How to Open a ZIP File

A .zip file is a compressed archive that bundles one or more files together. Every major operating system can open one natively — here's how, plus an online viewer if you just want to look inside.

Category: Archive / compressed file Developer: PKWARE (open format, ISO/IEC 21320) MIME type: application/zip Native support: Windows, macOS, Linux, Android, iOS

Open a ZIP File Online

Drop a .zip file below to browse its contents, preview text and image files, and download whatever you need — without installing anything.

🔒 Nothing is uploaded — your file never leaves this device
Fastest answer: You almost certainly already have what you need. On Windows, right-click the ZIP and choose Extract All. On Mac, just double-click it. On Android and iPhone, tap it in your Files app. No extra software required for a normal ZIP file — and if you just want to peek inside without extracting anything, use the online viewer above.

What is a ZIP file?

ZIP is the most widely used archive format in the world — a single file that bundles and compresses one or more files and folders together, making them smaller to store or transfer and easier to share as one item. It was created by Phil Katz at PKWARE in 1989 and has since become an open, standardized format (ISO/IEC 21320), which is why it's supported natively by essentially every modern operating system without needing extra software.

A ZIP file's structure is simple: each entry (file or folder) is stored with its own compressed data, plus a "central directory" at the end of the archive listing every entry's name, size and location — which is exactly what lets a tool like the one above list the contents instantly without decompressing the whole thing first.

How to open a ZIP file on Windows

  1. Right-click the .zip file in File Explorer.
  2. Choose Extract All… from the menu.
  3. Pick a destination folder, or keep the one Windows suggests.
  4. Click Extract. Windows unpacks everything and opens the destination folder automatically.

You can also just double-click a ZIP to browse its contents like a regular folder, without extracting anything — useful for quickly grabbing a single file. For extra features (stronger compression, splitting archives, other formats), 7-Zip and WinRAR are the most common third-party tools.

How to open a ZIP file on Mac

  1. Double-click the .zip file in Finder.
  2. macOS's built-in Archive Utility extracts it automatically into the same folder.

That's it — no extra software needed for a standard ZIP. For encrypted or unusual archives, The Unarchiver or Keka (both free) handle a wider range of formats and options.

How to open a ZIP file on Linux

Most Linux desktop environments (GNOME, KDE, etc.) let you right-click a .zip file and choose Extract Here directly in the file manager. From a terminal:

unzip archive.zip

If unzip isn't installed, get it with your package manager, e.g. sudo apt install unzip on Debian/Ubuntu.

How to open a ZIP file on Android

  1. Open your Files app (Files by Google, or your manufacturer's file manager).
  2. Tap the .zip file.
  3. Most file managers show an Extract option automatically, or let you browse the contents directly without extracting.

If your file manager doesn't support ZIP, ZArchiver and RAR (which also handles ZIP) are free and widely used alternatives from the Play Store.

How to open a ZIP file on iPhone or iPad

  1. Open the Files app (built into iOS).
  2. Tap the .zip file — iOS extracts it automatically into a new folder with the same name, right next to the original.

No extra app needed for standard ZIP files on modern iOS.

How to create a ZIP file

Windows: select the files, right-click, choose Send to > Compressed (zipped) folder.

Mac: select the files in Finder, right-click, choose Compress.

Linux: select the files in your file manager and choose Compress, or run zip -r archive.zip folder/ from a terminal.

Password-protected ZIP files

ZIP supports built-in password protection and encryption. If you're trying to open one and don't have the password, there's no legitimate shortcut — you need the correct password from whoever created the archive. If you're creating a protected ZIP yourself, 7-Zip and WinRAR both support setting a password with AES-256 encryption, which is considerably stronger than the older, weaker "ZipCrypto" method some tools still default to.

The online viewer on this page can open standard, unencrypted ZIP files, but can't currently open password-protected ones — use a desktop tool with the password for those.

Is it safe to open a ZIP file?

The ZIP format itself is just a container and can't run code on its own. The risk comes from what's inside — a ZIP can contain an executable, a macro-enabled Office document, or a disguised script that causes harm once you extract and open it. Treat files extracted from an unfamiliar ZIP the same way you'd treat any downloaded file: scan them with antivirus software before opening, and be wary of ZIPs from sources you don't recognize.

Common ZIP errors and how to fix them

"The compressed (zipped) folder is invalid" / "Archive is corrupt"

Usually an incomplete download. Re-download the file, ideally checking the file size matches what's expected.

ZIP won't extract, or extracts to empty/garbled files

The file may actually be a different archive format that was renamed to .zip (check with a tool like 7-Zip, which detects the real format regardless of extension), or it may need a password.

"Windows needs a bit more space" or extraction fails partway

Free up disk space — extraction needs room for both the ZIP and the extracted copies simultaneously.

Frequently asked questions

Do I need special software to open a ZIP file?

No. Windows, macOS, most Linux desktops, Android and iOS all have built-in support for opening and extracting ZIP files without installing anything extra. Third-party tools like 7-Zip or WinRAR are only needed for extra features (stronger compression, other archive formats, or repairing damaged archives).

Why won't my ZIP file open or extract?

The most common causes are: the download was interrupted and the file is incomplete or corrupted; the ZIP is password-protected and you don't have the password; the file is actually a different archive format (RAR, 7z) that was simply renamed to .zip; or, rarely, the ZIP uses a compression method your extractor doesn't support.

Can a ZIP file contain a virus?

The ZIP format itself isn't executable, but a ZIP can contain malicious files (an .exe, a macro-enabled document, a disguised script) that cause harm once extracted and opened. Only download ZIP files from sources you trust, and let your antivirus scan extracted contents before opening anything unfamiliar.

How do I open a password-protected ZIP file?

Use an archive tool that supports encrypted ZIPs, such as 7-Zip, WinRAR, or your operating system's built-in extractor, and enter the password when prompted. Without the correct password, there is no legitimate way to open an encrypted ZIP's contents.

What's the difference between ZIP and RAR?

Both are archive formats that compress and bundle files together. ZIP is an open, universally supported format built into every major operating system. RAR is a proprietary format that generally compresses slightly better for large files, but needs third-party software (like WinRAR or 7-Zip) to open on most systems, since it isn't natively supported.
