Add Image to PDF
Place a logo, stamp or signature image on PDF pages at any size and opacity.
About this tool
Choose a PDF and an image. Pick a corner or click the preview of page 1 to place it, set the width as a percentage of the page, the opacity and a margin, choose which pages, and download. A transparent PNG keeps its transparency, so logos and signatures sit cleanly on the page.
Putting pictures on existing PDFs
Common jobs: a company logo in the corner of every page of a supplier's quote, a ‘PAID’ or ‘RECEIVED’ stamp on an invoice, a scanned signature on the last page of a letter, a QR code linking to an online version, a photo on an application form. Placing the image relative to the page — a percentage of its width, a margin from a corner — means it lands in the same spot on A4 and Letter pages alike. For a signature, cut the background out first with the background remover so it does not cover the line as a white box. Honest notes: the image is drawn on top of the page, so it can hide what is underneath; and pasting a signature image is an electronic signature, which is fine for most everyday documents but not the same as a certificate-based digital signature (Electronic vs digital signatures: what each is, and what a drawn signature on a PDF proves). The PDF sign tool draws a signature by hand, the watermark tool adds text across pages, and the QR code generator makes the code to place.
Frequently asked questions
Can I add the image to only one page?
Yes — choose first page, last page, or a range such as 1,3-5. The default is every page.
Will a PNG keep its transparent background?
Yes. Transparent areas of a PNG stay transparent on the PDF page. JPGs have no transparency, so they appear as a rectangle.
How do I put it in an exact spot?
Choose ‘Click on the preview’ and click where the centre of the image should go on page 1; the same relative position is used on the other pages.
Is my PDF uploaded?
No. The PDF and image are combined in your browser with pdf-lib and saved straight to your device.
