Why Resize Images?

Image resizing is essential for various purposes, from optimizing web performance to preparing images for specific platforms. Here's why you might need to resize your images:

Understanding Image Dimensions and Resolution

When resizing images, it's important to understand these key concepts:

Pixel Dimensions

Refers to the width and height of an image measured in pixels (e.g., 1920×1080). More pixels mean a larger image and potentially more detail.

Resolution

Measured in pixels per inch (PPI) or dots per inch (DPI), resolution determines how densely packed the pixels are. Higher resolution images appear sharper when printed.

Aspect Ratio

The proportional relationship between an image's width and height (e.g., 16:9, 4:3, 1:1). Maintaining aspect ratio prevents distortion.

File Size

Measured in kilobytes (KB) or megabytes (MB), file size is influenced by dimensions, format, and compression level.
