How to add an image, logo or stamp to a PDF

Adding an image to a PDF can mean placing a logo, stamp, illustration or other visual element on an existing page. A clean result mainly depends on the correct page, placement and dimensions.

Add the image without rebuilding the whole PDF

With Add an image to a PDF, you keep the existing document and place the image on the selected page. There is no need to convert every page to images and rebuild the PDF.

Choose a suitable source image

A tiny logo may become blurry when enlarged, while an enormous photograph used as a small mark adds unnecessary weight. Choose dimensions appropriate to the intended display size. See Image resolution: pixels, dimensions and quality.

Check placement and background

Make sure the image does not cover text, page numbers or form fields. A photographed stamp may also include a white or grey rectangular background. A source with transparency can be preferable when the visual must sit over existing content.

Image or signature?

A scanned handwritten signature is technically an image, but its meaning deserves specific guidance. Use Add a signature to a PDF and read Add a signature to a PDF: what you need to know when signing is the actual goal.

Review the generated file

Check page, position, proportions and readability, and keep the original until the result is validated.

Key point

Use an appropriately sized source, place it directly on the correct PDF page, and verify that it does not hide important information.
