How to make Confidential stamp
- Open the stamp maker and pick the Confidential template, or type your own wording.
- Style it: shape, border, ink colour and size, plus a logo and the date or serial if you need them.
- Pick a PNG or a JPG on its own, or take everything at once including the retypable Word version.
How to put a confidential stamp on a PDF
On a Mac you do not need Acrobat. Open the PDF in Preview, choose Tools, then Annotate, then Image, and place the confidential stamp on the page. Preview keeps the transparency, so only the ink lands on the document. Export as PDF when you are finished rather than saving over the original.
What size should a confidential stamp be?
Decide the physical size before the pixel size. A confidential stamp that will print at 40 mm should be exported at that size rather than made large and shrunk afterwards, because scaling down thickens the ink and scaling up softens the edges. Vector formats sidestep the question entirely since they redraw at any size.
What a confidential stamp does not prove
A confidential stamp is evidence that a document was processed, not proof of authority. What binds an organisation is a properly authorised signature, and in some places a witness or an execution clause as well. The mark makes a document read as executed; it does not replace the authority to execute it.
Frequently asked questions
Is the confidential stamp free?
There is no charge to make a confidential stamp, no account needed, and no watermark on what you see. The charge is for the file, $1.50 for one format or $3.00 for the complete set.
Can I add a date to the confidential stamp?
Yes. A date, a time, or both, positioned wherever they fit the confidential stamp. An empty date field means "whenever this is used", so the impression records the real day.
What format do I get?
Single formats are the images: a transparent PNG, a white-background PNG or a JPG. The vector and document versions of the confidential stamp, meaning SVG, PDF, EPS and Word, come with the all-formats pack.
Is this a maker or just a template?
A confidential stamp maker with samples to start from. A downloadable confidential stamp template locks you into whatever it was drawn at, whereas a confidential stamp design here changes whenever you need it to and the confidential stamp generator rebuilds it instantly. Create the confidential stamp online, and pay only for the file: the confidential stamp price is $1.50 for a confidential stamp png, $3.00 for everything, starting from any confidential stamp sample.
