What this tool does
- Four layers checked: the PDF/A-3 container, the attachment and its relationship, the XML grammar, then the business rules of the European standard.
- Every error is named by its code (BR-CO-15, BR-E-10), located at the XML line, with what was found and what was expected.
- The profile trap is said out loud: MINIMUM and BASIC WL are valid Factur-X profiles that do NOT satisfy EN 16931, because they carry no invoice lines.
- As many invoices as you like, no account and no volume limit: there is no server to pay for behind it.
What it does not do: This is not a certification, and we are not an accredited platform: we issue no attestation. The report says "no error detected across the N rules tested", never "compliant invoice": full PDF/A validation needs veraPDF, which nothing matches in a browser.
Nothing is uploaded. Cut your network connection once this page has loaded: the tool keeps working. How to check it yourself.
The other tools
- Merge PDFs: Several files, one document, in the order you decide.
- Organize pages: Reorder, rotate, delete, duplicate: the whole plan.
- Extract pages: Pick pages, take them out into a document of their own.
- Delete pages: Remove pages while looking at them, and they do not survive under the file you get.
