Add Watermark to PDF

About Add Watermark to PDF

This tool adds watermarks to PDF files. You can add text watermarks or image watermarks (logos). Customize the position, opacity, rotation, and other properties. All processing happens in your browser for complete privacy.

What types of watermarks can I add?

You can add text watermarks (like CONFIDENTIAL, DRAFT, etc.) or image watermarks (logos, stamps). Text watermarks support customization of font size, color, opacity, and rotation.

Can I control watermark position?

Yes! You can place the watermark at Center, Top Left, Top Right, Bottom Left, or Bottom Right of each page.

What is opacity?

Opacity controls how transparent the watermark is. 100% is fully opaque, 50% is semi-transparent, and lower values make it more subtle.

Can I rotate the watermark?

Yes! You can rotate text watermarks to any angle (0-360 degrees). Common angles are 0° (horizontal), 45° (diagonal), or 90° (vertical).

What image formats are supported for watermarks?

You can use PNG, JPG, or GIF images as watermarks. PNG with transparency works best for logos.

Will the watermark appear on all pages?

Yes, the watermark will be applied to all pages in the PDF with the same settings.

Is my PDF file safe?

Absolutely! All watermark processing happens directly in your browser. Your PDF file is never uploaded to any server. Everything stays private on your device.

Can I preview before downloading?

Yes! You can preview the PDF with watermark before downloading to ensure it looks exactly how you want.
