How to fix the ‘Couldn’t preview file’ error?

Google Drive is one of the most popular cloud storage solutions at the moment, courtesy of Google’s popularity. However, sheer popularity doesn’t mean that everything goes seamlessly. 

In this article, we’re going over the ‘couldn’t preview file’ error in Google drive and giving you a few solutions to fix the problem.


Check the file format

While Google Drive can preview just about any format, including most images, documents and videos, it doesn’t support every file format floating on the internet. You can go through the list of supported file formats for Google Drive to see if your file is compatible. 

If it isn’t, you’re going to have to convert it to one that is supported by Drive to be able to see a preview.

Enabling all cookies in your browser can also get rid of this problem. Just head over to chrome://settings/cookies and enable the Allow all cookies option. After this, restart your browser and try again.
