33×48mm Photo Maker
China's exact passport, visa, and permanent residence permit size.
33×48mm (3.3×4.8 cm) is the size the Chinese Exit-Entry Administration requires for the passport, every visa category — including the Z work visa — and the Permanent Residence Permit ("green card"). Our AI auto-crops your face to China's exact 70–80% head-height rule, removes the background, and exports at a print- and COVA-ready 300 DPI. Runs entirely in your browser — no upload, no sign-up.
How we keep your data private
Unlike other sites, we do not upload your photo to a server for processing.
- Local processing — AI models run directly in your browser using WebAssembly. No server-side code touches your photos.
- Zero data transfer — Your photo never leaves your device's memory. Nothing is sent, stored, or logged.
- Verify it yourself — Turn off your Wi-Fi after the page loads. The tool still works perfectly.

|---|---|---|
| 300 DPI | 390×567 px | Standard printing — the minimum for photo counters and home printers |
| 600 DPI | 780×1134 px | COVA digital upload and high-quality prints — downsizes cleanly to any portal minimum |
For comparison with other formats — the UK/EU 35×45 mm, the US 51×51 mm square, Canada's 50×70 mm — see the full passport photo size guide.
Documents that use 33×48 mm
4 documents in our database use the 33×48 mm format. The Chinese passport and visa share the same white-background spec; the Permanent Residence Permit uses the same dimensions but a light-grey background, so pick the exact document below rather than reusing one file for all three.
How many 33×48 mm photos fit on a sheet?
Chinese visa centers and consulates typically ask for 2 identical photos. With 5 mm page margins and 2 mm cutting gaps between photos:
| Paper size | Photos per sheet | Layout |
|---|---|---|
| 4×6" (10×15 cm) | 8 | 3 columns × 3 rows (partial) |
| A4 | ~35 | 7 columns × 5 rows |
| US Letter (8.5×11") | ~30 | 6 columns × 5 rows |
The editor's free print-layout feature arranges the copies on your chosen paper size with dashed cut lines, so one cheap 4×6 pharmacy print covers the 2-copy requirement with spares left over.
Frequently Asked Questions
What is 33×48 mm in pixels?
At 300 DPI — the standard print resolution — a 33×48 mm photo is 390×567 pixels. At 600 DPI it is 780×1134 pixels. China's Exit-Entry Administration and the COVA online visa portal both measure the printed or uploaded photo against this ratio, so cropping to the exact 390×567 px frame (rather than a generic passport-photo size) matters more here than for most countries.
What documents use a 33×48 mm photo?
The Chinese passport, all categories of Chinese visa — tourist (L), business (M), and the Z work visa — and the Permanent Residence Permit ("green card") all use 33×48 mm. The dimensions are identical, but the background color is not: the passport and visa presets use pure white, while the green card preset uses plain light grey. Thailand's APEC Business Travel Card happens to share the same 33×48 mm dimensions, though its rules otherwise differ.
Is 33×48 mm the same as a US or UK passport photo?
No. The US passport photo is 51×51 mm (2×2 inches, square) and the UK/EU standard is 35×45 mm — both the wrong proportions and the wrong head-to-frame ratio for a Chinese document. Chinese photos require the head (chin to crown) to fill 70–80% of the frame, taller than the 60–75% typical of most other countries, so a US or UK photo cropped down to 33×48 mm will usually fail the head-size check even if the outer dimensions are corrected.
Can I wear glasses in a 33×48 mm China photo?
No. China prohibited eyeglasses — including prescription glasses — from passport photos in 2023 and from visa photos in 2016. Sunglasses or tinted lenses are never accepted. Medical-necessity exceptions require a doctor's letter submitted with the application.
What background color does a 33×48 mm photo need?
It depends on the document. The Chinese passport and visa (including COVA digital uploads) require pure white — light grey, off-white, or beige are all rejected. The Permanent Residence Permit is the exception: it requires plain light grey. Pick the specific document preset in the editor so the background is generated correctly; do not reuse a white-background photo for the green card application.
How many 33×48 mm photos fit on one sheet?
With 5 mm margins and 2 mm cutting gaps, a 4×6 inch (10×15 cm) print fits 8 photos of this size, and an A4 sheet fits around 35. Chinese consulates and visa centers typically ask for 2 identical printed copies, so a single cheap 4×6 print covers the requirement with copies to spare.
