What’s the difference between high and low resolution graphics/images?

Before this question can be answered, it’s important to explain how resolution is measured in the world of graphic design. Even if you’re not that familiar with resolution, you probably have some idea that it has to do with a graphic’s clarity and sharpness. Basically, resolution is associated with the ink dots that make up your image, also referred to as electronic pixels. In graphic design, these pixels are called DPI (dots per inch). Other measures of resolution include PPI (pixels per inch), LPI (lines per inch) and SPI (samples per inch).

Can I Change a Low Resolution Image to High Resolution?

High resolution is 300 dpi (dots per inch), whereas low resolution pictures are less than 300 dpi. Images that are in high resolution provide a clearer picture, due to the concentrated and tight combination of dots per inch. Conversely, you’ll notice more dots on a low resolution image and the picture won’t be as precise. In graphic design, low resolution images are going to look pixelated, blurry and not as clear-cut as high resolution images. High resolution images are needed for print design in order to produce crisp, clear images. Lower resolution images can be used for web. No, you cannot change a low resolution to be high resolution in graphic design. There is no way to add pixels to a low resolution image.
