Free & Fast — No server uploads, no installs, no forced branding.
Protect your documents or brand your content by adding custom text or image watermarks. Adjust position, opacity, rotation, and more — your PDF is processed locally in your browser and never uploaded to our servers.
Adding watermarks to PDFs helps protect your documents, indicate draft status, or brand your content. This tool runs entirely in your browser — your files are never uploaded to any server, keeping your content completely private and secure.
Choose from text or image watermarks with full control over size, color, opacity, rotation, and positioning. You can even tile watermarks across the entire page for thorough coverage.
Is my PDF uploaded to a server?
No. All processing happens locally in your browser using JavaScript. Your files never leave your device.
What types of watermarks can I add?
You can add text watermarks with custom font size, color, and style, or upload your own image (PNG or JPG) as a watermark.
Can I tile the watermark across the entire page?
Yes! Select "Tile (Repeat)" from the Position dropdown to create a repeating pattern across your document.
Can I watermark multi-page PDFs?
Yes, the watermark is applied to every page of your document automatically.
