How to Resize an Image to Exact Dimensions
Change pixel dimensions for websites, shops and social assets while keeping proportions and important details under control.
How to use Resize Image
- Check the source dimensions and choose the final canvas width and height, from 1 to 12000 pixels each.
- The whole image is fitted in proportion. Different aspect ratios add white padding; use Crop Image first for an edge-to-edge fill that removes part of the source.
- Download the still-image result and check its canvas dimensions, padding and sharpness. Animation is not retained; upscaling cannot recover missing detail.
