Choose ImagePixel rules are as common as file-size rules
Many sites reject images that are the wrong width or height even when the file is small enough. Profile photos, banners, product shots and document scans often need an exact box such as 300×80, 600×600 or 1920×1080.
Set both dimensions, lock aspect ratio to avoid stretch, or start from a common preset, then download the resized file.
Pair with compression when both limits apply
If the form also caps KB, resize first so the canvas matches the requirement, then open Compress Image to Exact Size. That order usually keeps faces and text clearer than compressing a huge photo and hoping the portal accepts it.
