Passport Photo Studio: ID Visa

Open the photo in My Photos, choose the 4×6 sheet and tap Save. Then order a standard 4×6 in (10×15 cm) print at any pharmacy, supermarket kiosk or online photo lab. Make sure “crop to fit” or borders are turned off. For home printing, use the A4 or Letter PDF and print at 100% (“Actual size”).

Use the Digital photo. It already has the official pixel size and file-size limit for your document.

Follow the tip shown next to the issue. Usually that means better lighting, standing a little further back, or keeping your head straight. You can fine-tune size and position with Adjust.

Purchased photos are listed in My Photos. If a purchase was interrupted, it's added the next time you open the app, and you'll see “1 unlock available” on your next photo; Settings → Purchases → Check for Missing Unlock looks for it right away. An unlock that was already used on a photo can't be restored, because each purchase makes one photo. For refunds, go to reportaproblem.apple.com.

Photos are checked against the official requirements, but the final decision is made by the issuing authority, and some offices have extra local rules. Check your authority's current guidance before you apply.
