About Peppol Invoice Viewer
ToolsWebPro Peppol Invoice Viewer is a free browser-based utility designed to open, inspect, and validate European electronic invoices formatted according to the EU EN 16931 standard. It provides native support for Peppol BIS Billing 3.0 (UBL 2.1), German XRechnung (both UN/CEFACT CII and UBL), and hybrid PDF/A-3 standards such as ZUGFeRD and Factur-X. As mandatory B2B e-invoicing takes effect across Europe — including Belgium's nationwide mandate starting 1 January 2026 and Germany's B2B reception mandate — small business owners and freelancers frequently receive machine-readable XML files without human-readable visual layouts. This tool parses the structured data, validates key compliance rules, presents a professional invoice layout in four European languages, and enables instant PDF printing without sending sensitive financial documents to external servers. If you need to create a visual PDF invoice from scratch, use our [Free Invoice Generator](/tools/free-invoice-generator).
ToolsWebPro provides this utility 100% free with no account creation. Our client-side tools run locally inside your browser memory so your uploaded files are never saved or transferred to third-party servers.

- How does Peppol Invoice Viewer work?
- Use Peppol Invoice Viewer directly in your browser without software installation or registration.
- Is Peppol Invoice Viewer safe to use?
- Yes. ToolsWebPro processes many tools client-side in your browser. We do not store your personal files on our servers for those tools.
- What is a Peppol e-invoice and why is it mandatory in Belgium in 2026?
- A Peppol e-invoice is a structured XML document conforming to the Peppol BIS Billing 3.0 and European EN 16931 standards. In Belgium, federal legislation makes B2B electronic invoicing via the Peppol network mandatory for all VAT-registered businesses from January 1, 2026, with strict non-compliance penalties applying after March 31, 2026.
- What formats does this e-invoice viewer support (UBL, XRechnung, ZUGFeRD)?
- The viewer supports all major European formats: Peppol BIS Billing 3.0 (UBL 2.1 Invoice and CreditNote), German XRechnung (both UN/CEFACT CrossIndustryInvoice and UBL), and hybrid PDF/A-3 invoices (ZUGFeRD 2.x and French Factur-X).
- How can I open and view an XML invoice file without installing software?
- Simply drag and drop your XML file into the viewer above. Our client-side parser reads the XML elements in your browser and displays a clean, human-readable commercial invoice complete with itemized lines, VAT calculations, and banking details.
- How do I view hybrid PDF invoices like ZUGFeRD or Factur-X?
- Drop the hybrid PDF directly into the tool. The viewer uses embedded PDF stream extraction to locate and decode the attached XML document (such as factur-x.xml or zugferd-invoice.xml) and renders both the structured invoice and validation status.
- Is my invoice data stored or sent to any server when using this viewer?
- No. All XML parsing, validation checks, and PDF exports are performed 100% locally in your web browser. Neither your company details, client data, nor financial amounts are ever uploaded to our servers or stored in any database.
- What is a Buyer Reference (Leitweg-ID) and why does the validator check it?
- Buyer Reference (BT-10) is a mandatory field under Peppol BIS 3.0 and German XRechnung. For public procurement in Germany, it contains the public entity's Leitweg-ID (routing code). Without it, automated routing fails and government invoice portals reject the document.
- How do I convert a Peppol or UBL XML invoice to a printable PDF?
- Once your XML invoice is loaded, click the 'Print / Save to PDF' button. The viewer applies optimized print styling (DIN A4 standard) and opens your browser's native print dialog, allowing you to save the formatted document as a high-quality PDF.
- Why does my XML invoice show a validation error for totals or tax breakdown?
- The validator verifies European EN 16931 business rules. Common causes include rounding discrepancies between individual line extensions and the net subtotal, mismatched VAT percentages and tax amounts, or a missing Buyer Reference.
- Can I open multiple e-invoices at once in batch mode?
- Yes. You can drag and drop multiple XML and PDF files at the same time or select multiple files. A tab bar appears above the invoice allowing you to quickly switch between documents, review their validation status, and print each one.
