The image resolution of a digital image is the number of pixels it holds and is typically expressed as DPI (Dots Per Inch). The higher the DPI, the better the image quality, especially on printed copies. However, when you're sending such images via email or displaying them on a website, you want to reduce resolution, which reduces the files size and loads the image more quickly.
Instructions
1. Download, install and run an image resolution utility such as the free Picture Resize Genius. (The link is in Resources.) The program window appears.
2. Click on Open Files to display the file dialogue. Search for the image to resize and double-click it. The dialogue closes as the image appears in the program window. The name, dimensions and resolution appear in the File List dialogue at the bottom right.
3. Click Resize Pictures to display the Resize dialogue.
4. Click a check mark into the Change DPI check box. Enter a new number into the New DPI box. This example changes the resolution to 72 DPI, which is the standard for web images.
5. Click the Process button to display the Output Format dialogue. Change any options, such as the destination folder, if needed.
6. Click the Process button to change the file. A dialogue confirms the process and asks if you want to open the output folder. Click the Yes button to display the contents of the folder. Double-click on the new file to open it so you can ensure its quality.
