What is Aspect Ratio?
Aspect ratio describes the proportional relationship between the width and height of a rectangle (like a screen or an image). It is commonly expressed as two numbers separated by a colon, such as 16:9. This tool helps you maintain a consistent aspect ratio when resizing images or video, which is crucial for preventing distortion in responsive web design and video editing.
