Often, file sizes are simply too large and clunky for your intended purpose or use. Do you need to compress a PowerPoint file to make it easier to save or share? WinZip can make it easier.

What are .ppt Files?

PowerPoint files, also known as .ppt files, are presentation files. They are often clunky files that contain a great deal of data, including images and text. PowerPoint files frequently have effects, videos, and multiple slides, all of which can combine to create a very large file size.

Why to Compress PowerPoint Files

Because of their large size, PowerPoint files can have some difficulty. Consider these reasons to compress .ppt files.

1. You want to be able to send a .ppt file via email.

Whether you're collaborating on a presentation with a partner and need to send the file back and forth, or you're trying to send a file to a new location, it can be difficult to share a large .ppt file. Your file transfer may bog down, making it difficult to both send and download the file. Compressing the file, on the other hand, can streamline the transfer process and make it easier for both parties. compress can also make it easier to transfer your file to online storage.

3. You're planning to save a .ppt file or several .ppt files.

File storage space is not unlimited. While many virtual storage options now allow you to save and store a considerable amount of data, many users quickly run out of free storage and need to pay for storage for their additional files. By compressing your file, you can fit it into a smaller virtual "space," which means that you can store more files and won't have to pay as much for your storage solutions. Compressed files are also easier to transfer and back up, which means that you'll be more likely to complete those essential data backups on time.

How to Compress PowerPoint Files

When it comes to compressing PowerPoint files, you have two basic choices:

  • Compressing images in the PowerPoint File, and
  • Compressing the entire file

Compressing images is a great way to reduce your overall file size. It is, however, a time-consuming process. You'll need to go in, click on each image in the PowerPoint presentation, and open the PowerPoint picture tools. Then, select "Compress Pictures" on the left of the toolbar.

Your second option is to compress the entire .ppt file with WinZip. WinZip can compress either individual images within your presentation or compress the whole file for smaller storage and sending. WinZip is compatible with most file storage and transfer methods, including DropBox and Google Drive, and will make it easy for you to shrink the overall size of your file.
