Korean passport photos use the 35 mm × 45 mm standard with the face measuring 32 to 36 mm from crown to chin — measured excluding hair — on a uniform white background with no border. Korea is also one of the few countries where you still bring a print: passport offices don't photograph you at the counter, so in-person applications need exactly one printed 3.5×4.5 photo on real photo paper. The first preset renders it at 600 DPI (827×1063). For online renewal through Government24 the spec is exact and official: 413×531 pixels recommended (anything from 395–431 wide by 507–550 tall is accepted), JPG only, 500 KB or less — the second preset. Visa applications use the same 35×45 white-background format, and both passport and visa photos must be taken within six months.
Korea's rules reward reading the fine print: hair may not cover the eyebrows or the outline of the face (the both-ears rule was abolished back in 2018, whatever older pages say), glasses are allowed but any lens glare or frames touching the eyes get the photo rejected, and tinted lenses or colored contacts are banned outright. Most important for a tool like this one: Korea explicitly rejects photos whose background was digitally erased or whitened — which is exactly why this tool resizes and does nothing else. Shoot against a real white wall, then size it here; the passport office even runs a free online photo pre-check on passport.go.kr worth using before you pay the fee. Everything runs on your device; the photo never leaves it.

Frequently asked questions
What size is a Korean passport photo?
35×45 mm with the face 32 to 36 mm from crown (excluding hair) to chin, on a uniform white background with no border, printed on photo paper — plain paper prints are refused. Bring exactly one print for in-person applications; the counter doesn't photograph you. The print preset renders the size at 600 DPI.
What are the rules for the online passport photo upload?
Official and exact: 413×531 pixels recommended, with uploads accepted from 395–431 pixels wide by 507–550 tall, JPG format only, 500 KB or less, taken within six months. Ignore blogs claiming a 200 KB cap — the official figure is 500 KB. The passport site also offers a free pre-check of your photo before you submit; a rejected photo can void the fee, so use it.
Can I wear glasses in a Korean passport photo?
Yes, with conditions: no light reflecting off the lenses and the frame must not cover any part of the eyes. Tinted or colored lenses, sunglasses, and circle/colored contacts are banned. Hair must leave the eyebrows and face outline fully visible — but both ears no longer need to show; that rule ended in 2018.
Why can't I just edit my background white?
Because Korea explicitly rejects photos whose background was digitally erased or replaced — retouching of any kind is a listed rejection ground. Shoot against a real white wall in even light, then only resize. That's all this tool does, on your device, with nothing uploaded anywhere.
