Everything About ID & Passport Photo Sizing
ID photo requirements differ by institution. Half-card 3×4cm is standard for resumes and certificates, while 3.5×4.5cm is used for passports, national IDs, and driver licenses in Korea. Online e-passport applications require the MOFA-recommended 413×531px digital format, and the US visa (DS-160) requires a square 600×600px JPEG. This tool provides these official specifications as presets for one-click accuracy.
The core feature is fixed-ratio cropping. Once you choose a preset, the crop box locks to that exact aspect ratio, so the photo never gets distorted. You can precisely extract the face area from a smartphone portrait and export it at the required pixel dimensions — with full support for both mouse and mobile touch dragging.
All processing runs locally via the browser's Canvas API. Sensitive photos containing faces are never uploaded to any server. Output is available as JPG (92% quality) or PNG, and filenames include the size specification (e.g., id-photo-3x4.jpg) so multiple formats stay organized.
Pro tip: passport photos require a plain white background. If your photo has a busy background, clean it up with a background remover first, then crop it to specification here — a fully at-home workflow for compliant photos. If a file size limit applies (e.g., 240KB for US visas), run the result through an image compressor.
