There are many options available that will allow you to convert PDF to PowerPoint files. Which method is most suited to your task will depend on many factors such as budget, features, how often you will need to perform the task, and if you will want to be able to access the functionality from just one, or from many computers. Luckily there are options suitable for just about any mix of the aforementioned factors, so you can afford to be picky.

One of the most common and easiest methods is to use an online converter to convert your PDF to PowerPoint file types. This option allows you to access the desired functionality from any computer that is connected to the internet and has a compatible browser installed. This way is great for when you are on the road or away from your workstation. The downside here is that online converters often have very limited functionality. This will vary from site to site, so choose carefully. You may still be able to find a site which offers the functionality you need, although sometimes you will have to pay for the extended functionality. (In such cases a trial version is often available, which if you only need to do a few conversions will allow you to still do so essentially for free.)

Another method that is available on almost any computer is to simply use the print screen functionality of your operating system or screen capture utility to copy the PDF file and then paste it into PowerPoint. This can be a bit tricky to get right though, as PDF files allow the user to scale the visual representation of the file, but once you take a screenshot or screencapture of your PDF file the resulting image in your clipboard or wherever you paste it will not scale the same. This is because when a PDF is scaled in a PDF viewer, the resolution increases as the scale increases, and the resolution is reduced when the zoom is decreased. On the other hand, an image file (a screencapture being a bitmap image of what is viewable on the screen at the time) can be zoomed in and out, but the resolution stays the same regardless of the zoom level. So when using this method to convert PDF to Powerpoint, make sure to zoom to the level you wish to use in your PowerPoint slide, otherwise there could be pixelation or a loss of readability.

Of course you can always use Microsoft PowerPoint's built in option to import from PDF. This is a quick and easy way to convert PDF to PowerPoint file types, but has some missing functionality that some users may need. Also it means you need to own Microsoft PowerPoint, which is part of the Microsoft Office Suite, and can be a very expensive option if you don't already own or have access to it. There are inexpensive versions of Microsoft Office suite that you can purchase if you qualify, such as the student edition. If you need a more powerful solution, there are commercial software applications available that offer a full range of functionality, and generally cost much less than a full office suite.
