Image Size and Quality
A 2 MB photo file has about 2 megapixels. This size is good for printing 6 by 4 inches. High resolution photos are over 1 MB due to more pixels. For printing, JPEG files should be 300 pixels per inch (PPI). Hi-res images have at least 300 PPI, providing better quality prints.
Reducing Photo Size
To reduce photo size:
- Lower the megapixels in your camera settings.
- Compress images in an application.
A typical low resolution photo is 175 KB and only requires 72 PPI, which suffices for web images. For instance, an iPhone photo is almost 3 MB, while a 4-inch iPhone photo occupies approximately 1.3 MB of space.
Managing Document Size
A 4 MB Word file is small for a document but can be cumbersome to process. Interestingly, one MB can contain over 500 pages of text.
To make a photo file 2 MB:
- Cut pixels using photo editing software.
- Reduce the image size by adjusting the percentage.
- Save the image as a JPEG.
