To download Avengers: Endgame in the Amazon Prime Video app on an iPhone, open Prime Video, find the movie, open its detail page, and tap Download. When it finishes, the movie appears on the Downloads tab and plays without an Internet connection.
The catch is that you need to have bought or rented the movie from Amazon first. On Amazon’s US store, Endgame is listed as a title to rent or buy, so a Prime membership alone does not put a download button on it. The rest of this guide covers what you need, the full steps, and what to do when the download does not work.
What You Need Before You Start
- The Prime Video app. Amazon only allows offline downloads in its apps (iOS, Android, macOS, Windows 10 and 11, and Fire tablets), not in Safari or another browser. If you do not have it yet, you can get Prime Video from the App Store. The App Store listing currently asks for iOS 17.0 or later.
- The movie in your Amazon account. You must be signed in to the app with the same Amazon account that bought or rented Avengers: Endgame. You do not need a Prime membership to buy, rent, or download a title you paid for. If you are not sure which account you are using, see our guide on how to tell if you have Amazon Prime.
- Free storage. Endgame runs 3 hours and 1 minute, so it is a large file. The exact size depends on the download quality you choose. Check your space first at Settings > General > iPhone Storage.
- A Wi-Fi connection. You can only download while you are online, and a movie this long can use a lot of cellular data.
A current version of the app is assumed here. Amazon has moved and renamed menus over the years (the old Purchases tab is now part of My Stuff), so a label on your screen may sit in a slightly different place than described. If you are not sure the movie is on your account, see how to find your purchased and rented movies in the Prime Video iPhone app.
How to Download Avengers: Endgame in the Prime Video App
One warning before you tap anything. Amazon says an accidental Prime Video order can only be canceled within 14 days if you have not tried to watch or download it. If you bought the wrong version or did not mean to buy the movie at all, sort that out before you download.
- Connect your iPhone to Wi-Fi and open the Prime Video app.
- Sign in with the Amazon account that owns the movie if the app asks you to.
- Find the movie. Either tap Search and type Avengers Endgame, or open My Stuff and choose Purchases & Rentals, which is where Amazon lists everything you have bought or rented.
- Tap the movie to open its detail page. This is the page with the description, the cast, and the play button.
- Tap Download, usually shown with a downward arrow. If the app asks which quality to use, pick one. Higher quality looks sharper and takes more storage.
- Stay connected to Wi-Fi while the progress indicator fills.
- Tap the Downloads tab to see the movie once it has finished. When you are done with it, our guide on removing a Prime Video download or the app from an iPhone shows how to get the space back.

Amazon’s own instructions for this are short: open the app, find the title, and for movies select the option to download from the detail page. You can read them on Amazon’s Download Prime Video Titles help page.
If You Have Not Bought the Movie Yet
Amazon states that selected titles can be rented or purchased through the Amazon website and through the Prime Video app on supported devices. On the movie’s page you will see the available options, such as Rent and Buy, and More purchase options for other video qualities.
If the buy and rent buttons do not appear in your iPhone app, sign in to Amazon in Safari or on a computer, buy the movie there, and then return to the app. The purchase is tied to your account, so it shows up under My Stuff on every device signed in to that account.
Be aware of where the charge goes. According to Amazon, a purchase in the Prime Video app for iOS is charged either to your Amazon 1-Click payment method or to the payment method in your Apple account, depending on how your subscription and payment details are set up. Amazon explains the process on its Rent and Buy Prime Video Titles page.
Bought vs. Rented: The Download Rules Are Different
Whether you bought or rented Endgame changes how the download behaves. These limits come from Amazon’s Prime Video Usage Rules.
| Rule | Purchased movie | Rented movie |
|---|---|---|
| Devices you can download to | Up to four compatible devices | One compatible device |
| How long you can watch | Indefinitely, subject to Amazon’s terms | Typically 48 hours to finish once you start, within a rental window that is typically 30 days |
| Streaming after downloading | Yes | Yes, but not on two devices at the same time |

With a rental, think about which device you will actually watch on before you download. Once a rented video is downloaded to one device, Amazon does not let you download it to another. The exact rental window for a title is shown on its detail page. If you would rather watch on a larger screen, here is how to watch Amazon Prime Video on an iPad.
