PowerPoint compress images tool is a great feature of Microsoft Office.

Let’s understand first…
What is image compression?
Image compression is nothing more but reducing the size of an image. Sometimes also referred as image optimisation in SEO terms. There are two main types of image compression, lossless and lossy. There are tons of image compression tools available online.
Lossless means you are not willing to sacrifice the quality of the image. This option is generally suitable for offline presentations, where there is no server load.
The time it takes to load or view a image offline depends on your computer configuration itself. Luckily, in 21st century most of us have the privilege of using computers with decent configuration. Therefore, when you are showing a image as project, presentation or recapping old memories it appears in blink of an eye.

Lossy means you are willing to compromise the quality of picture. Usually that occurs for one of the three following reasons:
- You are using the image for a website and want it to load quicker
- Your website has basic shared hosting plan and does not have high end resources to load the contents quicker.
- You are not able to or don’t know how to use the resources i.e. cache, lazy load, cloudflare, and not familiar with image compression.
Having the images load quicker along with other objects for your website means engaged visitors.
Imagine if a website is loading very slow or taking forever, you would not stick around, would you?
As a newbie to online business, blog or website:
- You want to save money
- Test a few things before buying big web hosting plans
- Avoid complicated stuff like installing cache plugins or cloudflare
