How to Increase Resolution in Photoshop

The quality of images on your website or a marketing post is one of the things that your visitors will notice immediately. Poor image quality can potentially put your visitors off, and you may even lose some considerable traffic.

One of the most important factors that determine the quality of an image is its resolution. The resolution of an image is the number of pixels per inch (PPI) in an image. The higher the resolution, the more pixels there are per inch and the image will be sharper. However, increasing the resolution also increases the file size.

Today’s internet users notice the quality of your images first and foremost. Because of the reasons, you will definitely need to know How to increase resolution in Photoshop. You can change canvas size with Photoshop without a loss of image quality.

4. Set the resample dropdown to Automatic. Notice that the Pixel Dimensions — width, height and file size — at the top of the dialog box increase, whereas the width and height in the Document Size section remain unchanged. For example, an 8-bit RGB image that measures 500 pixels wide by 618 pixels high at 100 PPI remains 5 inches wide by 6.18 inches high at 300 PPI but becomes 1500 pixels wide by 1854 pixel high, and increases in file size from 905.3K to 7.96MB.

5. Click on the “OK” to apply your settings.

6. Look at your image window and image quality. Because you increased the resolution of your image, and by that its file size, your image window appears larger. With that increased size, however, comes pixelation introduced when Photoshop interpolated new pixels to accommodate the larger file area.
