Image Resizer

Utility: Quickly resize images to exact dimensions, a percentage of the original, or popular social media sizes — without uploading anything.

Definitions:
- Aspect Ratio: The proportional relationship between width and height (e.g. 16:9).
- Interpolation: The algorithm used to calculate new pixel values when resizing.

Technical Background: ImageMagick uses high-quality Lanczos resampling by default, producing sharp results even when scaling down significantly.

Fun Fact: The most common social media image size is 1080×1080 for Instagram posts, but stories use 1080×1920 — a 9:16 ratio!
