Passport and visa photo requirements, decoded

The rules are oddly specific and rarely explained. Here is each one, what it is actually checking for, and how to satisfy it with a photo you already have.

A passport photo is one of the few pictures you will ever take that gets judged twice — once by software counting pixels and bytes, and once by a person looking at your face. Both can reject it, and they reject it for entirely different reasons.

Most upload failures are not about how you look. They are arithmetic. A photo that is a few pixels short of the minimum, a file a few kilobytes over the cap, a rectangle where a square was demanded, a PNG where only JPEG is accepted. These are fixable in a couple of minutes once you know which number you are failing and in what order to fix them.

The figures below are the United States ones, as published by the Department of State. Other countries set their own — many use a 35 × 45 mm print, which is a different shape entirely — so check the authority you are actually applying to. What follows is guidance on hitting published numbers, not legal advice, and the issuing authority has the final say on whether a photo is accepted.

What each requirement is actually checking for

The rules look like an arbitrary pile until you sort them into the three things they protect. Once sorted, most stop being surprising.

Measurability of the face. The head must occupy a specific fraction of the frame, the pose must be directly frontal, the expression neutral, and both eyes open. This is not aesthetics. Automated systems locate landmarks — pupils, nose, mouth corners, the outline of the jaw — and measure the distances between them. A head too small in the frame has too few pixels across the eyes to measure reliably; a head too large risks the crown or chin falling outside the picture; a turned head compresses those distances unpredictably. It is also why eyeglasses, sunglasses, hats and face coverings are excluded, other than for documented religious or medical reasons: they occlude exactly the region the measurement depends on.

Separability of subject from background. The background must be plain white or off-white and free of shadows, textures or objects. A shadow falling behind your head produces a dark edge that looks, to an edge detector and to a tired reviewer alike, like part of your outline. A patterned wall does the same with more enthusiasm. The point of the white wall is that there is nothing in the picture except you.

Honesty of the image. The photo must have been taken within the last 6 months, and it must be an unedited original — no filters, no digital alterations. The document is supposed to depict a person as they currently are, which rules out both an old photograph and a retouched one.

The remaining rules — pixel dimensions, file format, file size, colour depth — are not about you at all. They exist so the receiving system can store, transmit and process the image predictably. They are also, in practice, where most submissions fail, because they are the ones you cannot judge by looking.

The numbers, digital and printed

There are two distinct specifications, and which one applies depends on how you are submitting. An online application wants a digital file. A paper application, or many in-person appointments, want a physical print. The framing rules are the same; the measurements are expressed in different units.

The head-size rule is stated in inches even for the digital file, because the digital photo is specified as though it were the 2 × 2 inch print. Converting that into pixels is the most useful piece of arithmetic here, and it comes further down.

Why the pixel rule and the size rule fight each other

Four digital constraints apply at once: square shape, 600–1200 px, JPEG, and 240 KB or less. Individually each is trivial. Together they form a squeeze, and the squeeze gets tighter the more resolution you ask for.

Work out the raw size of the image before compression. At 24 bits per pixel, every pixel costs 3 bytes. A 600 × 600 image is 360,000 pixels, or roughly 1.08 million bytes uncompressed. A 1200 × 1200 image is 1.44 million pixels — around 4.32 million bytes. Four times the area, four times the raw data.

Now apply the two byte rules together. The file must be no larger than 240 KB, and the compression ratio should not exceed 20:1 — meaning the file should not be squeezed to less than a twentieth of that raw size. At 1200 × 1200, a twentieth of 4.32 million bytes is about 216 KB. So a maximum-resolution photo has to land somewhere between roughly 216 KB and 240 KB. That is a narrow corridor, and no quality slider will find it by feel.

Run the same sum at the bottom of the range and the picture changes completely. A twentieth of 1.08 million bytes is about 54 KB, so a 600 × 600 photo has a comfortable range from roughly 54 KB up to the 240 KB ceiling. Lower resolution buys you slack on both byte rules at once.

This is the genuine trade-off in the specification. More pixels means a clearer face, but it pushes you against the byte cap and leaves almost no room. Fewer pixels means an easy fit but less detail to measure. A sensible landing zone is the middle of the permitted window rather than either edge — enough resolution to be legible, enough headroom that a modest quality setting stays under the cap without visible damage.

The head-size rule, translated into pixels

The rule says the distance from the bottom of the chin to the top of the head must be between 1 and 1-3/8 inches on a 2-inch photo. Expressed as a fraction of the frame, that is between one half and just over two thirds of the total height. Because the photo is square, the same fractions apply whatever pixel size you choose.

In a 600 × 600 image, the chin-to-crown measurement should therefore fall between roughly 300 and 412 px. In a 1200 × 1200 image, between roughly 600 and 825 px. Aiming near the middle of that band gives you room for error in either direction.

