iPhone doesn't have a built-in app that opens zip files the way your computer does, but you can unzip them directly in Files or use a free app
When you receive a zip file on your iPhone — usually as an email attachment or download — your phone doesn't automatically unzip it like a Windows or Mac computer would. Instead, you have three working routes: use the Files app (which comes on every iPhone), use Mail's built-in unzip feature if the file arrived by email, or download a free unzip app from the App Store. The fastest route depends on where the zip file is right now.
The Files app works for any zip file already on your phone. Mail can unzip attachments directly without leaving the email. A dedicated app like Archive Utility or iZip gives you more control if you work with zips regularly. All three methods produce the same result — a folder containing the original files — and take less than a minute.
Key Takeaways
- The Files app, which comes pre-installed on every iPhone, can unzip files without downloading anything extra.
- If a zip file arrived as an email attachment, Mail can unzip it directly — just tap and hold the attachment, then select "Save to Files".
- Free unzip apps like Archive Utility or iZip are available from the App Store if you prefer a dedicated tool.
- After unzipping, the original files appear in a folder you can move, copy, or open with other apps.
- The unzipped folder stays on your phone until you delete it — the original zip file does not automatically disappear.
Unzip a file using the Files app
Open the Files app on your home screen (it looks like a blue folder). Navigate to the location where your zip file is stored — usually iCloud Drive, On My iPhone, or Downloads. Tap and hold the zip file until a menu appears.
Select "Uncompress" from the menu. The Files app will unzip the file in the same location, creating a folder with the same name. This takes a few seconds for small files and longer for large ones. Once finished, you will see both the original zip file and the new uncompressed folder side by side.
Open the folder to see what was inside the zip. You can now move these files to other locations, open them with compatible apps, or share them. The original zip file remains on your phone unless you delete it manually.
Unzip an email attachment directly in Mail
If someone sent you a zip file as an email attachment, you do not need to save it first. Open the email and look for the attachment — it appears as a file icon below the message text. Tap and hold the attachment until a menu appears.
Select "Save to Files" from the menu. A window opens asking where you want to save it. Choose a location like iCloud Drive or On My iPhone, then tap "Save". Mail automatically unzips the file as it saves, so you end up with the uncompressed folder, not the zip itself.
Once saved, you can open the Files app and navigate to that location to see the unzipped contents. This method is fastest if you only need the files inside and do not need to keep the zip file itself.
Download a free unzip app from the App Store
If you work with zip files regularly or want more features, download a free app like Archive Utility, iZip, or Zip Master from the App Store. Open the App Store, tap the Search tab at the bottom, and search for "unzip" or "zip". Choose an app with good reviews and tap "Get" to download it.
Once installed, open the app and navigate to your zip file. Most unzip apps let you browse files inside a zip before uncompressing, preview documents, and organize unzipped files into folders. Some also let you create new zip files from existing folders, which the Files app cannot do.
These apps work the same way as the Files app for basic unzipping but offer more control over where files go and what you do with them afterward. They are useful if you regularly receive zip files for work or hobbies.
What happens after you unzip a file
After unzipping, you have a folder containing the original files. The folder behaves like any other folder on your iPhone — you can open it, move it to a different location, or share it with other people. The files inside can be opened by any compatible app on your phone.
The original zip file does not automatically delete. If you no longer need it, you can delete it manually by tapping and holding it in Files and selecting "Delete". Deleting the zip file does not affect the unzipped folder or its contents — they remain on your phone.
If the unzipped folder contains many large files, it may take up significant storage space. You can check how much space it uses by tapping and holding the folder and selecting "Info". If you need to free up space, delete the unzipped folder (but keep the zip file if you might need those files again).
Troubleshooting when unzip does not work
If tapping and holding the zip file does not show an "Uncompress" option, the file may be corrupted or incomplete. Try downloading it again from the source. If it arrived by email, ask the sender to resend it.
If the Files app shows the zip file but will not unzip it, try using a dedicated app instead. Sometimes a zip file created on Windows or with specific compression settings works better with a third-party unzip app than with Files.
If you see the zip file in Mail but cannot save it, make sure you have enough storage space on your iPhone. Go to Settings > General > iPhone Storage to check. If storage is nearly full, delete large files or apps you no longer need, then try again.
Moving unzipped files to other apps
After unzipping, you can open the files with other apps on your phone. For example, if the zip contained photos, you can move them to Photos. If it contained documents, you can open them in Word, Google Docs, or another document app.
To move a file, open Files, find the unzipped file, tap and hold it, and select "Move". Choose the destination — for photos, this might be the Photos app; for documents, it might be iCloud Drive or another cloud storage app. Some apps also let you open files directly from Files without moving them first.
If you want to share the unzipped files with someone else, tap and hold the folder in Files and select "Share". You can send it via email, AirDrop, or any other sharing method your phone supports. The recipient will receive the unzipped folder, not the zip file.
Frequently Asked Questions
Can I unzip a file that is still downloading?
No. Wait for the download to finish completely before trying to unzip. If you try to unzip while it is still downloading, the Files app will show an error or the unzip will fail partway through. Check the Downloads folder to confirm the file shows a complete checkmark before unzipping.
What if the zip file contains a folder inside a folder?
The folder structure stays the same after unzipping. If the zip contained Folder A inside Folder B, unzipping creates Folder B with Folder A inside it. You can navigate through the folders in Files the same way you would on a computer.
Does unzipping use up more storage space?
Yes. The unzipped files take up the same amount of space as they did before being zipped, sometimes slightly more. If you are low on storage, you may need to delete the zip file after unzipping to free up space, since you now have both the zip and the uncompressed version.
Can I unzip a file that is in iCloud Drive but not downloaded to my phone yet?
You need to download it first. In Files, tap and hold the zip file in iCloud Drive and select "Download". Once it finishes downloading, then use the Uncompress option. Files will not unzip files that are only stored in the cloud.
What if I unzip a file and it creates a folder with a strange name?
The folder name comes from the original zip file name. If the zip was named something like "Archive.zip", the folder will be named "Archive". You can rename it by tapping and holding the folder, selecting "Rename", and typing a new name.
