Singapore Passport Photo Size & Requirements

Some countries — the UK and Ireland among them — accept light grey or cream as well as white. Singapore's Immigration & Checkpoints Authority (ICA) is consistently described as white-only: even a slight off-white or grey tint is a commonly cited reason for a rejected photo. Stick to a plain white wall or sheet, evenly lit with no shadows falling across it.

ICA's own photo-guidelines page confirms the digital upload spec directly: 400×514 pixels, in JPG, JPEG, HEIC, HEIF, or PNG format, no larger than 8MB. Crop with the tool above first — it exports at 630×810px, which keeps the exact 35:45 ratio and comfortably clears ICA's stated minimum once scaled down for upload.

ICA publishes a digital upload specification of 400 by 514 pixels for its e-Services, and the print size everyone uses is 35 by 45 millimetres. It is reasonable to wonder whether those are two different crops. They are not. 400 divided by 514 is 0.778, and 35 divided by 45 is also 0.778 — identical to three decimal places. The digital spec is just the print size rendered at about 290 pixels per inch.

This is worth knowing because it is not true everywhere. Japan, for example, wants 600 × 730 pixels for its online channel, a visibly different shape from its own 35 × 45mm print size, and anyone who rescales one into the other ends up with a stretched face. Singapore has no such trap: one crop serves both channels, and you can print the same file you upload.

ICA accepts JPG, JPEG, HEIC, HEIF and PNG, up to 8MB. The HEIC and HEIF entries are a genuinely useful detail: those are the formats an iPhone produces by default, and most government portals still reject them outright, forcing a conversion step. Here you can upload what your phone gave you.

One nearby size worth not confusing this with: Malaysia's 35 × 50mm passport photo shares the same 35mm width and adds 5mm of height. That is close enough to look identical in your hand, and not close enough to pass an ICA check.

The recency window for an ICA photo is three months, half the six-month allowance most countries give, and the requirement is phrased as a true likeness of your current appearance. A photo from last year showing a different haircut, a beard you have since shaved, or a noticeably different weight is not a true likeness even if it is technically within some window.

The shorter window has a practical implication for families applying together. A set of photos taken for a school registration in January is not usable for a passport application in June, and if you are renewing passports for several people at once it is worth doing all the photos on the same afternoon rather than digging out whatever each person happens to have.

Several European authorities explicitly accept light grey or cream as alternatives to white. The United Kingdom does. Ireland lists three acceptable colours outright. Singapore does not offer that flexibility, and the consistent warning across every source consulted is that even a slight off-white or grey cast is enough to cause a rejection.

In a tropical, high-rise city this is harder than it sounds, because the most common indoor lighting situation produces exactly the failure mode in question. A white wall lit by warm ceiling lighting photographs cream. A white wall in a room with a strong colour on the opposite side picks up that colour as bounce. A white wall you are standing right against picks up your own shadow as grey. All three read as not-white to a reviewer looking at the file on a calibrated screen.

The reliable setup is diffuse daylight — an overcast day or a north-facing window, not direct sun — with you standing about a metre clear of the wall so your shadow lands behind you and out of frame. If you cannot get there, the background replacement in the cropper will flatten the backdrop to a true white, though a genuinely plain wall is always the safer option when the standard is this strict.

On clothing, the same principle applies in reverse: a white or very pale top against a white background leaves your shoulders invisible and your head apparently floating. Something with a clear colour and a defined collar reads much better.
