Watermark PDF

Add a custom watermark to your PDF directly in your browser — no uploads, no waiting, and no privacy concerns. Whether you need a visible “CONFIDENTIAL” stamp or a subtle branded watermark, this tool gives you full control over how your document appears.

You can apply either text or image watermarks across all pages instantly. Everything is processed locally, so your file never leaves your device.

Once watermarked, you can compress the PDF for easier sharing or merge PDFs into a final document.

Text watermarks are best for quick labeling — such as “Draft,” “Confidential,” or “Sample.” They are lightweight, easy to customize, and ideal for internal documents.

Image watermarks work better for branding. You can use logos or graphics to create a professional look across reports, invoices, or presentations.

Choose text for simplicity and speed, or image when visual identity matters.

This tool gives you precise control over how your watermark looks and behaves across pages.

• Adjust opacity to make watermarks subtle or bold
• Resize text or images based on document layout
• Rotate watermarks for diagonal or angled placement
• Choose exact position (center, corners, edges)
• Customize colors for text-based watermarks

This flexibility allows you to match different document styles without compromising readability.

You can preview your watermark in real time before applying it to the full document. This helps you fine-tune placement, size, and opacity without trial and error.

The preview updates instantly as you adjust settings, giving you confidence that the final output will look exactly as expected.

Watermarks are applied without degrading your document. Text clarity, images, and layout remain unchanged.

The tool overlays the watermark while preserving the original structure, ensuring professional results even for high-resolution documents.

Unlike many online tools, this watermark tool runs entirely in your browser using local processing.

• No file uploads
• No storage or tracking
• No external servers involved

This makes it ideal for sensitive documents where privacy is critical.

Watermarking is useful in many real-world scenarios where document control or branding is required.

You can label drafts before approval, protect intellectual property, add company branding to reports, or mark documents as confidential before sharing.

If you need to remove pages before watermarking, use the Split PDF tool to prepare your file first.

1. Upload your PDF — drag and drop or choose your file.

2. Select watermark type — text or image.

3. Customize settings — adjust size, opacity, rotation, and position.

4. Apply and download — get your watermarked PDF instantly.

After applying, you can also protect the PDF if you want to restrict editing or sharing.

This tool works across all modern devices without installation.

• Windows, macOS, Linux desktops
• Android and iPhone browsers
• Tablets and portable devices

You can watermark PDFs anytime, whether you’re working on a desktop or mobile device.

Because everything runs locally, watermarking is fast and consistent. There are no upload delays or processing queues.

Once your file is loaded, the entire process happens instantly — making it a reliable option for quick edits and repeated use.
