Add Custom Watermarks to PDF Online
Protect your documents or add professional branding with our powerful, browser-based watermarking tool.
Adding a watermark is the most effective way to protect your intellectual property and prevent unauthorized distribution. Whether you need to mark legal files as CONFIDENTIAL, tag a draft as DRAFT, or reinforce your brand by adding a company name, our tool gives you the precision you need.
🔐 Privacy Guarantee: Just like our other tools, all watermarking happens locally in your browser. Your sensitive files are never uploaded to our servers, keeping your data 100% private.
Protect Your Documents with Key Features
🎨 Opacity & Transparency
Fine-tune the transparency of your text to ensure it's visible enough to protect the file, but light enough to keep the document readable.
📐 Custom Rotation & Position
Rotate your watermark to any angle. Use the classic 45-degree diagonal for maximum security across the entire page.
💎 Secure Layering
Choose to place the watermark over or under the content. Stamping it under makes it more permanent and difficult to remove.
