Especially in corporate organizations, email filters tend to block large attachments for security’s sake. But if you want to include some images to ensure your looks great, what do you do? Worse, in plenty of in the market, few actually teach you different ways to compress your PowerPoint files before sending as an attachment via email or only cover it on Windows or OSX. Fear not, here are some ways in which you can reduce the size and save space. Compressing PowerPoint files on Apple OSX If you own a Mac but still need to use PowerPoint for work, you’re in luck.

Method 2 Compress PowerPoint pictures You can make the PowerPoint file size smaller by reducing the color format of the pictures (compressing).

There are a few ways of compressing PowerPoint files to fit your file limit in organizations with email filters so you won’t need to use file-sharing services like DropBox or Wetransfer. Method One – Compressing All photos on PowerPoint More often than not, PowerPoint balloons in size because of high-resolution stock photography that you might include in your presentation. Thankfully, there’s an easy way to quickly compress these files across the whole file.

On the file menu, click “reduce compress pictures” 2. Select your compression size according to the table Unless you’re intending to print the PowerPoint file, you shouldn’t have photos sized at 220ppi. We’ve found that the best setting in most cases is 150ppi – such that it preserves minimal quality for use. If you’re really in the need of smaller sizes, using 96ppi is your last resort. 3.Select “delete cropped area” 4. Choose “all pictures in this file” 5.

Select Compress Pictures 4. Select your compression size according to the table 5. Select “delete cropped area” 6. Choose “all pictures in this file” 7. Click “Ok” Alternatively, if you wish to be selective about the photos being compressed, PowerPoint provides another option to compress only specific images. Under steps 4 and 6 respectively, you will be able to choose between the option of all pictures or just a selective few.

However, if you wish to retain the size of the slides and still send it to people, you can consider zipping the file. Most of the time, people choose this option in order to keep the resolution at its highest without compromising it. Method Three – Compressing Before Inserting Images There will always be a limitation of how small image sizes can be using the inbuilt compression application in PowerPoint. One of the most foolproof ways to ensure file sizes are optimised is to optimise the images even before you insert them into PowerPoint. Here’s how: 1. Reduce the size of images losslessly using browser-based applications Tools like and are great to reduce the size of your files without installing any additional applications on your machine. Optimize the dimensions of your presentation images before inserting into PowerPoint This step is most commonly overlooked by most executives simply because it’s pretty tedious.

It involves ‘pre-cropping’ the images you plan to insert into your presentation even before you try any of the methods before this. A) The first step is to determine the max dimensions of your slide. You can do this by accessing the ‘slide size’ in the ‘design’ tab. B) Enter ‘Page Setup’ when navigating into ‘Slide Size’ to identify the dimensions of each slide. If you’re using any of the typical slide dimensions like Standard (4:3) or Widescreen (16:9), typically the safe dimension is 1024px x 768px and 1280px 720px respectively.

C) The very next step is to start cropping the images to fit within the slide dimensions. For example, if your image is 3000px x 2000px, cropping it down to size will save you a lot of space. Using sites like, you can quickly resize images to fit your slide canvas. At the same time, if you’re using raster editing programs like Adobe Photoshop, you can easily reduce the dimensions of your images before saving. Otherwise, site-based tools work too. Method Four – Zipping Files This method is best performed at the end and works regardless of whether you actually compressed the images prior or not. Right-click on selected PowerPoint file 2.
