証明写真

証明写真 is listed on Google Play as a photography app. This SelfWander guide combines the linked listing with our practical decision criteria; it is not a hands-on performance test.

The publisher’s short description: “You can easily create ID photo data from photographs taken with a smartphone”. This describes the publisher’s positioning, not an independently measured result.

Working with your pictures

For 証明写真, our starting point is practical: try the app with a copy of an ordinary picture and inspect the saved output. Assess the whole workflow, including permissions, export quality and paid restrictions.

Image workflow

This is a topic raised by the Google Play listing for 証明写真. Test with a copy of one non-sensitive image. Look at the saved result, not only the preview, and check resolution, watermarks and export charges. Limit photo-library access when selecting a few files is sufficient.

Family use

This is a topic raised by the Google Play listing for 証明写真. An age label is only a starting point. Review chat, purchases, advertisements and parent controls before a child uses the product, then test whether the controls work on the account and device you intend to use.

What the evidence does—and does not—show

The figures shown here are a dated snapshot from Google Play, checked on 2026-10-22. The score reflects store-user ratings, not a SelfWander test score. The install band is a store figure and should not be read as current active users. Regional listings, prices, availability and ratings can change; consult the linked source before deciding.

Cost and permissions before installation

Check the current store price and any subscriptions or in-app purchases. A no-cost download does not mean that every feature or service is free. Read the publisher’s privacy disclosure and terms, and grant only the permissions needed for your intended use.

Our decision rule for 証明写真: continue only if the current listing matches your device and the task you want to complete. If a necessary feature, fee or support condition is unclear, resolve that on the publisher or store page before spending money or providing sensitive information.
