What “file too large” actually means
Upload limits are measured in bytes. A portal can reject a perfectly valid file simply because it is larger than the published maximum.
Reducing dimensions or image quality can lower file size dramatically.

What does file too large mean?
It means the file contains more bytes than the receiving portal allows.
How do I know how much smaller the file must be?
Enter the portal limit and Ninjitzu compares that limit with the current file size.
Should I aim exactly at the limit?
It is safer to leave some margin below the published maximum.
