How does PDF to KSeF XML conversion work?

The converter uses artificial intelligence to read invoices in PDF format — whether they come from an accounting system, a scan, or a photo. The AI recognises the document structure and maps the data to the required schema.

The result is an XML file compliant with the KSeF FA(3) schema, which you can download and send directly to the National e-Invoicing System or import into an ERP system.

KSeF does not accept PDF invoices — only XML files compliant with the FA(3) schema are accepted.

Conversion is performed server-side by an AI model. Your data is not stored after the session ends.
