Chinese visa photos use their own size: 33 mm wide by 48 mm high — taller and narrower than the 35×45 most countries share — on a pure white background, printed borderless on glossy paper. The head must measure 28 to 33 mm high and 15 to 22 mm wide, with 3–5 mm of space above the crown and at least 7 mm below the chin, ears visible, and no head covering unless worn for religious reasons (and even then nothing may obscure the face). The first preset renders 33×48 at 600 DPI print resolution (780×1134). For the COVA online form the official window is exact: a JPEG between 354×472 and 420×560 pixels, weighing 40 to 120 KB — the two COVA presets are its floor and ceiling, and the compress-image-to-100KB tool lands the file inside the kilobyte range if your JPEG comes out too heavy.
Two China-specific tips before you size anything: don't wear white — the background must be white and clothing that matches it blurs your outline — and keep the photo recent, taken within the last six months, unedited (composites and retouching are rejection grounds). If COVA rejects your upload three times, the system lets you proceed and hand a compliant printed photo to the visa centre instead. As always here, the honest part: this tool resizes exactly and does nothing else. It won't whiten a background, uncover ears, or validate the head-size rules, and it warns rather than silently stretching a face when the crop doesn't match 33×48. Everything runs in your browser; a visa photo never leaves your device.

Frequently asked questions
What size photo does a Chinese visa require?
33 mm wide by 48 mm high on a pure white background — a different shape from the 35×45 mm most countries use, so a generic passport photo crop won't fit. The head must be 28 to 33 mm high and 15 to 22 mm wide, crown 3–5 mm from the top edge, chin at least 7 mm from the bottom. The print preset renders 33×48 at 600 DPI for exact-size printing on glossy paper.
What are the COVA online upload rules?
Exact and strict: a JPEG between 354×472 and 420×560 pixels, file size 40 to 120 KB, full colour. The two COVA presets hit the floor and ceiling of that window; if the file exceeds 120 KB, run it through the compress-image-to-100KB tool. These numbers are the visa spec only — Chinese passport online channels use different rules — and if COVA refuses the upload three times, you may proceed and submit a printed photo at the visa centre.
Why shouldn't I wear white in the photo?
Because the background must be white, and clothing that matches it makes your outline unclear. Also checked: ears visible, head uncovered (religious wear allowed if it hides no facial features), neutral expression with eyes open and mouth closed, and no thick-rimmed or tinted glasses or lens glare — clear lenses are fine.
Can this tool make my background white?
No — it resizes only, and says so rather than pretending. Chinese consulates reject edited or composite photos anyway, so take the photo against a white wall in even light first, then size it here. Nothing uploads anywhere: the resize happens entirely in your browser, which is where an identity photo belongs.
Is my file uploaded to a server?
No. ConvertUno runs entirely in your browser on your own device. Your file never leaves your computer or phone — there is no upload at all.
Is it really free, with no watermark?
Yes. Processing happens on your device, so serving you costs us almost nothing — no watermark, no account, no file-size limit, no daily quota.
