The exact technical specs the Cambodia eVisa portal expects from Aussie applicants: 35×45mm equivalent at 300dpi, JPEG only, 100KB to 2MB, no EXIF rotation. Here is how to check, how to convert from HEIC, how to resize, and how to dodge the iPhone Live Photo trap that catches Aussies every week.

35mm by 45mm at 300 dots per inch — about 413 by 531 pixels at the minimum, 1200 by 1600 pixels at the upper end the validator will accept. JPEG only (.jpg or .jpeg, treated identically). HEIC and PNG are rejected on upload. File size must sit between 100KB and 2MB. The EXIF rotation flag must be off — meaning the photo is stored portrait the way it looks on screen, not rotated by the camera's metadata. On a Mac, check the pixel dimensions via Preview's Tools > Show Inspector panel. On Windows, right-click the file and open Properties > Details. The most common Aussie fail in 2026 is the iPhone HEIC format slipping through after a Live Photo AirDrop — convert to JPEG explicitly via the iOS Files app or macOS Preview before you click upload. Tourist eVisa is $80 USD (~$122 AUD) all-in, approved in 3 business days, delivered as a printable PDF by email, with free resubmission if Immigration flags a correction.

The 80-percent quality sweet spot
If your JPEG is bigger than 2MB but the pixel dimensions are fine, save a copy at 80 percent quality. JPEGs at 80 percent typically halve the file size without visible quality loss on a passport-style photo. On Mac, use Preview's File > Export > Quality slider. On Windows, the Photos app's resize tool handles this too. The validator does not care about the compression percentage, only the resulting file size and format.

Do not rename the file extension manually

First trip to Cambodia? Here is the honest first-timer checklist for Americans — the visa, the US-dollar money quirk, the safety reality, the vaccines, the temple dress code, and what arrival at the new airport actually looks like in 2026.

کمبوڈیا کے دارالحکومت اور انگکور واٹ کے درمیان 195 میل کا فاصلہ طے کرنے کے تین طریقے: $15 میں ایکسپریس بس، 45 منٹ کی پرواز، یا آہستہ دریائی کشتی۔ یہاں بتایا گیا ہے کہ ہر ایک کی اصل قیمت امریکی مسافر کے لیے کتنا ہے، اس میں کتنا وقت لگتا ہے، اور کون سا آپ کے سفر کے لیے موزوں ہے۔
Some Aussies try to fix the HEIC problem by renaming the file from .heic to .jpg in File Explorer. This does not work — the file's internal header is still HEIC, only the extension changed. Cambodia's validator scans the actual file bytes, not the filename, and the upload still fails. Always convert through a real tool that re-encodes the file.


The chemist-counter alternative
If all of this feels like more fiddling than it is worth, Aussie chemists, Officeworks, and Australia Post all offer in-store eVisa photo services that hand you a pre-validated JPEG plus printed copies for about $15 to $25 AUD. The file is correctly sized, JPEG-encoded, has no EXIF rotation flag, and is guaranteed to pass Cambodia's file-spec checks on first upload. Worth considering if your laptop and iPhone setup is making the conversion harder than it should be.