How to Check That It Worked and Watch Offline
Open the Downloads tab in the Prime Video app. If Avengers: Endgame is listed there with no progress indicator, the download is complete.
To be sure before a flight, turn on Airplane Mode, open Prime Video, go to Downloads, and start the movie. If it plays for a few seconds, you are set. Turn Airplane Mode off again afterward.
One limitation to know about: Amazon does not permit playing downloaded titles over AirPlay or Chromecast. If you plan to watch on a hotel TV, Amazon says offline playback to a television is possible with supported devices and the appropriate adapters.
How to Delete the Download Later
A downloaded movie stays on your iPhone until you remove it. To get the space back, open Downloads in the Prime Video app, open the movie, and choose Delete Download. Amazon describes this option as being on the movie’s own page, next to the button for watching it.
Deleting the download only removes the file from your iPhone. A movie you bought stays in My Stuff and can be streamed or downloaded again. A rental can also be streamed again as long as its viewing period has not run out.
Troubleshooting
There is no Download button
First confirm you are in the Prime Video app and not on the Amazon website, because browsers cannot download. Then confirm the movie is in My Stuff > Purchases & Rentals. If the page only shows rent and buy prices, the app does not see the movie as yours, which usually means you are signed in to a different Amazon account than the one that paid for it.
The download will not start or keeps stopping
- Check your free space. Our guide on checking and freeing up iPhone storage walks through it, and Apple documents the screen in How to check the storage on your iPhone and iPad.
- Check your connection and stay on Wi-Fi. If the app is set to download only on Wi-Fi, a download may wait while you are on cellular data.
- Close the Prime Video app and open it again. Apple’s steps are in Close an app on your iPhone.
- Update Prime Video in the App Store, then restart your iPhone.
- Turn off any VPN. Amazon lists deactivating a VPN or proxy among its fixes for Prime Video problems.
The app says you have reached a download limit
A purchased movie can be downloaded to four devices and a rental to one. If you have already used those, delete the download from a device you no longer need it on, then try again on your iPhone.
The download is too big
Delete the download, choose a lower download quality in the app’s settings, and download again. Our article on changing Prime Video settings on an iPhone shows where the quality options are. If you still need room, see this guide to deleting iPhone apps you no longer use.
Frequently Asked Questions
Is Avengers: Endgame free to download with Amazon Prime?
Not on Amazon’s US store at the time of writing. Amazon lists the movie as available to rent or buy rather than as included with Prime, so you pay for it separately. Catalogs change, so check the movie’s page in the app for the current options.
Do I need a Prime membership to download a movie I bought?
No. Amazon says you do not need an Amazon Prime membership to use Prime Video, and that customers can buy or rent titles without one. You only need an Amazon account and the Prime Video app.
How long does a downloaded copy of Endgame last?
If you bought the movie, Amazon describes the viewing period as indefinite, although it notes that a purchased title can become unavailable because of licensing restrictions. If you rented it, you typically have 48 hours to finish once you start watching, and the rental itself typically expires 30 days after you paid.
Can I download the movie on my iPhone and my iPad?
If you bought it, yes. Amazon allows downloads of a purchased video on up to four compatible devices. If you rented it, you can download it to only one device.
Can I move the downloaded file to a computer or another app?
Amazon does not document any way to do that. Downloads are meant to be watched in the Prime Video app on the device that downloaded them, and Amazon does not permit sending a downloaded title to a TV over AirPlay or Chromecast.
Does the download include bonus features?
That depends on the version you bought. Amazon has sold Endgame both on its own and in a version with bonus features, and they appear as separate titles. Check which one is listed under Purchases & Rentals before you download, because a version with extras is a much larger file.
Next Step
Download the movie the night before you travel, while you are on home Wi-Fi and your iPhone is charging, and run the quick Airplane Mode test so there are no surprises on the plane. If you also subscribe to Disney+, see how to download a movie in Disney+ on an iPhone.
