Enhancements or Suggestions:
Validation: Ensure that the width and height inputs are valid (i.e., positive integers) before resizing.
Aspect Ratio: Optionally, you could lock the aspect ratio when resizing, making the process more intuitive (by either keeping one dimension fixed or automatically calculating the other).
Drag-and-Drop: Consider adding a drag-and-drop feature for uploading images, which can enhance user experience.
Loading State: Add a loading indicator for resizing, especially for large images, so users know the tool is working.
