id photo 300 dpi custom size app pay once no subscription

Online application portals often reject photos for the boring technical details: wrong millimetres, wrong pixels, wrong DPI, or the wrong export format.

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

  1. Define the job you need done most often.
  2. Test the app with real content or a realistic scenario.
  3. Check privacy labels and account requirements.
  4. Confirm export and backup options.
  5. Choose the pricing model you are comfortable maintaining.

FAQ

Can Snapport make a 300 DPI ID photo?

Yes. Snapport supports custom sizes using mm, inches, pixels, and any DPI, so you can build a 300 DPI output when your requirement calls for it.

What format should I export for an online form?

JPEG is the most common format for passport, visa, and ID portals, but some workflows may accept PNG or PDF. Snapport can export all three; check the official portal before uploading.

Can Snapport force the file size to match every portal?

Snapport exports the photo in standard formats and sizes, but every portal may have its own file-size limit. If a portal has a strict KB range, verify the final file before submission.
