Turns a selfie into a passport or ID photo checked against each country's official spec before you submit, processed entirely on your phone with nothing uploaded. Useful for avoiding a rejected application.
FreeNo sign-upWorks offline
What to know▼
How it works
Turns a selfie into a passport, visa or ID photo and validates it against each country's published official spec before submission, covering 35 document specs across 14 countries. Detection and processing run entirely on-device.

Pricing
Capture and validation are free; a watermark-free export is around $0.99 on mobile and $2.99 in the browser, per photo, no subscription.
Best for
