How to Open a ZIP File on iPhone

Search the App Store for “unzip” and you will find dozens of apps, several with subscriptions, all offering to do something your iPhone has done on its own since iOS 13. That is the whole answer to this question, and I want to say it before anything else, because the alternative is you paying for a feature you already own.

I build a free Shortcut for iPhone file work, and it does not handle ZIP files. It does not need to. The Files app does it properly. What follows is the native method, the four places it genuinely falls down, and the far more interesting question of what to do with what comes out.

Opening a ZIP file, the whole method

Apple’s own instructions are three steps and they are correct.

1. Open the Files app and find the ZIP file.
2. Tap the ZIP file. A folder is created next to it containing the contents.
3. Tap the folder to open it.

That is it. No confirmation, no progress bar for small archives, no app. If you want to rename the resulting folder, touch and hold it and choose Rename.

The most common reason this appears not to work is that the ZIP is not in Files yet. If it arrived as an email attachment or in a message, tap it, then use the Share button and choose Save to Files.

Pick a location, then go to Files and tap it there. Tapping an attachment in place often shows a preview of the contents instead of extracting them, which is helpful for a quick look and not the same as unzipping.

Making a ZIP file, since you will want this too

1. Open Files and go to a location you can write to, such as On My iPhone or iCloud Drive.
2. Tap the More button, then tap Select.
3. Tap the files you want.
4. Tap the More button in the lower right, then tap Compress.

Select one file and you get a ZIP with the same name. Select several and you get one called Archive.zip, which you can rename by touching and holding it.

The four things iOS will not do

This is the part the app listings do not tell you, and it is the only reason you might legitimately need something else.

• Password protected ZIPs. The Files app cannot open an encrypted archive and will not prompt you for a password. If someone sent you a protected ZIP, you need either a third party app that supports it or a different way of receiving the files.
• RAR, 7z and the rest. Files handles ZIP. It does not handle RAR or 7z archives. If you are being sent those regularly, the better fix is asking the sender for a ZIP, since that is one setting on their end and an app install on yours.
• Creating a password protected archive. Same gap in the other direction. If you need to send something securely, encryption at the transfer layer, or a link with an expiry, is a better answer than a passworded ZIP anyway.
• Extracting into somewhere you cannot write. Some locations in Files are read only. If nothing happens when you tap, move the archive to On My iPhone first and try again there.

A fifth thing worth watching: space. Unzipping means both the archive and its contents exist on your phone at once, so a four gigabyte archive briefly needs eight gigabytes free. If your phone is nearly full, clear space first or the extraction will fail in a way that does not explain itself.

The iCloud Drive gotcha

If the ZIP is in iCloud Drive and has a small cloud icon next to it, the file is not on your phone yet, only its name is. Tap the cloud icon and wait for it to download before you try to unzip it. On a slow connection this looks exactly like the archive being broken.

Same thing applies to what comes out. Extracting into iCloud Drive means the folder syncs, which is fine and takes time, and takes it silently.

Stop zipping photos and videos to make them smaller

This is the misconception behind a large share of these searches, and it is worth spelling out.

ZIP is a lossless compressor. It finds repetition and encodes it more efficiently. That works brilliantly on text, spreadsheets, code and uncompressed data.

It does close to nothing on JPEG photos, HEIC photos, MP4 videos and most PDFs, because those formats are already compressed. Zipping twenty photos to email them will produce an archive within a percent or two of the size of the twenty photos.

So if your goal is getting under an attachment limit, the ZIP is the wrong tool and you have not actually failed at anything. Compress the media itself.

• A video that will not send. Re-encoding it to a sensible resolution genuinely shrinks it, often by an order of magnitude. See compressing a video for email.
• A very large video. Past a certain size, sending a link beats sending a file. Sending a large video file from an iPhone covers the options.
• A heavy PDF. Scans in particular are mostly images and compress well when treated as such. Reducing a PDF’s file size for email is the method, and compressing a PDF on iPhone goes into the detail.

Where ZIP earns its keep is bundling. Twenty loose files become one attachment, arriving in one piece with the folder structure intact. That is a real benefit and it has nothing to do with size.

What to do with what comes out

Most ZIPs people receive on a phone are one of three things: a data export from a service, a batch of photos from someone, or a set of documents from an institution. Each has a predictable next step.

Photo exports frequently arrive as HEIC, which is efficient and awkward everywhere outside the Apple world. If those photos are going to a Windows machine, a web form or an Android phone, convert them. Converting HEIC to JPG for Windows covers exactly that case and runs on your own device.

Documents from an institution tend to be a pile of loose PDFs and images that would be far easier to deal with as one file. Converting file formats on iPhone covers the general case, including the formats iOS handles locally and the ones it does not.

Grabio is the free Apple Shortcut that puts those conversions in your share sheet, so you can act on an extracted file without leaving Files. No App Store install, no account, no daily cap, and the photo, PDF and audio tools run on your phone with nothing uploaded. Get the Shortcut.

To be completely clear about the division of labour: the unzipping is Apple’s, done natively by the Files app, and Grabio picks up from there. I would rather tell you that than let you install something for a job your phone already does.

Open a ZIP file on iPhone: FAQ

Do I need an app to open a ZIP file on iPhone?

No. The Files app has done this natively since iOS 13. Find the ZIP in Files and tap it, and a folder appears next to it with the contents inside. The App Store apps offering this are charging for a built in feature.

Why does nothing happen when I tap a ZIP file?

Usually because it is not really in Files yet. If it came from Mail or Messages, use the Share button on the attachment and choose Save to Files first. Other causes are a read only location, an iCloud file that has not downloaded, or not enough free storage to hold both the archive and its contents.

Can iPhone open a password protected ZIP?

No. The Files app cannot open encrypted archives and will not ask you for a password. You would need a third party app that supports encrypted ZIPs, or ask the sender to share the files another way.

Can iPhone open RAR or 7z files?

Not natively. Files handles ZIP only. If someone sends you RAR archives regularly, asking them to switch to ZIP is one setting on their end and saves you installing anything.

Will zipping my photos make them small enough to email?

Almost certainly not. Photos and videos are already compressed, so a ZIP of them comes out roughly the same size. Compress the media itself instead. ZIP is for bundling many files into one attachment, which is a different and genuinely useful job.

Where does the unzipped folder go?

Right next to the ZIP file, in the same folder in Files. It takes the archive’s name, and you can rename it by touching and holding the folder and choosing Rename. The original ZIP stays where it was, so delete it once you have what you need.
