    How to Watermark and Secure PDFs

    Protecting your intellectual property is simple with our 'Watermark PDF' tool. Whether you're a photographer adding a logo to a portfolio or a lawyer marking a document as 'Confidential', our tool provides professional-grade results without leaving your browser. Start by uploading your PDF and choosing between a text-based or image-based watermark.

    You have total control over the appearance. Adjust the opacity to ensure the watermark is visible but doesn't block the underlying text. You can also rotate the watermark and choose its exact position—centered, in the corners, or tiled across the page. This flexibility ensures your branding remains consistent across different types of documentation.

    Because we use local processing, your 'Original' high-resolution files and your company logos never touch a third-party server. This is a massive security upgrade over cloud-based watermarkers, where your internal assets could potentially be indexed or stored. It's the safest way to brand sensitive corporate memos or creative drafts before they are shared with clients or the public.

    Once you've configured your settings, download your watermarked PDF instantly. You can process multiple files in sequence, ensuring your entire document library is consistently secured. It's an essential workflow for any professional who values document sovereignty and high-quality branding.
