What is the difference between cropping and resizing an image?
Cropping extracts a specific rectangular sub-region from an image and discards the surrounding outer margins, altering the visual composition and aspect ratio without altering individual pixel density. Resizing, in contrast, takes the entire image composition and scales all existing pixels up or down to fit new dimensions.
Key Takeaways
- Cropping changes composition and framing; resizing changes overall scale.
- Supports standard aspect ratios: 1:1 (Square), 16:9 (Widescreen), 4:3, and 9:16 (Stories).
- Freeform mode allows custom pixel bounding boxes without constraint.
- Original image quality is preserved within the cropped coordinate boundary.
