Cambodia eVisa Photo Size & File Format: US Guide

Đang tải…

The size-and-file spec, and the iPhone trap behind it

Below: the exact pixel and size targets, the millimeter-to-inch conversions Americans keep searching for, the JPEG-versus-HEIC question in plain terms, and how to compress an oversized file without wrecking it. If you want the composition rules first — background, expression, the no-glasses rule — start with our full photo requirements guide for US citizens, then come back here for the file mechanics. When everything is squared away, you can apply in a few minutes.

Pixels, dimensions, and the numbers that matter

Why 600×600 is the number to remember

Square is the safest aspect ratio

One question Americans ask a lot is whether to use the US-style 2×2 inch passport photo or the international 35×45 mm size. For a digital eVisa upload the print dimension barely matters — pixels and file size are what the form reads — but a square crop maps cleanly to the familiar US 2×2 shape, which is why it is the easiest target. Our breakdown of the 2×2 versus 35×45 mm question covers the conversions if you also need a printed photo for something else.

JPEG vs HEIC: the iPhone format trap

Android users rarely hit this — most Android phones save JPEG straight out of the camera, so the format is a non-issue. The other format that catches Americans is the screenshot: a photo screenshotted off a screen saves as PNG, which the form also rejects, and screenshots are usually low-resolution besides. Use the real photo file, exported as JPEG. Our iPhone photo guide for Americans walks through the HEIC-to-JPEG steps with screenshots if you want to see exactly where each setting lives.

When the file is too big: compressing under 2 MB without wrecking it

Crop to a square first. Cropping away the extra width and height of a portrait photo removes pixels you do not need and often drops the file under 2 MB on its own — no quality loss in what remains, because you are deleting background, not compressing your face.
Resize to around 600 to 1000 pixels on the short side. A square photo at roughly 600-1000 pixels is comfortably above the resolution floor and almost always well under 2 MB. Your phone's Photos editor or any basic resize tool handles this in seconds.
Re-save as a JPEG at slightly lower quality. JPEG is a lossy format, so saving at 80-90% quality cuts the file size meaningfully while staying visually clean. Avoid dropping below about 70%, where compression artifacts start to show on the face and the validator can flag a degraded image.

If your file keeps coming back too large no matter what you try, the most common culprit is uploading the original full-resolution image without cropping it first. Our guide to compressing a Cambodia visa photo that is too large walks through the exact tools on iPhone, Android, Mac, and Windows, with target settings for each. For most Americans, a square crop straight from the phone is all the compression you ever need.

Your 30-second file check before you hit upload

Is it a JPEG? Confirm the file name ends in .jpg, not .heic or .png. This is the number-one US flag, and it is invisible until the form rejects it.
Is it square? A 1:1 crop with your head centered, a little headroom above, and your shoulders showing at the bottom.
Is it at least 600 pixels on the short side? If you cropped or resized, double-check you did not drop below the floor.
Is it under 2 MB? Most cropped square JPEGs land well under; if yours is over, crop tighter or resize before compressing.
Is it the original, not a re-shared copy? A photo pulled from a text thread or group chat may be compressed below the resolution floor. Use the file straight from the camera roll.
No filter, no beauty mode? Heavily smoothed skin reads as a manipulated image. Natural skin texture passes; processed photos get flagged.

If the photo does come back flagged, it is not a denial — you re-upload a corrected version at no extra charge and the 3-business-day clock keeps running. Our guide to fixing a rejected Cambodia eVisa photo maps each flag to its exact fix, and the printable photo checklist for US citizens condenses this whole list onto one card you can keep open while you shoot.

Get the file right, then apply

Next steps and related reading for Americans: apply for your Cambodia eVisa once your photo is a square JPEG under 2 MB, review the full photo requirements guide for US citizens for the background and expression rules, see where the photo sits inside the required documents list for Americans, and bookmark our Cambodia visa hub for US citizens as the single reference for cost, documents, and timing.

Câu hỏi thường gặp

What size does the Cambodia eVisa photo need to be for Americans?

A square image at least 600×600 pixels. The printed passport equivalent is 4×6 cm (about 1.6×2.4 inches), but you never print it — the Cambodia eVisa is fully digital, so the form reads pixels, not centimeters. Stay at or above 600 pixels on the short side and crop the image square, and the dimension check passes.

What file format does the Cambodia eVisa photo have to be?

A JPEG (.jpg). The form does not accept HEIC, the format recent iPhones save by default, and it does not accept PNG screenshots either. If you use an iPhone, switch the camera to "Most Compatible" before you shoot, or convert the finished photo to JPEG before uploading. Android phones generally save JPEG out of the box.

How many MB can the Cambodia eVisa photo be?

Under 2 MB. A full-resolution phone photo often runs three to eight megabytes, well over the ceiling, so a compliant headshot can get bounced for size alone. Crop the photo to a square first — that usually drops it under 2 MB on its own — and resize or lightly compress only if it is still too large.

Is the Cambodia eVisa photo 2×2 inches or 35×45 mm?

Neither dimension is something you measure, because the eVisa photo is never printed. The quoted print spec is 4×6 cm (about 1.6×2.4 inches), but the upload form checks pixels and file size, not inches or millimeters. A square crop maps cleanly to the familiar US 2×2 inch shape, which is why square is the easiest target to aim for.

Why does my iPhone photo keep getting rejected by the Cambodia eVisa form?

Almost always because it is a HEIC file, not a JPEG. Recent iPhones save HEIC by default, and the upload form will not accept it no matter how good the photo is. Convert it to JPEG — email it to yourself, use a "Save as JPEG" option, or open it in Preview on a Mac and export — or change the camera to "Most Compatible" and re-shoot. The other common cause is a file over the 2 MB size limit.

How do I compress my Cambodia visa photo to under 2 MB?

Crop it to a square first, which removes background pixels and often drops the file under 2 MB on its own. If it is still too big, resize the short side to around 600 to 1000 pixels, then re-save as a JPEG at 80-90% quality. Avoid compressing below about 70% — that introduces visible artifacts the validator can flag as a degraded image. Aim to land between roughly 200 KB and 2 MB.

Can I upload a screenshot of my photo for the Cambodia eVisa?

No. Screenshots save as PNG, which the form rejects, and they are usually low-resolution besides — often below the 600-pixel floor. Always upload the original photo file from your camera roll, exported as a JPEG. The same caution applies to photos pulled from a text thread or group chat, which messaging apps compress below the resolution limit.

What happens if my Cambodia eVisa photo is the wrong size or format?

The upload form flags it before submission, or it comes back for a correction — and either way it is not a denial. You re-upload a corrected version at no extra charge and the 3-business-day clock keeps running. The usual fix is converting a HEIC to JPEG, cropping to a square, or compressing an oversized file under 2 MB. Free resubmission is part of the all-in price.
