E-Invoice Tools
PDF to ZUGFeRD JavaScript Overview
PDF to ZUGFeRD JS module turns an ordinary PDF invoice into a compliant ZUGFeRD e-invoice in a single call. AI reads the invoice and extracts the complete EN 16931 data set - seller and buyer details, VAT identifiers, invoice lines, tax breakdown, payment terms, and monetary totals - then builds the Cross Industry Invoice (CII) XML and embeds it into a PDF/A-3 copy of your document. Scanned and photographed invoices work out of the box: pages without a text layer are read visually by the AI, so no separate OCR step is needed. The result is a hybrid electronic invoice that meets the German B2B e-invoicing requirements and opens in any ZUGFeRD 2.x capable system. Automate compliant e-invoice creation directly from your accounting, billing, or ERP workflow.

File
File Supported formats: .pdfFile to be converted. Value can be URL or file content.

AiMode
Collection Default: fastBalances conversion speed against extraction accuracy. Enhanced uses an advanced reasoning AI model that reads complex invoice layouts with enhanced accuracy. Fast responds quicker and suits simple, clearly structured invoices.
Values: enhanced fastReadMode
Collection Default: autoControls how PDF pages are read. Auto detects each page: pages with a text layer are read as exact text, scanned pages are read visually by the AI, so scanned and photographed invoices work without a separate OCR step. TextLayer trusts the embedded text only. Image renders every page as a picture, useful when the text layer is broken or incomplete.
Values: auto textLayer imageStoreFile
Bool Default: FalseWhen the StoreFile parameter is set to True, your converted file is written to ConvertAPI’s encrypted, temporary storage and made available via a time-limited secure download URL, valid for up to 3 hours. After this period, the file is permanently deleted.
When StoreFile is set to False, conversion happens entirely in-memory. The raw file bytes are streamed back in the API response without touching disk or external storage, ensuring maximum security and zero persistence so that only you can access the content.
