Checking a document typically takes 5 seconds, with longer multi-page documents taking up to 30 seconds. Our advanced AI processes multiple verification layers simultaneously (metadata, document structure, content streams, traces of known editors, suspicious elements, etc), providing comprehensive results almost instantly.

ZekerPDF can analyze any document in PDF format. We are 99% accurate with computer-generated documents such as bank statements, payslips, tax returns and invoices. Identity documents such as passports, driver's licences, national IDs and residence permits are checked from a clear photo or scan (JPG, PNG or HEIC/HEIF). For financial documents, send the original PDF rather than a scan or screenshot so the metadata stays intact.

When a document is flagged as high risk, you will receive a list of indicators with specific areas of concern, including any detected alterations, inconsistencies or signs of manipulation. Our system provides clear explanations and evidence to help you make informed decisions about document authenticity.

ZekerPDF detects modifications and inconsistencies in PDF documents regardless of their language or origin. In addition to risk indicators, it provides a separate Trusted indicator for known document types already verified in our system. We continually expand this coverage with new financial institutions, payroll providers and invoicing software. If you need support for documents specific to your country, please contact us.
