How is the resolution affected by resizing?
Twice as many pixels can fit into the same space. If you double the size of an image, the resolution decreases by half, because the pixels are twice as far apart to fit the physical size. For example, a 400 x 400-pixel image, has a physical size of 4 x 4 inches and has a resolution of 100 pixels per inch (ppi).
Why do images lose quality when resized?
By resizing the size of the image, you actually reduce the mega pixel count of the photo. When you reduce the megapixel count, the computer can’t store all the detail any more (there simply aren’t enough pixels to do so). You’ll lose valuable detail in your photos that you’ll never be able to get back.
Why do we resize images?
The reason why you should resize images if you plan to load images to the Internet for display on a web page or for inserting into a presentation is that image file size matters. On the web, the larger the image size the longer it will take the web page to load.

What is used to resize photos?
Resampling is a tool that changes the number of pixels in the image itself. This is the most appropriate tool for resizing images for the web since page speed is so important, especially if you are using original photographs straight from your camera.
Does reducing file size affect resolution?
Many people think that lowering the resolution of an image also lowers the file size of the image, allowing it to download faster over the web. But while it’s true that smaller files sizes download faster, the resolution of your image has nothing to do with its file size.
