Embed your company logo or custom image on every page of your PDF. Control size, position, and transparency.
Adding your company logo to every page of a PDF reinforces brand identity and asserts ownership. Whether it's a subtle corner logo at 15% opacity or a prominent centered watermark, the image is permanently embedded in the document.
Use a PNG with transparent background for the cleanest result — the logo appears naturally on the document without any background box.
Protect your documents by adding text or image watermarks to all pages.

An image watermark embeds your logo, signature, or custom graphic on every page of the PDF. The image is stored as a shared XObject resource in the PDF and referenced by each page's content stream. It's permanent — visible in all PDF viewers and when printed. Transparency (opacity) control lets you choose between a subtle background mark and a prominent overlay.
Use cases include:
Adding a company logo to branded documents before distribution.
Embedding a signature image as a watermark on authorized documents.
Adding a 'Sample' or 'Draft' graphic stamp to documents.
Branding client-facing reports with a company logo.
Adding a copyright graphic to published PDFs.
Image watermarks are ideal for branding documents and asserting visual ownership.

Opacity is applied via the graphics state (ExtGState) — the image is drawn with the specified alpha value.
