Vietnam Visa Photo Requirements
The official e-visa spec: 4x6cm, under 2MB, no glasses. Not 35x45mm, and not the 1024KB limit third-party sites keep repeating.
Vietnam's e-visa photo is a 4 x 6cm image, in JPG or JPEG, under 2MB, on a white background, front-facing, with no hat and no glasses. That is the official requirement from the national e-visa portal, stated plainly and repeated throughout its instructions. Two details trip people up: 4 x 6cm is a taller, narrower shape than the 35 x 45mm most of the world uses, and the file limit is 2MB, not the 1024KB many sites claim.
This covers the photo for Vietnam's e-visa, the online route most tourists use. For how the same photo differs across countries, see passport photo size by country.
What size is a Vietnam visa photo?
4 x 6cm - a 2:3 shape, noticeably taller and narrower than 35 x 45mm. The Vietnam National e-Visa Portal specifies the physical size and the file limit, not a pixel count, so the 472 x 709 pixels this tool outputs is 4 x 6cm at 300 DPI rather than a number Vietnam has published. The point that matters: a 35 x 45mm photo is the wrong shape, and it will not simply crop down to fit.
It is 2MB, not 1024KB
You will find third-party sites stating the limit as 1024KB - that is, 1MB. The official instruction page says the photo must be "less than 2MB", and where a third-party figure and the issuing authority disagree, the authority wins. 2MB gives you more headroom than 1MB, so a good-quality 4 x 6cm photo fits easily.
The no-glasses rule is enforced
This one is not a suggestion. The portal lists "no glasses" alongside "no hat" and "formal attire" as part of the requirement, and the system validates your photo before you submit - it will reject one it considers invalid rather than let it through. Take the glasses off, wear formal clothing, face the camera squarely, and use a plain white background. The white background is a stated rule here, not a default, so get it right at the point you take the photo.
How to size it
The Vietnam visa photo maker crops your photo to the 4 x 6cm (2:3) shape and outputs 472 x 709 pixels, holding the file under the 2MB ceiling, on a white background - all in your browser, with nothing uploaded. It fills white behind a photo whose background has been removed, sets the shape and size, and compresses to fit. It cannot take your glasses off or judge your attire, so handle those before you photograph. To compare requirements across countries, the visa photo maker hub lists only those verified against their own issuing authority, including China, whose 33 x 48mm is different again.
FAQ
What size is a Vietnam visa photo?
4 x 6cm, JPG or JPEG, under 2MB, on a white background, per evisa.gov.vn. That is 472 x 709 pixels at 300 DPI. The portal states the physical size and file limit, not a pixel count.
Is the limit 2MB or 1024KB?
2MB. Vietnam's official instruction page says the photo must be "less than 2MB". The 1024KB figure circulating on third-party sites does not match the portal, and the portal is the authority.
Can I wear glasses?
No. The requirement is no hat, no glasses, formal attire, on a white background. The system validates your photo and will not let you submit one it considers invalid.
Is a 4 x 6cm photo the same as 35 x 45mm?
No. 4 x 6cm is a 2:3 shape and 35 x 45mm is 7:9. They look similar and are not interchangeable - use 4 x 6cm for a Vietnamese e-visa.
Is my photo uploaded anywhere?
No. The crop, resize and compression run in your browser using the Canvas API, so your photo never leaves your device.
