What these numbers mean in practice
The square asset is required. Minimum 300 by 300 pixels, recommended 1200 by 1200, at most 5120 KB, as PNG or JPG. Google advises keeping important content within the centre 80% of the frame.
An asset below the minimum size is not eligible to serve, so the campaign runs without it.
How FileBelow applies them
Choosing this destination sets every rule above at once. After processing, the result panel shows one line per rule with a pass or fail beside it, so you can see that the file genuinely complies rather than hoping it does.
Where the specification sets a minimum size rather than an exact one, FileBelow keeps as much resolution as it can while meeting the other rules, and never scales below the stated minimum.
