How to Encrypt Zip Files Before Emailing Them

If you need to share a large volume of documents with a recipient by email, zipping them beforehand is a great way to reduce the overall package size. Zipping files not only compresses the information but also reduces upload and download times because you’re sending one single zip file rather than multiple individual files.

One thing to keep in mind though is that if you’re sharing confidential information, you’ll need to encrypt the zip file before sending it via email. Email on its own does not protect your information whatsoever. While your information is being transferred, there is a potential for it to be intercepted by unauthorized parties.

Encrypting zip files is really simple if you’re using third-party software like TitanFile or WinRar.

2. How to encrypt zip files with WinRar

To encrypt a zip file, you’ll need file compression software such as WinRar. You can download the latest copy of WinRar here. The free version is all you need.

Once you have WinRar installed on your computer, follow these simple steps to encrypt zipped files:

1. Locate the file or folder you wish to zip, then right-click it and select Add to archive.

2. Click Set Password.

3. Set the password you wish to use. This password will need to be provided to the recipient later. It’s best to use a password that’s at least 12 characters long because it would take centuries for someone to crack. Then, click OK.

4. Now, select ZIP in the “Archive format” section and then click OK.

5. Once the compression process is complete, you’ll see the zipped file in the same directory.

And voila! You just successfully encrypted a zip file.

You can now send this file securely via email, without having to worry about access from unauthorized parties!
