How to Change Pixel Size of Image on Mac

When it comes to measuring screen resolution, many people focus on the number of pixels across and high, such as 1920 x 1080 for a standard HD monitor. However, a better way to measure is by looking at the overall pixel density, which is measured in pixels per inch (PPI). For example, some screens have a native resolution of 326 PPI, while others may be as high as 750 x 1334 pixels.

The quality of your final images can make all the difference between a professional-looking result and an amateurish one. To achieve the best possible image quality, it's essential to keep the pixel density close to the original size. This article will show you how to do just that by finding the perfect resolution for your needs.

Too much resolution won't necessarily affect the display quality of your images, but it can result in unnecessarily large file sizes. On the other hand, if there isn't enough resolution, your image may appear soft or pixelated, with visible jaggies and a loss of detail. To achieve more density and therefore more resolution, you need to increase the number of pixels.

The terms 'hi-res' and 'low-res' refer to high- and low-resolution images, while DPI (dots per inch) and PPI (pixels per inch) are both used to describe resolution. However, it's important to note that DPI is typically used for print materials, not digital displays. In an oversimplification, you can think of DPI as referring to the density of ink dots on a printed page, while PPI refers to the density of pixels on a digital screen.

To get the best results when resizing your images, follow these simple steps:

1. Choose your new size, selecting different measurement units by clicking on 'inches' if needed.

2. Turn off the chain link so that you can set your own width and height.

3. Grab an image to test for yourself, which contains a variety of elements such as fine lines, thicker text, fine curved lines, gradients, and an image.

In this article, we'll explore how to resize images in Photoshop using the best settings for resizing, enlargements, and reductions of image sizes. By following these tips, you can achieve professional-looking results that will enhance your digital images.
