The more pixels, the higher the resolution. Simply put, resolution is the relationship between the dimensions of an image and the number of pixels contained within those dimensions. However, newer computers and mobile devices have the ability to display more pixels in a smaller physical space, resulting in a crisp, smooth appearance. On older computer monitors, these pixels were more easily visible because they were less dense. “Pixel” is a portmanteau of “picture” and “element.” You can think of pixels as tiny building blocks of graphic information.Įverything you see on a screen is comprised of pixels. Pixels are the standard unit of measurement for screens.
Let’s start with some common questions and vocabulary pertaining to image resolution. Selecting a region changes the language and/or content on, we’re learning all about the lingo of image resizing, how to quickly determine image resolution, how to convert from inches to pixels, centimeters to pixels (and vice versa), and how to resize your image using Adobe Photoshop or Shutterstock Create, all while retaining quality. So, when you need to decide between compressing an image and resizing it, think ahead to what you may need that image for in the future - and always keep a copy of your original picture, just in case. This comes in handy when you need to store your down blanket away for the summer, but you might regret it when winter comes around. The aspect ratio - that is, the dimensions of length and width - will be different than before. With image resizing, think of it as tailoring your blanket from a king size to a twin size. In both cases, you still have the same basic blanket, but one will be slightly fluffier than the other. Or, if you need to make the blanket even smaller, you could remove some of the feathers before packing it up. Think of it like a fluffy down blanket - you can reduce its size by packing it into a box. However, there are critical differences between the two techniques that you should know if you want to set up your image files for success.Īs you learned above, image compression reduces the amount of visual information in a file. Compression and resizing are similar concepts - both can make your file sizes smaller.
