Distortion is the most common problem when resizing: the image appears stretched or squashed, faces become oval, circles become ellipses.
This problem occurs when the aspect ratio (width to height ratio) is not maintained during dimension changes.
Discover techniques to resize your images while perfectly preserving their proportions.

Understanding Image Distortion
Distortion occurs when width and height aren't modified proportionally.
Example: a 1000x500 image (2:1 ratio) resized to 800x600 will be distorted.
The aspect ratio must remain constant to avoid this problem.
Aspect Ratio Explained
Aspect ratio is the relationship between width and height.
Common ratios: 16:9 (HD video), 4:3 (classic photo), 1:1 (square), 3:2 (DSLR).
To preserve shape, this ratio must remain identical after resizing.
Methods to Avoid Distortion
Lock proportions: modify one dimension, the other adjusts automatically.
Use percentage: reduces both dimensions uniformly.
Crop if needed: adapt content to new ratio.
What If Target Ratio Differs?
Option 1: Crop the image for the new ratio.
Option 2: Add borders (letterboxing) to fill.
Option 3: Content-aware scaling.
Never stretch: distortion is always visible.
