Short answers to the questions we get most often.
Open your signed PDF in Adobe Acrobat Reader. A bar at the top shows that the document is signed. In the signature panel you can see that the signature is valid and that the document has not been changed since you signed. It is a qualified signature under the European eIDAS regulation: trust comes from the official EU trusted lists, and an embedded timestamp proves when you signed. That keeps the signature verifiable in the long term.
This is what a successful signature looks like in Adobe Acrobat Reader.
Don't want to rely on Adobe alone? The European Commission offers a free, official validation tool. Upload your signed PDF there to get an independent validation report.

Signing with an older eID card? The tool may show a note that "the organisation name is missing in the trusted certificate". That's normal and not an error: older cards chain to an older government root certificate that doesn't carry an organisation name. Your signature stays valid and qualified.
You need two free programs, plus a card reader and your eID:
Works in Google Chrome, Microsoft Edge, Firefox, Safari and most browsers.
For Safari (macOS) you also need the Safari extension — install it and enable it via Safari → Settings → Extensions.
Feel free to let us know through this short form. We read everything and use it to improve the tool.
After uploading, you choose the spot and page by dragging a signature box. The signed document shows a stamp there with your name, national register number and the date, derived from your eID certificate.
