Online Stamp Maker: How to Create a Professional Company Stamp

Make your company stamp or seal now. Round seals, dated stamps and approval marks, with a date that fills itself in and a serial number that never repeats. Free to design, and it goes straight onto a PDF, a Word file or an Excel sheet.

Start from one of these and change the wording, or start from nothing:

A good stamp does two jobs: it looks official, and it proves something. With an online stamp maker you can design a clean, professional seal in a few minutes, no software, no design skills, no trip to a print shop. Here is how to do it well, and how a digital stamp can be far more than a picture.

Pick a shape and a template

Start from a template, a round company seal, an oval professional stamp, a rectangular address or approval block, or a shield, hexagon or triangle for something distinctive. A standard round rubber seal is about 38mm; rectangular stamps auto-fit the number of lines you add.

Templates exist for almost every use: corporate and common seals, notary and commissioner stamps, bank and finance seals, medical and doctor stamps, government and education seals, approval marks like PAID, RECEIVED and APPROVED, and personal address or date stamps.

Add your ring text and centre lines

Curved text around the outer ring carries your company, office or seal name, top and bottom. The centre holds your main lines: a name, a date, a registration or serial number. Use placeholders like the date and serial tokens so they fill in automatically when the stamp is applied.

Each element can be restyled independently, font, weight, italics, underline, colour, and moved, scaled or rotated. Pick an ink colour from the classic rubber-stamp palette, or set any custom colour.

Drop in a logo, emblem or shape

Upload your own logo (PNG or SVG) or choose a built-in emblem, bank, government building, globe, shield, gear, anchor, crown, award, scales of justice, caduceus and more. Add stars, lines or geometric shapes as accents, and position each one exactly.

An optional aging slider adds a distressed, pressed-ink finish so the stamp reads like real ink on paper rather than a flat graphic.

Download, or make it verifiable

Export a high-resolution PNG (transparent for overlaying on documents, or on a white background), an SVG vector for print, or a PDF. Most stamp makers stop here.

A verifiable stamp goes further: save it to your library and each time you apply it to a document it can carry a locked serial number and a QR code anyone can scan to confirm it is genuine, see which document it belongs to, and check whether it has been revoked. A photographed rubber stamp can never offer that.

Apply it to a real document

Once saved, your stamp is available wherever you sign: upload a PDF, place the stamp and your signature, and download or send the sealed file. Inside a multi-party envelope you can build a stamp and apply it as part of the signing flow.

Questions people ask about this

How do I add a stamp to a Word document?

Drop the .docx in rather than exporting it. It is laid out exactly as written, headers, tables and letterhead intact, and the stamp goes on the page. No copy of Word is needed, which is what makes this work on a phone.

Can I add a stamp to an Excel spreadsheet?

Yes. The sheet is paginated using the workbook's own page setup, so the stamp lands on the printed page rather than floating over the grid where an inserted row would move it.

What marks can I make besides a company seal?

A PAID stamp, an APPROVED stamp, a RECEIVED stamp, a certified true copy stamp, and a date stamp that fills itself in. A DRAFT watermark or a CONFIDENTIAL watermark is a different job and can go on at the same time.

What PDF Verified is, and what it is not

A stamp identifies who issued a document. It is evidence rather than a formality that makes a document binding on its own, and it should only ever be made and applied for a business or an office you are authorised to act for: a mark that imitates another organisation in order to pass a document off as theirs is forgery in most places. Where a registry, a bank or a counterparty requires a particular form of seal, that requirement comes from them.

PDF Verified is a tool for preparing, signing, stamping and checking documents. It is not a law firm, a compliance service or a forensic examiner, and nothing here is legal, financial or compliance advice. Requirements differ by country, by document type and by the party asking, so check what applies to your document before you rely on it, and take advice where the document matters. You are responsible for the documents you create, sign and send, and for having the authority to do so: signing or stamping in somebody else name, or as an organisation you do not represent, is forgery whatever tool is used. To the extent the law allows, we accept no liability for how a document made with this tool is used or relied on. The full position is in our terms of service.
