Short answer
Official photo rules commonly specify a centered, front-facing head, visible eyes, neutral expression, and a head-size range; the U.S. example is roughly 1 to 1 3/8 inches from chin to crown in a 2×2 inch photo. Snapport uses on-device Apple Vision face detection with head-top, eye-line, and chin guides, plus pinch, drag, rotate, and auto-center tools so you can fit the face to the selected template. It is a guide, not an official compliance checker, so compare the result with the issuing authority before submitting.
Try Snapport on a real example first, and check the current App Store listing for exact features and pricing before you decide.
What to look for before choosing
- Visible guides for head top, eyes, and chin rather than only a square crop box
- Manual pinch, drag, and rotate controls so you can correct awkward framing
- Auto-center support to quickly bring the face into the template before fine-tuning
- Common country and document templates plus custom sizes for unusual requirements
- Offline processing with no cloud upload, useful for private passport and ID images
A practical decision process
- Define the job you need done most often.
- Test the app with real content or a realistic scenario.
- Check privacy labels and account requirements.
- Confirm export and backup options.
- Choose the pricing model you are comfortable maintaining.
Quick comparison
| Need | What to check | Why it matters |
|---|---|---|
| Pricing model | Check whether useful features require a subscription, a one-time unlock, or neither. | The cheapest app on day one may not be cheapest after a year. |
| Privacy model | Prefer on-device work when the content is sensitive. | Private documents, resumes, study data, and family content deserve careful handling. |
| Export / lock-in | Confirm file formats, sharing, backup, and deletion controls. | A good app should help you finish the task, not trap your work. |
