Add an official stamp to a PDF online
Add an official stamp to a PDF online without any software: design your stamp or company seal, download the transparent PNG or the SVG, and place it on the page in whatever PDF editor you already use. Each download can take a locked serial number, and the date and time can fill themselves in.
PDF Stamp templates, ready to edit
Open the stamp maker with any of these
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.
When to use PDF Stamp

- Approval and certified-copy marks
- Company seals on PDFs
- Official document stamping
How to make PDF Stamp
- Open the stamp maker and pick the PDF Stamp template, or type your own wording.
- Set the shape, colour and size, then drop in a logo and position the date or serial line.
- Download the PNG for everyday use, or the pack when the SVG and PDF are going to matter later.
How to put a pdf 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 pdf 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 pdf stamp be?
Decide the physical size before the pixel size. A pdf 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 pdf stamp does not prove
Whether a pdf stamp is required, optional or meaningless depends on the country and on the document. Many common-law jurisdictions stopped requiring a seal years ago while specific instruments still expect one. Check the rule for the place the organisation is registered, not the place the document is being sent.
Frequently asked questions
Is the pdf stamp free?
There is no charge to make a pdf 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 pdf stamp?
Yes. A date, a time, or both, positioned wherever they fit the pdf stamp. An empty date field means "whenever this is used", so the impression records the real day.
What format do I get?
You choose an image format for $1.50, or take everything zipped for $3.00. The pack is where the SVG and the PDF live, and where the Word version of the pdf stamp keeps its date as real text.
Is there a free maker, or only samples?
It is a pdf stamp maker rather than a pdf stamp template you download and then fight with in a word processor. Build a pdf stamp online from a pdf stamp sample, or start empty and use it as a pdf stamp generator: every part of the pdf stamp design stays adjustable. The pdf stamp price covers the file only, $1.50 for a transparent pdf stamp png or $3.00 for every format.
How do I add an official stamp to a PDF?
Design the stamp here, download the transparent PNG or the SVG, then place it on the page in whichever PDF editor you use. The transparent background means it sits over the text rather than covering it with a white box.
