PDF/A Checker

Is your PDF really a PDF/A? The checker checks the key criteria directly in your browser and reliably flags violations. Not a full validation — but your file never leaves your machine.

Your file is processed entirely in your browser. No upload, no cloud processing, no network call.

We built this so you don't have to upload sensitive PDFs to a third-party service. A passed partial check is not a conformance proof — for full validation, use the veraPDF online demo.

Generate PDF/A automatically

In GrandTotal, dispatching an invoice automatically produces an audit-proof PDF/A — no extra steps. More on the format in the PDF/A article.
