Image Resize Calculator
Resize dimensions proportionally without changing the original image shape. Enter your original width and height, then use the percentage controls in the main calculator.
Why proportional resizing matters
Scaling width and height by the same factor prevents stretching and squashing. A 1920×1080 image scaled to 50% becomes 960×540 and remains 16:9.

New width = original width × percentage ÷ 100. New height uses the same factor. Rounding to whole pixels is appropriate for ordinary raster images.
