How to Increase Image Resolution in a Cost-Effective Way?

What is image resolution

Image resolution is a description of the detail that the image holds. Image resolution is described using pixel per inch (PPI), which means the number of pixels displayed per inch of a particular image. Higher resolutions imply more PPI, resulting in higher pixel information and giving you a crisp and high-quality image.

On the other hand, images with lower resolutions have fewer pixels, and in case those pixels are large – mostly when the image is stretched, the image tends to become blurred.

High resolution vs. low resolution

Higher resolution gives a sharper, crisp, clear, and high-quality image, whereas, for low resolution, the image or picture you get is blurred and stretchy.

When high-resolution images are used for web graphics, their load time is high, unlike low-resolution images that look fabulous on computer screens. A high-resolution image has more pixels per inch than a low-resolution image with fewer pixels per inch.

Other Image Upscaling FAQs

  1. Why Upscale a Small Image?

Upscaling a small image involves adding more pixels to a small image to improve its resolution. This process implies that there will be only the same as many pixels per inch. If you alter the image resolution, the physical size is also changed. Important to note that pixel sizing controls the data amount, and physical size and resolution are only usable for printing. Also, upscaling improves the quality of the image, including its clarity, crispiness, sharpness to the physical eye. In other words, upscaling stretches the image to suit the resolution you display. For instance, a 720p is being upscaled to fit a screen of 1080p.
