Drop your photo, get a 4×6-shaped JPEG under 2 MB — the evisa.gov.vn upload format. The 2:3 crop and the compression run in your browser; the photo never leaves your device.
Vietnam's official e-Visa portal (evisa.gov.vn, run by the Immigration Department of the Ministry of Public Security) states the photo requirement both in its application instructions and on the application form itself — the form's own wording: a photo “newly taken, photo size 4x6 cm, jpg, jpeg format, size <2MB, straight face, no hat, no glasses, formal clothes, white background”. This page is preset to that spec: drop your photo, PixFit crops it to the 4:6 (2:3 portrait) shape, keeps it under 2 MB, and gives you a JPEG the form accepts. If the framing matters — your full head should end up centered — drag the crop preview to position it and let this page handle the format.
The portal publishes the size in centimetres, not pixels: 4×6 cm is the classic Vietnamese ID-photo print shape, and as an upload rule it means a 2:3 portrait aspect ratio. No official pixel resolution exists, so sites quoting a specific mandatory resolution for the e-Visa photo are quoting something the official instructions don't say. The 800×1200 preset here is a suggestion, not a rule: it matches the official shape exactly and keeps plenty of pixels — which matters, because the portal's automated check can reject a portrait that “does not meet the required resolution” (its own rejection message). So don't shrink the photo to a few hundred pixels to save bytes you don't need to save; the 2 MB ceiling is generous. If your source photo is smaller than the preset, don't upscale — type a smaller 2:3 size (say 600x900) into Exact size instead. There's no minimum file size, so nothing needs padding.
Step 1 of the application uploads two images: your portrait and a photo of your passport's bio page. The form's rule for it, verbatim: “Only upload 1 passport data page, upload clear photos, no lost corners” — one page, all four corners in frame. The system verifies both images automatically: it reads your name, date of birth, nationality and passport number straight off the bio-page image to fill the form, it checks that the printed face photo on the page is detectable (“No face detected in the passport image” is a rejection), and the portal's own instructions state that if the passport image is invalid you cannot submit at all. So the bio-page shot matters as much as the portrait: photograph the full page flat, in even light, with no glare across the machine-readable zone, and check the auto-filled fields carefully — the portal holds you responsible for discrepancies. If the portal balks at a huge bio-page file, the same tool above will compress it without visible loss.
The application client carries a specific list of portrait rejections, worth knowing before you pay: no face detected; too many faces detected (crop companions out, don't just center yourself); “Portrait photo was captured from another source” — the system tries to catch photos of photos and screen re-shoots, so photograph yourself, not your old print or your phone screen; resolution too low; and “Face not looking straight” — head-on pose, not a three-quarter angle. Several of these are worded “your application may be rejected” rather than as a hard stop — and since the e-Visa fee (25 USD single entry, 50 USD multiple entry) is non-refundable if the visa is not granted, a warning you can technically click past is still money on the table. PixFit fixes shape and bytes; the pose, background, attire and recency are on you and the camera.
The pages ranking for this search add rules the portal doesn't state. One popular photo tool sells the Vietnam visa photo at “0 to 45 KB” — a byte cap that appears nowhere on the portal, is roughly 45× tighter than the real <2 MB rule, and pushes you toward exactly the over-compressed, low-resolution file the portal's own check flags. An agency guide presents “JPEG or PNG”, a “white or light gray” background and a “taken within the last 6 months” rule as official specifications — the portal's stated rule is jpg/jpeg, white, and “newly taken” with no month figure. (Honesty note in the other direction: one stale string inside the portal's own code says “≤ 10 MB”, and its file picker technically accepts PNG — but the rule printed on the form and the live size-check error both say 2 MB and jpg/jpeg, so that's what to aim for. A JPEG under 2 MB satisfies every version.) If the screen in front of you states different numbers, the portal wins — over resizer sites, and over this page too.
Two cautions. First: the only official application sites are evisa.gov.vn and thithucdientu.gov.vn — the portal's own FAQ warns about unofficial lookalike pages, and the space around it is crowded with agency sites styled to look official that charge several times the government fee for the same application. Type the address rather than clicking an ad, and treat any site asking more than the official fee as a broker. Second: a visa photo travels with your passport details, so it shouldn't detour through a resizer's server — PixFit re-encodes entirely in your browser, nothing is uploaded, and the re-encode strips EXIF metadata (including GPS) as a side effect. An iPhone HEIC can be dropped straight in. For other countries' formats, see the India e-Visa (square, a different shape entirely), New Zealand and US visa pages.
Spec sources: the portal's application instructions at evisa.gov.vn (read July 2026) and the wording and check messages of the live application form at evisa.gov.vn, as read 1 August 2026. These details change — if the upload screen disagrees, believe the portal.
