👓 Understand PPI, DPI, and Resolution

Before we dive into the real methods and tools for enlarging pictures, it’s vital to understand the factors of image resolution. Well, resolution usually refers to the number of pixels that make up an image. It is typically represented by the width and height in pixels like 1920×1080. As you should know, image quality is directly related to resolution, which means that the more pixels in an image, the better the detail and quality.

dpi and ppi

  • Pixels per inch (PPI) refers to the measure of resolution on the computer screen, TV screen, or any other on-screen display device. It is a term that is often used in web pages, the photography industry, cameras, and digital images. The more pixels in an image, the higher the resolution and the larger the picture size.
  • Dots per inch (DPI) is typically used to refer to the number of dots that can be placed in a line within one inch. It is widely used in the printing industry to describe printed documents. In general, the higher the dots’ intensity, the higher the resolution, and the better quality of the prints. That is why although many images digital devices show are in 72 DPI, they will not make pictures blurry when we see them on computer or phone screens.

When you enlarge a picture, you’re essentially stretching these pixels, which can result in pixelation and loss of quality. Adding more pixels is the key to blowing up an image without losing quality. Now that you know what really affects the image quality, let’s explore the best methods for enlarging pictures without losing quality.
