Plenty of users describe that they are in the unfortunate position of wanting to open a ZIP file, just to discover that it has been corrupted after download.

It gets even more frustrating since the same ZIP seems to open correctly for others. That’s a sign that the issue may not be with the original file.

The corruption could happen during the download or even at a later point, in the storage. Therefore, it’s most likely related to your file archiver, the antivirus that you use, and not only.

Just take a look at our comprehensive tips below and solve the issue right away.

How to fix corrupted ZIP files after download?

1. Try out WinZip

Imagine yourself facing the same situation of downloading large ZIP files, trying to unzip them, and eventually getting the same corruption notification over and over again.

To prevent that from happening, make sure that you use a reliable file archiver, such as the one developed by WinZip Computing.

WinZip can easily finish downloading and unzip all major file formats, including zip, rar, gzip tar, and cab, while your private data can be password-protected and encrypted with 256-bit AES encryption.

Other useful options are maximum flexibility to zip files and folders, easy management of files on your system, cloud, and network, along with decoding capabilities for B64, HQX, and UUE files.

3. Check your antivirus

try out Bitdefender

Computer malware, Trojans, and worms can easily damage your personal computer, steal your private data, and not only, so using an antivirus tool is mandatory.

However, if your antivirus of choice slowly checks the files you’re downloading bit by bit, it could delay the entire process and cause ZIP file corrupted issues.

Temporarily turn if off to confirm this scenario and later on, think of a different option. Today’s Internet provides a variety of open gates for virus attacks, yet Bitdefender closes them all.

This is possible thanks to an unbeatable daily updates mechanism of antivirus database definitions, not to mention that it’s speedy and never interferes with your system.

This happens all the time when using other tools, so the change most likely sounds like music to your ears.

Another common reason for these issues is precisely the lack of stable Internet speed for the download itself.

Fortunately, you can use one of these great Internet speed testers for Windows 10 for a precise answer that could nail down the culprits’ list.

If you do confirm an unstable Internet connection issue, this clearly turns into a problem for downloading ZIP files. Also, don’t hesitate to make sure that your cable is not damaged.

6. Redownload the ZIP from the FTP server via FTP

If the ZIP file corrupted after the download issue is still there, perhaps you need to try downloading it from the FTP server via FTP rather than HTTP.

As you can see, that’s a standard network protocol dedicated to transferring files from one host to another host over a TCP-based network, so do give it a go.

There are some of the most useful solutions that we recommend for everyone to try when ZIP files get corrupted after download.
