Cambodia eVisa Photo Size and File Format for Americans: Pixels, MB, and JPEG vs HEIC
A square JPEG, at least 600×600 pixels, under 2 MB. That is the entire Cambodia eVisa photo size and file spec for Americans in 2026 — and the iPhone HEIC default is the one thing that quietly bounces the most US files at upload.
What size and file format does the Cambodia eVisa photo need to be for Americans?
A square image at least 600×600 pixels, saved as a JPEG (.jpg), with the file size under 2 MB. 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 pixels and the file size are what the upload form checks. The single most common format problem for Americans is the iPhone HEIC default: recent iPhones save photos as HEIC, not JPEG, and the form rejects HEIC. Switch the camera to "Most Compatible" before you shoot or convert the finished photo to JPEG, crop it to a square, and confirm the file is under 2 MB.
Wichtigste Erkenntnisse
- Target a square photo at least 600×600 pixels, saved as a JPEG (.jpg), with the file under 2 MB. A square crop is the safest aspect ratio for the upload form.
- The printed passport size is 4×6 cm — that is about 1.6×2.4 inches — but you never print it. The Cambodia eVisa is fully digital, so pixels and file size are what actually matter.
- JPEG only. The biggest format trap for Americans is the iPhone HEIC default, which the upload form will not accept — switch to "Most Compatible" or convert before you upload.
- Too big is as common as too small. A full-resolution phone photo can run 3 to 8 MB; a square crop or a light compression brings it comfortably under the 2 MB ceiling.
- PNG screenshots, re-shared photos from messaging apps, and files under 600 pixels are the three sneaky size-and-format flags — always upload the original JPEG.
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.
Millimeters, inches, and the print size most Americans never use
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.
Häufig gestellte Fragen
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.
Welches Dateiformat muss das Foto für das kambodschanische e-Visum haben?
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.
