There are numerous reasons you would want to convert a PowerPoint presentation to the Keynote format. Perhaps you intend to send a PPTX or PPT file to a recipient with a Mac. Or maybe you received or downloaded a presentation as a PowerPoint file to your Mac.

Thankfully, converting a PowerPoint presentation from the PPTX or PPT format to the KEY format is quite easy. Perhaps even easier than you think. So without any further ado, let’s go through three easy ways to help you do that.

1. Use ZamZar

On Windows, the most convenient way to convert a PowerPoint presentation to the Keynote format is to use an online file conversion service. ZamZar was our pick for a couple of reasons; the service has been around for almost 15 years, and there were no other reputable file converters that could perform PPTX to KEY conversions.

Step 1: Open ZamZar in your preferred web browser. Then, click the Add Files button and upload the PPTX or PPT file that you want to convert. The file should not exceed 50MB in file size.

Note: ZamZar lets you convert up to two PPTX files within a 24 hour time period. If you want to convert more than that, you must subscribe to a paid plan.

Step 2: Set the output format to KEY, and then click Convert.

However, you must keep a couple of issues in mind while using a file conversion service such as ZamZar. Firstly, you must be aware of privacy implications. If the presentation contains sensitive information, it’s best to avoid this method since there are no guarantees of where your data might end up in.

Secondly, there are formatting issues to consider. Converted KEY files may not carry the same formatting (fonts, for example) as their original PPTX/PPT files. The problem is further compounded by the fact that PowerPoint (which you probably used to generate the presentation) doesn’t support KEY files, so there’s no way to check either.

The next method is not only private and secure, but it also allows you to convert as many files as you want.

2. Use iCloud Keynote

The online version of iCloud Keynote also features the ability to convert PPTX files to the KEY format. If you don’t have access to an iCloud account, you can create one for free here. You do not need to have an iPhone, an iPad, or a Mac for that, although you only get one gigabyte of free storage instead of 5GB.

Step 1: After signing into iCloud.com, select Keynote from the iCloud Launchpad.

3. Convert Using Keynote

If you use Keynote on your Mac, iPhone, or iPad, you can open any PPTX or PPT file quite easily since the application features native support for both formats. Converting them to the KEY format is then as simple as saving them.


Step 1: Double-click the PPTX or PPT file. Keynote will then process the file briefly and open it automatically.
