Top 5 Methods to Increase Image Size in KB or MB

You may easily receive or download compressed pictures that contain a small file size. The small file size often comes with a big problem, the low quality. To upscale your image to a higher resolution and enhance quality, you may want to increase image size in KB or MB. In some cases, you need to change image size to meet the specific requirement for uploading or sharing. This article shares five helpful ways to easily increase the MB or KB size of your photo.

Part 1. What Are KB, MB, and the Main Difference

Before telling you specific methods to increase image size in KB or MB, I would like to explain what KB and MB are and the relationship between image size and quality.

Image files essentially collect a large number of data points to represent colors and details. KB and MB are units used to measure data storage capacity. One KB (Kilobyte) is equal to 1,024 bytes, and one MB (Megabyte) is equal to 1,024 KB. A byte can stand for a single character, such as a number, symbol, or letter. It is the fundamental unit of digital information. So, the more bytes an image contains, the larger the file size and the higher the quality. Surely, besides the number of bytes, compression techniques can also affect the final file size and image quality.
