Preparing Your Chinese Seafarer's Certificate Photo
You need a specific digital photo when you apply for a Chinese seafarer's certificate. The Jiangsu Maritime Safety Administration and Shanghai Maritime Safety Administration set strict rules for your image[1][2].
Official Size and Pixel Dimensions
The official size for your seafarer's certificate photo is 30 by 40 millimetres, which equals 1.18 by 1.57 inches[1][2]. When you prepare the digital file for your application, it must measure exactly 354 by 472 pixels[1]. The rules set precise boundaries for your head position within those pixels.
The head height must be 27 to 31 millimetres, the top margin 1 to 3 millimetres, and the eye line 20 to 28 millimetres from the bottom of the photo[1].
Background and File Format Rules
The background behind you must be a pure white background with no patterns, textures, or shadows[1]. Your digital image must be saved in the JPEG format using 24-bit RGB colour[1].
The file size must be 20 to 60 KB[1].
Clothing and Headwear Rules
When you sit for your photo, you must follow the rules regarding what you wear on your head and body. Official regulations state that headwear is not permitted in your seafarer's certificate photo[1].
The supplied photo rules say headwear is not permitted[1].
Submission Guidelines and Who Takes the Photo
Jiangsu guidance asks applicants to bring a standard electronic photo to a maritime agency for information collection[1].
In many cases, the issuing office may choose to reuse a photo that is already stored in the existing crew management system[1]. If you need to supply a new image, you must check that it matches the strict pixel dimensions, file size limits, and layout rules required by the maritime safety administration[1].
Step-by-Step Guide to Taking Your Photo at Home
You can easily capture your photo at home by following a few practical steps. Find a clean, brightly lit room and stand in front of a plain white wall to match the background requirement[1].
Face a large window to get even natural light on your face, or use two soft lights placed at equal angles to prevent harsh shadows. Ask another person to take the picture using a smartphone or digital camera held at your exact eye level. Keep the camera about one to one and a half metres away from your face to avoid any lens distortion. Stand straight, relax your shoulders, and look directly into the camera lens with a neutral posture.
Reviewing Your Image Before Upload
Before you upload your digital portrait to the application portal, take time to check every requirement. Verify that your head height measures between 27 and 31 millimetres and that your file size is safely between 20 and 60 kilobytes[1].
You can use the tool above to crop your raw picture to the proper 30 by 40 millimetre dimensions right in your browser. Always remember that the maritime authority makes the final decision on whether your submitted photo meets their standards[1][2]. Careful preparation reduces the chance of rejection and helps your paperwork move forward.
Common Reasons Photos Are Refused
The Jiangsu guidance specifies a file size of 20 to 60 KB and dimensions of 354 by 472 pixels[1].
Other refusals happen when the background contains shadows or off-white colours instead of the required pure white background[1]. Wearing prohibited headwear or having your head positioned too high or too low will also cause the system to reject your file[1]. Double-checking your measurements against the official specifications before you submit will save you time and prevent application delays.
