Digital seal maker for documents
A digital seal is the mark an organisation applies to show a document has been issued or certified by it, and in everyday use it means an image of a seal placed on a file, which is a different thing from the cryptographic eSeal that signs a PDF.

Every preview on this page carries a faint Estamplab watermark. Your own download does not: the editor renders your stamp again, clean, as a transparent PNG, an SVG or a PDF. See the full template library.
Two quite different things are called a digital seal, and conflating them wastes a lot of time. One is a picture: a round or embossed mark carrying an organisation name, applied to a certificate, a letter or a deed the way a wet seal or an embosser would be. The other is a cryptographic electronic seal, a certificate issued to a legal entity that signs a PDF and proves it has not been altered since. This page makes the first kind. If a counterparty is asking for an eSeal under eIDAS or an equivalent scheme, they are asking for the second, and no image file satisfies it.
What you get
- Round, oval and scalloped seal shapes, with the ring text curving to follow the rim the way a real seal is cut.
- An embossed look for certificates, where the mark reads as pressed into the paper rather than printed onto it, and a metallic foil finish for award and notarial seals.
- Ring text on the top and the bottom arc at once, which is how an organisation name and a jurisdiction sit on a real seal.
- A date and a reference number as live fields, so a digital seal applied to a certificate records when it was issued instead of showing the day the artwork was drawn.
- A transparent digital seal PNG, so the seal sits over the border or the text of a certificate rather than hiding it under a white square.
- The same design exports as SVG and PDF for print, so a seal used on screen and one sent to a printer are the same artwork at any size.
How to make it
- Open the stamp maker and pick a shape, or start from a template.
- Type your wording, then set the colour, border and size.
- Add the date, time, serial number or logo, and position each one.
- Preview it live, then download. Designing and previewing are free.
Questions
What is a digital seal?
In everyday use it is an image of a seal applied to a document to show the issuing organisation stands behind it. In the technical sense used by eIDAS and similar regimes, a digital seal or eSeal is a certificate issued to a legal entity that cryptographically signs the file. This tool makes the first. The two are not interchangeable and a supplier asking for one will not accept the other.
What is the difference between a digital seal and a digital stamp?
A stamp marks a document as it passes through a process: received, paid, approved, copied. A seal says the organisation issued or certified the document. The practical difference shows in the wording. A stamp carries an action and a date, a seal carries an entity name and the authority it is acting under.
Is a digital seal on a certificate legally valid?
That depends entirely on who is receiving it and under what rule. Some bodies accept an applied image, some require a cryptographic signature alongside it, and some still want an impression on the original. Check what the receiving authority asks for before relying on any seal, because the format they accept is set by them and not by the tool that drew it.
Can I make an embossed seal that looks pressed into the paper?
Yes. The emboss finish shades the artwork as relief rather than ink, which is what an embosser produces, and it is the right look for a certificate or a notarial seal. The foil finish does the same job for award seals, with a serrated or scalloped metal rim.
Can I put my organisation logo in the middle of the seal?
Yes, and the white background of an uploaded logo is removed automatically, so a crest scanned from a letterhead does not arrive as a white square inside the ring. Only use the seal of an organisation you are authorised to act for.
