One upload, two deliveries: the pixel-exact digital file and a 300 dpi print-ready sheet.
What each line means
Printed size — print at exactly 30 × 40 mm. A few millimetres off and most offices hand the form back before anything else is checked.
Digital size — the digital file must measure 354 × 472 px. Anything smaller gets refused by many online systems before a person sees it.
Background — a plain White background, with no shadows or gradients. A wall lit unevenly is the fastest route to a refusal.
Resolution — 300 dpi keeps a face sharp in print. Below that, features soften and agencies ask for a retake.

How to take a 30x40mm Photo with your phone
Photo size on order forms
30×40 mm is a small photo rectangle used on order forms and registration slips. No single document page here mandates it. It is the size named on studio order forms, exam registration slips and application paperwork that ask for a "small photo" and specify the millimetres beside it.
Matching the form's stated size
When the form in your hand says 30×40, this page makes it. When it says 33×48 or 35×45, the Chinese-system and world-standard pages make those. The three sizes are within a few millimetres of each other, and none substitutes for another.
Setup and lighting
Use a plain white wall, frontal light, and the camera at eye level. On a rectangle this small, the head fills proportionally more of the frame. Centre it before you shoot because the crop leaves nothing to spare.
Output from this page
The preset crops to the exact 30×40 mm rectangle on white at print resolution. Head position, background and ratio are checked before export.
Why 30x40mm Photo gets rejected
Difference from 33×48
Three millimetres of width and eight of height separate this size from the Chinese-system 33×48, and forms notice both. A "small photo" from the wrong page comes back from the counter as the wrong photo.
Cropping wide originals to fit
Squeezing a wide original into 30×40 by trimming the top of the head or the shoulders fails twice: the head loses its margin and the shoulders lose their line. Crop from a portrait original with room to give.
The ordinary faults
Shadows, tilts and off-white walls are standard refusals. On a canvas small enough to make each one decisive.

Photo tips
Frequently asked questions
What size is a 30x40mm Photo?
The standard size is 30 × 40 mm (354 × 472 px at 300 DPI). The tool crops and scales your photo to exact requirements automatically.
Can I smile in the photo?
Requirements call for: a natural expression. When in doubt, keep a neutral face with both eyes open.
How recent must the photo be?
Old photos are a common rejection reason.
Is my photo private?
Yes. Uploaded photos are encrypted in transit and automatically deleted within 24 hours. We never share or resell uploads.
Can I take it with my phone?
Yes. A plain white wall, even light and an eye-level phone cover it; the tool handles the exact small-format crop.
Is 30×40 mm close enough to 35×45 mm?
No — the rectangles differ and forms check dimensions exactly; use the preset that matches your form.
