Preparing a 33×48 mm visa photo
At 300 DPI, 33×48 mm is 390 × 567 pixels — narrower and taller than the usual 35×45 mm passport photo, so don't reuse one without re-cropping.
Head size. Chinese visa guidance has asked for the head to be about 28–33 mm tall and 15–22 mm wide, on a white or near-white background, with the face looking straight at the camera. Drag the preview until the head fills roughly 60–70% of the height.
Online applications may ask for a digital photo with its own pixel and file-size limits. If the form states pixels, use those; if it limits file size, use the compressor afterwards.
Rules change — always check the current requirements at the embassy or visa centre you are applying through.
Same size in cm: 3.3×4.8 cm.
