Short answer
Many printed ID photos are easiest to prepare at 300 DPI, where a 2×2 inch photo becomes 600×600 pixels and a 35×45mm photo is roughly 413×531 pixels. Snapport includes common templates and also lets you create custom sizes in mm, inches, or pixels at any DPI, then export JPEG, PNG, or PDF. It is ideal when your school, employer, visa portal, or local authority gives a specific size sheet, but you should still follow the portal's exact file-size and format limits.
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
- Support for mm, inch, pixel, and DPI input instead of only country presets
- JPEG export for most online forms, with PNG or PDF available when the receiving system allows it
- Face guides for head top, eye line, and chin so the crop is not only technically sized but visually compliant
- Offline, on-device editing so private ID photos are not uploaded to a web converter
- Pay-once pricing because technical resizing is a utility, not something that should need a monthly plan
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. |
