Stamp a PDF
Drop in your PDF and the image together. The picture is placed on every page you choose at the size and position you set, with transparency preserved, so a PNG logo sits on the page rather than in a white box.
A PNG with transparency keeps its transparency, so a logo sits on the page rather than in a white box. Width is set as a fraction of the page, so the stamp lands the same relative size on every page size.
Select the PDF and the image at the same time — the PDF is recognised as the document and the image as the stamp.
Nine positions, from top-left to bottom-right, plus the centre. The margin controls how far it sits from the edge.
The width is set as a fraction of the page, so it scales correctly across differently sized pages. Opacity and rotation are adjustable.
Stamp everything, or just the cover, or just the signature page.
PNG alpha channels are embedded as-is, so a logo with a soft edge or a signature scanned onto transparent background composites onto the page properly instead of arriving in a white rectangle.
A stamp set to 25% of the page width lands the same relative size on A4, on Letter and on a landscape slide. Absolute point sizes would need re-tuning for each.
PDF can embed JPEG and PNG directly. WebP, GIF and BMP are decoded through a canvas and re-encoded as PNG first, so they work here even though the format cannot store them natively.
A calm, fast PDF workspace. Free to use, private by default.
