A 390 x 567 px photo is 33 x 48 mm
390 x 567 px at 300 DPI is 33 x 48 mm (1.3 x 1.89 in). The Chinese passport and visa format, 33 x 48 mm, at 300 DPI. The COVA online form accepts 354-420 px wide by 472-560 px tall, so this sits inside its window with margin on every side.
Cropping to 390 x 567 px by eye is not enough on its own, because the pixel count says nothing about where your head sits inside the frame — and the head height is what most refusals turn on. Choose the document below and both are handled: the export lands at the right pixel count and the head is aligned to the range the authority publishes.
