Common mistakes
Too much compression
Very small KB targets can make faces, signatures or document text unclear.
Wrong dimensions
Many portals reject files when the KB is correct but pixel size or aspect ratio is wrong.
Skipping the final check
Open the final file once before upload so you catch blurry output or the wrong format.
Using portal-unapproved backgrounds
Some forms need white or plain backgrounds, even if the photo size is correct.
