When an image is uploaded, WP can create a crop that has a larger filesize than the original. WP will then default to using the crop when the media is inserted, thus increasing the page size.

Steps to reproduce

1. Set a WP image size to 512x512
2. Create a 512x512 PNG with maximum compression
3. Upload the image to the media library
4. compare image.png and image-512x512.png, the latter is likely to have a larger file size.
