Top 3 Ways to Increase Resolution of Images for Better Clarity

December 25, 2023Amanda Brown

Image resolution determines the clarity, sharpness, and overall quality of a captured picture. As the resolution of an image increases, the more details it can capture and display. Low-resolution photos will appear pixelated and blurry when enlarged, while high-resolution ones will remain sharp and clear.

However, not all images are captured with high resolution, and there may arise situations where you need to increase the resolution of an image to enhance its quality or suitability for specific purposes. This post will share three different methods to increase photo resolution on your computers, online and mobile phones.

Part 1. What Is a High-Resolution Photo

A high-resolution photo is a digital image with a large number of pixels, typically exceeding 1,920 x 1,080 pixels. It can be displayed at a large size without losing quality. This enhanced level of detail is particularly crucial for applications where large-scale printing or close-up examination of the image is required.

The resolution of a digital image file is measured in pixels per inch or pixels per centimeter. PPI indicates the number of pixels contained within a single inch of an image, while PPC denotes the number of pixels per centimeter. A higher PPI or PPC value translates to sharper, more detailed images.

Checking the photo resolution is a straightforward process. For instance, you can right-click on the image file, go to Properties, and look for information related to Resolution, Dimensions, or Pixel Dimensions. You can also use some image editors like Adobe Photoshop, GIMP, or Paint to check the resolution of your photo.
