About Biometric
Biometric Photo Engine is an independent collection of browser-based photo tools. Its purpose is to make size conversion, print preparation and basic image checks available without sending portraits to an image processing server. The application does not require an account or maintain a customer photo database.
Editorial work consists of maintaining the document directory, comparing dimensions with linked references, describing limitations and correcting reported errors. Each document page identifies its source. Directory-derived entries are not presented as independently verified government rules. No government affiliation, named editorial board or professional accreditation is claimed.
For corrections, cite the document page and a current issuing-authority source. The source snapshot date describes when directory data was captured, not a promise that every requirement is still current.
