PNG/SVG is recommended (not mandatory). Transparent images usually look best.

Placement preview — first page

This places the stamp at a fixed corner/margin automatically — it doesn't support dragging it to an exact spot. For that level of precision, a desktop PDF editor is a better fit.

Place a signature image, logo or other stamp image on PDF pages. The tool provides separate PDF and image selection steps so you can choose the document first and then select the stamp or signature graphic.

What is a PDF signature stamp?

A signature stamp places an image file onto a PDF page. A transparent PNG or SVG signature can work well when you want the background of the page to remain visible around the signature.

How to add a signature image to a PDF

  1. Select the PDF you want to stamp.
  2. Select the stamp or signature image.
  3. Review the image preview and placement preview.
  4. Apply the stamp and download the updated PDF.

Useful for signatures, logos and seals

The same workflow can be used for a signature graphic, company logo, approval mark, seal or other image-based stamp. Prepare the image with a clean background or transparency when appropriate.

Check placement before exporting

Signatures and stamps should not cover important text, dates or form fields. Use the preview to confirm the placement before creating the final document.

Which image format is recommended?

PNG or SVG is recommended by the tool interface, especially when transparency is useful.

Can I use a company logo instead of a signature?

Yes. The stamp workflow can place an image, so a logo or seal can be used where appropriate.

Can I preview the selected stamp?

Yes. The current interface includes a selected-image preview and placement preview.
