online.
Requirements: You must have "purchased" (downloaded) Facebook on your Apple ID at some point in the past. Step-by-Step: Open the App Store on your iPhone 6 or 5s. Tap your Profile Icon in the top right corner. Go to Purchased (or "My Purchases"). Search for "Facebook" in the list. Tap the Cloud Download icon.
When the prompt appears saying the current version isn't compatible, tap Download to install the "last compatible version" for your device.
Pro Tip: If you’ve never downloaded Facebook before, sign in with your Apple ID on a friend's newer iPhone (iOS 14+) and download Facebook there first. Once it’s in your "Purchased" history, it will appear on your older device for download. 2. Using IPA Files via Sideloading
If the App Store method fails, some users look for Facebook IPA files to sideload. An IPA is the installation package for iOS apps.
