To seal a document, simply click sealing on the left menu.
Next select the document you want to seal.
Optionally, you can add a reason for sealing which will appear in the sealing stamp.
Choose if you want to add a sealing stamp to every page (the default is to only stamp the first page - the technical seal still applies to the entire document)
Choose if you want to add long term archival support (this includes additional costs).
Click seal.
Download the document and store in a secure place.
