How to use the Image Aspect Ratio Changer
Select a photo and set the ratio and output width. Cropping excludes part of the scene relative to the center, while adding margin preserves the entire scene. Compare the two results and save them.
Example usage
If you change a 1600×900 photo to 1200×900 4:3, center cropping excludes the sides, and adding margins reduces the entire photo to create space at the top and bottom.
Please note
Supports PNG·JPEG·WebP still images, 20MiB per file, 16 million pixels, and up to 8192px on each side. The output also applies the same pixel limits. Zooming in does not restore the details of the original. Animation and metadata preservation are not supported.
