About This Tool
Add image watermarks to PDF documents with our free online logo watermarking tool. Overlay company logos, brand images, or custom graphics on all pages, creating branded documents compatible with Adobe Acrobat Reader and all PDF viewers.
Upload PNG, JPG, or other image files and position them as watermarks. Control size, placement, and opacity for subtle branding or prominent identification. PNG images with transparency produce the best results for professional overlays.
All image watermarking happens locally in your web browser. Your documents and logo files never upload to external servers, ensuring privacy for branded materials, proprietary documents, and files containing confidential company graphics.
Perfect for adding company logos to official documents, branding PDF reports and presentations, applying organizational seals to certificates, or watermarking documents with custom graphics. Works with all PDF files from Adobe Acrobat, Microsoft Office, and any PDF source.
