How to change aspect ratio without cropping?

To change aspect ratio without cropping, you need to add borders or padding instead of cutting content. Here's everything you need to know.

The Core Concept:

When changing aspect ratio without cropping, you preserve all original content by adding:

  • Black bars (letterboxing/pillarboxing)
  • Colored borders (custom background)
  • Padding (empty space)

This method preserves 100% of the original image or video.
