ZIP files are one of the most convenient ways to compress and share files. But what if you want to keep your files secure? Adding a password to a ZIP file ensures that only people with the password can access its contents. In this guide, we’ll walk you through how to add a password to a ZIP file in Windows 11 using different methods, including built-in features and third-party software.
Why Password-Protect a ZIP File?
Before we dive in, let’s talk about why you might want to do this:
-
Protect sensitive information: Keep personal documents, financial data, or work files safe.
-
Share securely: Ensure that only intended recipients can open the file.
-
Prevent accidental access: Avoid accidental changes or deletions of your files.
Think of password protection as a lock on your digital filing cabinet.

Unfortunately, Windows 11 does not provide a built-in option to add a password to ZIP files. While you can create ZIP files by right-clicking and selecting Send to → Compressed (zipped) folder, you cannot password-protect them without third-party tools.
This means you’ll need software like:
-

WinRAR (trial/free version)

PeaZip (free)
