How It Works

Turn a PDF invoice into a UBL invoice in three simple steps.

Step 1

Upload Your PDF Invoice

Drag and drop your existing PDF, DOCX, or XLSX invoice, or click to browse for it.

Step 2

AI Extraction and UBL Build

The engine extracts the invoice data, maps it to the EN 16931 model, and re-serialises it as a UBL 2.1 invoice, validated before download.

Step 3

Download and Review

Your UBL XML downloads instantly. Open it in the viewer and check the amounts before sending: extraction from an unusual layout can misread a figure.

Why Convert PDF to UBL?

Go straight from the invoice you already have to the UBL syntax that Peppol access points and a growing number of buyers expect.

AI Data Extraction

The converter reads your PDF, DOCX, or XLSX invoice and detects the seller, buyer, line items, tax rates, and totals, no manual re-keying.

Validated EN 16931 UBL

The extracted data is rebuilt as a UBL 2.1 invoice and checked against the EN 16931 business rules before you download it.

Peppol BIS Through the Review Step

The direct conversion writes EN 16931 UBL. For a Peppol customer, choose Convert with review: add both parties' Peppol addresses and download Peppol BIS Billing 3.0.

Private and Free

Your invoice is processed in-memory over TLS and never stored on our servers. No installs, no account to start.

Frequently Asked Questions

Everything you need to know about converting a PDF invoice into UBL.

Yes. A PDF carries no structured data, so the converter reads it the way a human would: AI extraction detects the parties, lines, rates, and totals, then rebuilds them as a UBL 2.1 invoice validated against EN 16931 before download.
Always. Mistakes can happen: an unusual layout or a low-quality scan can be misread, and the EN 16931 validation cannot catch a wrong but plausible figure. Open the result in the viewer and compare it with your PDF before sending.
The direct conversion writes EN 16931 UBL, the core European standard. A Peppol access point expects Peppol BIS Billing 3.0, which also needs the electronic addresses of both parties, rarely printed on a PDF. For a Peppol-ready file, choose Convert with review: the extracted data opens in the UBL generator, where you add the two Endpoint IDs and download Peppol BIS Billing 3.0.
Yes. Since 2026 Belgian VAT-registered businesses exchange structured invoices in Peppol BIS UBL, so Belgian customers expect UBL rather than a plain PDF. Choose Convert with review to add both Endpoint IDs (scheme 0208 and the enterprise number for a Belgian company) and download Peppol BIS Billing 3.0. How it reaches your customer (a Peppol access point, or the channel you agree with them) is a separate step.
No. If you hold the CII XML, or a Factur-X PDF that embeds it, use the CII to UBL converter instead: it is an exact field-by-field transposition of the same EN 16931 model, with no AI extraction involved.
Then there is nothing to convert: the UBL invoice generator builds the same EN 16931 UBL from a guided form, with the Peppol Endpoint IDs built in.
Yes. UBL is one of the three formats of the French socle, alongside Factur-X and CII, and the exchange network accepts an uploaded UBL invoice. Your French customers will usually still expect Factur-X or CII; UBL answers the partners who ask for it.

How the PDF to UBL conversion works

A PDF invoice, even a clean export from your accounting software, carries no structured data a machine can process. UBL (Universal Business Language) is the opposite: an XML syntax of the EN 16931 European invoice model, the one the Peppol network runs on. The converter above bridges the two in one step: AI extraction reads your PDF the way a human would, the data is mapped to the EN 16931 model, and the result is re-serialised as a UBL 2.1 invoice, validated against the business rules before you download it.

One honest rule comes with the AI step: always review the output. Validation proves the file is well-formed and consistent, but it cannot tell a correctly extracted total from a plausible misreading of an unusual layout. Open the result next to your PDF before sending it. Read the UBL file in the viewer →

Who asks for UBL, and why

The most common trigger is Belgian: since 2026, VAT-registered businesses in Belgium exchange structured invoices in Peppol BIS UBL over the Peppol network, so their accounts-payable systems are built around UBL and a plain PDF becomes the exception handled by hand. The same expectation is long established in the Netherlands and the Nordic countries, and some large buyers simply only ingest this one syntax.

In France, UBL is one of the three formats of the socle, alongside Factur-X and CII: a UBL invoice is legally a valid e-invoice, and the French exchange network accepts an uploaded UBL file. Your French customers will usually still expect Factur-X or CII; UBL is the answer for the partners who ask for it.

Prefer a field-by-field review? The converter has a mode for it

Brave Mode converts in one pass; Convert with review, the default, opens the uploaded invoice in the guided editor with every extracted field laid out. Verify, adjust, then download the UBL from there: nothing is generated until you have seen the data.

Already holding the XML (a CII file, or a Factur-X PDF that embeds it)? The CII to UBL converter is an exact transposition with no AI involved. And when you need a hybrid Factur-X PDF rather than UBL, the PDF to Factur-X converter is the route.
