3×3cm Photo Maker
A true 30×30mm square — not to be confused with 30×40mm.
3×3cm (30×30mm) is an exact square photo format requested by specific institutional forms, membership cards, and some photo-booth presets. It is easy to confuse with the taller 30×40mm ("foto 3×4") rectangle, so if a form specifically asks for 3×3, use this exact square crop. Our AI centers your face, removes the background, and exports at a print-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.

3×3 cm photo specifications
- Dimensions: 30 mm × 30 mm (3×3 cm, ≈1.18×1.18 inches), an exact 1:1 square.
- Head size and background: not governed by a single official standard — use a plain light background and a centered, neutral-expression headshot unless your specific form publishes different numbers.
- Print resolution: 300 DPI minimum for photo-quality printing.
Pixel dimensions depend on the resolution you print or upload at:
| Resolution | Pixel dimensions | Best for |
|---|---|---|
| 300 DPI | 354×354 px | Standard printing — the minimum for photo counters and home printers |
| 600 DPI | 709×709 px | Digital uploads and high-quality prints — downsizes cleanly to any form's minimum |
Don't confuse this with the taller 30×40 mm (foto 3×4) rectangle used by India, Brazil, and Eastern Europe — or the larger 50×50 mm square. For every standardized country size, see the full passport photo size guide.
Which documents use 3×3 cm?
We checked our database of 233 government-issued passports, visas, and ID cards, and none of them specify exactly 30×30 mm — most square photo formats we track are the larger 50×50 mm or 51×51 mm (2×2 inch). 3×3 cm instead tends to show up on:
- Specific institutional or membership forms that request a square photo by name
- Some photocopy-shop and photo-booth presets marketed as a generic "3×3" square
- A small number of visa or ID applications outside our current database — treat any specific claim about a country requiring exactly 3×3 cm as unverified unless you confirm it on the issuing authority's own site
If your form doesn't specify a size and simply says "passport photo," it almost certainly means a standardized size — check the size guide or browse all supported documents before assuming 3×3 cm.
How many 3×3 cm photos fit on a sheet?
Being small and square, this size packs efficiently onto a sheet. With 5 mm page margins and 2 mm cutting gaps:
| Paper size | Photos per sheet | Layout |
|---|---|---|
| 4×6" (10×15 cm) | ~12 | 3 columns × 4 rows |
| A4 | ~56 | 7 columns × 8 rows |
| US Letter (8.5×11") | ~48 | 6 columns × 8 rows |

Frequently Asked Questions
What is 3×3 cm in pixels?
At 300 DPI — the standard print resolution — a 3×3 cm (30×30 mm) photo is 354×354 pixels. At 600 DPI it is 709×709 pixels. Because it is a perfect square, width and height are always identical at any resolution.
Is 3×3 cm the same as 30×40mm (foto 3×4)?
No — this is a common mix-up. 30×40 mm ("foto 3×4") is a portrait rectangle, 10 mm taller than it is wide, used across much of India, Brazil, and Eastern Europe. 3×3 cm (30×30 mm) is an exact square, 30 mm on every side. If a form asks for "3×3", it means the square format — cropping the bottom off a 3×4 rectangle photo will not produce a correct 3×3 square, because the head position and margins are calculated differently for each shape.
Which documents require a 3×3 cm photo?
Unlike 35×45 mm or the US 2×2 inch format, 3×3 cm is not a single country's official passport or visa standard in our database — we checked and found no passport, visa, or national ID in our 233-document database that specifies exactly 30×30 mm. It shows up instead as a requirement on specific institutional forms, membership or access cards, and some photo-booth presets that ask for a square photo by name. A small number of third-party photo-service directories cite Bolivia's national ID card and visa applications, and Panama's seaman's passbook, as using 3×3 cm — we have not been able to confirm this against a primary government source, so verify the current requirement with the issuing authority before relying on it. If your form simply says "passport photo" without a size, it almost certainly means a different, more common format — check the size guide below.
What background and head-size rules apply to a 3×3 cm photo?
There is no single official rule set the way there is for a country's passport photo, since 3×3 cm is used by many different forms and institutions rather than one authority. As a safe default: use a plain white or light background, a neutral expression, and center the head with a small margin on every side — the same conventions almost every ID-photo authority follows. If your specific form publishes exact head-height or margin numbers, follow those instead.
How do I make an exact 3×3 cm square photo?
Use the editor's custom-size tool: set both width and height to 30 mm, upload your photo, and the AI positions and crops your face into an exact square automatically. The export is a true 30×30 mm frame at your chosen DPI — no manual measuring or cropping software required.
How many 3×3 cm photos fit on one sheet?
Being small and square, a lot fit on one sheet. With 5 mm margins and 2 mm cutting gaps, a 4×6 inch (10×15 cm) print fits about 12 photos, and an A4 sheet fits around 56 — useful if you need several copies for multiple forms or family members.
