How to brand documents with a logo watermark using AI Leave feedback

A logo watermark says where a document came from without anyone having to read a footer. add_image_watermark places it, and opacity decides whether the result is branding or a mess.

The commands and config snippets on this page are for the .NET build of the server — the only platform available today. Installation and client setup: MCP server for .NET. Other platforms will expose the same tools with their own launch command; everything else on this page applies unchanged.

Put logo.png on every page of report.pdf at 30% opacity.

Both the document and the logo are resolved by name from your storage folder, so keep the logo next to the documents — or in the folder you configured — and refer to it by file name.

• Opacity 0.2-0.4 — visible, still readable underneath. This is the range most people want.
• Opacity above 0.6 — the logo dominates; useful for a specimen or a sample marking, distracting for a document people must read.
• Rotation — 0 for a clean centred mark, -45 for the diagonal look that matches text watermarks.

Iterate in the conversation rather than guessing:

That is too strong — redo it at 0.2.

Each attempt writes a new file, so the original is never at risk; delete the rejected copies afterwards.

Brand and state the status:

Add the logo at 25% opacity, then add a CONFIDENTIAL text watermark to that result.

Two calls, chained on the produced file — the “to that result” is what keeps both marks.

• Use a transparent PNG where possible: a logo on a white rectangle will show that rectangle over the page.
• Images are targets too. Branding a set of product photos works exactly like branding a PDF.
• Marks can be removed later. Because the logo is applied as a watermark object, remove_watermarks can take it back off when the document is rebranded — one of the practical advantages over pasting a logo into the source file.
• Check the licence before a brand rollout. Evaluation-mode output is not distributable: get_license_status.