Two details matter when you measure. “Top of head” means the top of your head including hair, not the hairline. And the head should sit roughly centred left to right, with the eyes above the vertical midpoint rather than below it — a face floating in the bottom half of the square is a common and easily avoided failure.

Pick your square by eye so that the head fills a little more than half the height, then check the numbers against the bands above before you commit. If your original does not contain enough room above the head to make a legal square, no crop will save it — that one needs re-shooting.

What “unedited original” actually forbids

This rule catches more people than it used to, because modern phones edit photographs without being asked. The requirement is that the submitted image is an unedited original: no filters, no digital alterations to the content of the picture.

In practice that rules out beauty and smoothing modes, skin retouching, blemish removal, teeth or eye whitening, slimming effects, background replacement or blur, colour grading and filters of any kind. It also rules out the friendlier-sounding operations — the automatic enhance button, red-eye correction — because they change what the picture says about you.

What it does not forbid is fitting the file to the specification. The requirements themselves demand a square crop, a particular pixel range, JPEG format and a size under 240 KB, none of which an untouched camera file will satisfy on its own. Cropping, resizing, converting format and compressing are mechanical steps that reframe and re-encode the image without altering its content. The line is between changing the container and changing the face.

Meeting all four constraints, in the right order

The order below is not a preference. Each step changes the input to the next one, and doing them out of sequence either wastes the byte budget or damages the image twice.

1. Start from the original file. Not a version you already compressed, not a screenshot, not something pulled out of a messaging app — those have been re-encoded and often resized on the way through. Go back to the camera roll.
2. Crop to a square. Position it so the chin-to-crown distance lands between half and two thirds of the frame height, and the head is centred horizontally. This is where you decide what the picture contains, and it must happen before anything measures bytes.
3. Resize into the 600–1200 px window. If your crop came out larger than 1200 px square, scale it down. If it came out smaller than 600 px, do not scale it up — enlarging invents detail that was never captured, and the result looks soft in exactly the region the check cares about. Re-crop from a higher-resolution original instead.
4. Save as JPEG in sRGB, 24-bit colour. Most cameras and browsers produce sRGB by default; the trap is a phone set to save HEIC, or an image carrying a wide-gamut profile from an editing app. Convert to JPEG explicitly rather than renaming the file.
5. Compress to 230 KB or less. Only now, with the final pixels decided, does the byte target mean anything. Aim under the cap rather than exactly at it, and keep the 20:1 guidance in mind — do not crush the file far below the limit just because you can.

If the file still will not fit after step five, the answer is to go back and reduce the pixel dimensions, not to keep lowering quality. A 900 × 900 photo at a comfortable quality setting will look better, and measure better, than a 1200 × 1200 photo crushed until the face has visible blocking artefacts around the eyes and mouth. Compression damage is concentrated exactly where the detail is, which on a portrait is the face.

If you are having a photo printed rather than uploading one, the digital constraints do not apply — there is no 240 KB cap on a piece of paper. What matters is that the print is 2 × 2 inches with the head sized correctly within it, on photo-quality paper. Send the printer the highest-resolution square crop you have.

Common questions

Can I take the photo on a phone? Yes — but have someone else take it. The Department of State is explicit that a selfie is not acceptable, however good the camera, and that alone accounts for a good share of rejected phone photos. Beyond that, disable portrait mode and any beauty or smoothing filter first, and shoot against a plain white or off-white wall in even light with no shadow falling behind you. Modern phone cameras easily exceed the resolution needed; the failure points are the automatic processing and the background, not the sensor.

My photo meets every number and was still rejected. What now? Then the failure was one of the human-judged criteria rather than the file: a shadow on the background, a head turned slightly off-frontal, an expression that is not neutral, glare on the eyes, or hair across the face. Re-shoot rather than re-edit — editing the existing photo would breach the unedited-original rule and does not fix a shadow anyway.

Does converting HEIC to JPEG count as editing? No. That is a format conversion, and JPEG is a stated requirement, so it cannot be what the rule forbids. The same reasoning covers cropping, resizing and compressing to meet the published limits. What is forbidden is altering the content of the picture.

Why can I not just upscale a small photo to 600 px? Because upscaling produces pixels without producing detail. The image will satisfy the dimension check and then fail the thing the dimension check exists to protect — a face with enough real resolution to measure. A photo below 600 px square needs re-taking, or re-cropping from a larger original.

My file is 1200 × 1200 and stubbornly over 240 KB. What is the fix? Reduce the pixel dimensions rather than pushing quality down further. Dropping to somewhere around 900 × 900 removes roughly half the data before compression even starts, which usually resolves the problem with a quality setting that leaves the face clean.

Are the requirements the same everywhere? No. The dimensions, file size limits and framing rules in this article are the US ones. Other countries publish their own, often with a different photo shape and different head-size bands. Always read the specification for the authority you are applying to, and treat the numbers there as the ones that count.
