ID & Passport Photo Sizes: Complete Online Guide

Updated June 16, 20265 min read

An ID photo is a standardized portrait with a plain background and fixed dimensions required for documents. An online AI ID photo maker removes the background, applies the correct size and background color, and lays out a print sheet — no studio visit needed.

Background color matters

Most IDs require white or light blue; some visas require off-white or red. Pick the exact color the document specifies before exporting — an AI maker lets you switch the background instantly after removing the original one.

Print vs digital

For printing, use 300 DPI and the layout sheet (e.g. multiple 1-inch photos on a 5-inch print). For online submission, follow the portal's pixel size and file-size limit, then compress if the file is too large.

Step-by-step

  1. 1

    Upload a clear headshot

    Use even lighting, a neutral expression, and shoulders visible against any background.

  2. 2

    Auto-remove background

    The AI cuts out the subject and lets you choose white, blue, or another required color.

  3. 3

    Pick the size

    Select 1-inch, 2-inch, passport, or a custom size in mm/px.

  4. 4

    Export & print

    Download the single photo or the print sheet at 300 DPI.

Yes — use the layout/print sheet option, typically several photos on a 5-inch print.

What if the file is too large to upload?

Compress the image to the portal's size limit while keeping the required pixel dimensions.
