Add Watermark to PDF — Free, Customizable
Overview
Watermarks protect your documents from unauthorized use and identify drafts, confidential materials, or branded content. PDF Mavericks lets you add text or image watermarks to any PDF — choose font, size, color, opacity, and placement. All applied in your browser without uploading to any server.
How to Use This Tool
Upload your PDF on the Watermark page. Choose 'Text' to type a watermark like 'Confidential' or 'Draft', or 'Image' to upload a logo PNG. Adjust the opacity and position, preview the result, and download the watermarked PDF.

Can I add a logo as a watermark?
Yes. Upload a PNG file (transparent background works best) as your image watermark. Position it anywhere on the page with adjustable size and opacity.
Will the watermark cover the text in the PDF?
At lower opacity settings (20–40%), the watermark is visible but does not obscure the underlying content. For a strong 'Draft' watermark, use 50–70% opacity.
Can I remove the watermark after adding it?
This tool adds a baked-in watermark. To remove it, you would need the original unwatermarked PDF. Always keep a backup of the original.
