15 MB input, 25 megapixels, output dimensions 1–8,000 px with a 25-megapixel cap.

Resizing changes pixel dimensions rather than simply changing a file-size label. Downscaling reduces detail and usually saves space; enlarging cannot recover details absent from the original. Locking the aspect ratio keeps the image proportions intact.

1600 × 900 → 800 × 450 with the same aspect ratio.
