Vietnam works in centimetres of its own, and the official e-visa portal spells its spec out exactly: a recent 4×6 cm portrait, JPG or JPEG under 2 MB, front-facing, no hat, no glasses, formal attire, white background — the portal auto-checks the image and blocks submission if it fails. The first preset renders 4×6 at 600 DPI (945×1417), double the 300 DPI minimum Vietnam's own photo standard demands. Paper applications use the same size physically: two newly-taken 4×6 prints, one glued to form NA1. Vietnamese passports match — 4×6 on white, head bare, both ears visible, no glasses, taken within the last six months by regulation.
The second preset is Vietnam's other standardized size, the 3×4 cm photo — the Ministry of Public Security publishes an official standard for it too (300 DPI minimum, face about 75% of the frame). One background trap worth knowing: passport and visa photos must be white, but the online driver's-license renewal officially wants its 3×4 on blue — so match the background to the procedure, because this tool won't recolour one. It resizes exactly and does nothing else, warning rather than silently stretching a face when the crop doesn't match. Everything runs on your device; an identity photo never touches a server here.

Frequently asked questions
What size photo does a Vietnam visa require?
4×6 cm — taller than the 35×45 mm most countries use. For the e-visa that means a JPG or JPEG under 2 MB at the 4:6 ratio (no pixel count is published; the preset's 945×1417 fits comfortably), front-facing with no hat or glasses, formal attire, white background. Paper applications want two newly-taken 4×6 prints.
What are the Vietnamese passport photo rules?
By regulation: 4×6 cm, taken within the last six months, looking straight ahead, head bare, both ears clearly visible, no glasses, formal attire, white background. Online passport applications upload the same portrait digitally at a minimum of 300 DPI, with the face filling about three-quarters of the frame.
What is a 3×4 photo in Vietnam?
The country's everyday document size, with its own official standard: 3:4 ratio, 300 DPI minimum, face about 75% of the frame. Watch the background — the generic standard is white, but the online driver's-license renewal officially requires blue, so shoot for the procedure you're actually doing.
Can this tool fix my photo's background?
No — it resizes exactly and does nothing else, and tells you so. Take the photo against the background your procedure names (white for passport and visa), then size it here. Nothing uploads anywhere: the resize happens entirely in your browser.
Is my file uploaded to a server?
No. ConvertUno runs entirely in your browser on your own device. Your file never leaves your computer or phone — there is no upload at all.
Is it really free, with no watermark?
Yes. Processing happens on your device, so serving you costs us almost nothing — no watermark, no account, no file-size limit, no daily quota.
