ID & Passport Photo Cropper

Crop a phone photo to Korean passport (35×45 mm), resident ID, driver's license, 3×4 cm, 5×7 cm, US passport/visa (2×2 in) or China visa sizes. Line the face up with per-size crown and chin guides, then save an exact-pixel JPG or a 4×6 in print sheet for any photo kiosk. Your photo is processed in the browser and never uploaded.

MOFA rule: 3.5×4.5 cm, head (crown to chin) 3.2–3.6 cm, taken within 6 months, white background, frontal, neutral. Output: 413×531px · on a 4×6 sheet: 8 copies

How to use

  1. Pick the size preset and resolution. For other sizes choose Custom and enter millimetres.
  2. Drop a photo or tap to choose one from your library.
  3. Drag to move and pinch (or wheel / zoom slider) to resize. Put the crown (excluding hair) on the red line, the chin inside the green band, and the nose on the blue centre line. Use Straighten if the head is tilted.
  4. "Save photo JPG" is for online submissions; "Save 4×6 print sheet" is for printing at 4×6 in at actual size, then cutting along the grey borders.

Korean passport photo rules in numbers

Korea's Ministry of Foreign Affairs requires a 3.5 × 4.5 cm colour photo of the upper body, facing forward, taken within the last 6 months. The most common reason for rejection is head size: the distance from the crown to the chin must be 3.2–3.6 cm. "Crown" means the top of the skull, not the top of the hair, so voluminous or tied-up hair may cross the red line. In this tool, if the crown sits on the red line and the chin falls inside the green band, the head size is within the rule. The background must be white and shadow-free, the face unobscured from forehead to chin, the expression neutral, and no tinted glasses, hats or heavy retouching.

Sizes at a glance

  • Korean passport, resident ID, driver's license: 3.5×4.5 cm — one crop works for all three.
  • 3×4 cm: resumes, job and exam applications, student IDs (no official head size; guides are a recommendation).
  • 5×7 cm: a larger photo showing more of the upper body.
  • US passport/visa: 2×2 in, head 1–1⅜ in (25–35 mm). Digital uploads (DS-160, online renewal) need a square image of at least 600×600 px — exactly what you get at 300 dpi here.
  • China visa: 33×48 mm, head 28–33 mm. Rules change; check the visa centre first.

Pixels, dpi and real size

Image files contain pixels, not centimetres. The dpi value decides the printed size: 3.5 cm is 1.378 in, so it is 413 px at 300 dpi or 827 px at 600 dpi. This tool saves exactly that many pixels and writes the dpi into the JPG, so word processors and "actual size" printing reproduce the official dimensions. Upscaling a small source only matches the pixel count while blurring the image, so you'll be warned when resolution is too low.

Doing it yourself instead of a studio

One 4×6 print holds eight 3.5×4.5 cm photos — enough for a passport, ID and visa. You do need to handle what the studio would: a white wall, even frontal light, and standing about a metre from the wall to avoid shadows. We deliberately do not offer AI background removal or face retouching, because passport rules forbid edits that change your appearance. Only areas the photo doesn't cover are filled with white, and you're warned when that happens.

Privacy — how your photo is handled

An ID photo is sensitive personal data. This page keeps it on your device: it is opened, cropped and saved inside your browser. Photo data, filenames and EXIF are not transmitted, and the saved JPG carries no location or camera metadata from the original. We log only an anonymous usage count, and closing the page discards the photo.

FAQ

Is my photo uploaded?

No. The photo is opened in your browser's memory, and cropping, resizing and JPG export all happen there. No photo data or filename is stored; the only thing we record is an anonymous "tool was used" count. Closing the page discards the photo.

Will the result be accepted for a passport?

The tool gets the size and head proportion right, but acceptance also depends on the photo itself — plain white background, no shadows or glare, facing the camera, taken within 6 months, no retouching — and the issuing office makes the final call. This tool does not replace backgrounds or retouch faces, so start with a well-lit photo against a white wall.

300 dpi or 600 dpi?

300 dpi is enough for prints and online forms: 35×45 mm becomes 413×531 px and 2×2 in becomes 600×600 px. Use 600 dpi for high-resolution lab prints or an archival master. You'll see a warning if your source photo doesn't have enough resolution.

How do I print the 4×6 sheet?

Print the sheet JPG at 4×6 in (10×15 cm) at a photo lab or kiosk with "fit to page" / auto-crop turned off so the physical size stays exact, then cut along the light grey borders. On a home printer, print at actual size (100%).

Tips for taking it with a phone?

Have someone shoot from 1.5–2 m away with 2× zoom. Close-up selfies use the wide lens, which enlarges the nose and distorts the face. Keep the camera at eye level and use even, frontal light rather than a single side window.
