FAQ Frequently Asked Questions

What watermarking features does the PDF Watermark Adder offer?

This tool supports both text and image watermarks with extensive customization options. Features include custom fonts, colors, sizes, rotation angles, opacity control, positioning (center, corners, diagonal, custom coordinates), repeat patterns, and batch processing for all pages. You can preview watermarks before applying and choose from preset templates for common use cases.

How do I add a watermark to my PDF?

Upload your PDF, then choose between text or image watermark. For text, enter your text and customize font, size, color, and opacity. For images, upload your logo or stamp. Position the watermark using preset locations or custom coordinates, adjust rotation if needed, then click "Apply Watermark". The tool shows a live preview before processing.

What image formats are supported for watermarks?

The tool supports PNG, JPG, JPEG, and SVG image formats for watermarks. PNG is recommended for logos with transparency. The tool automatically optimizes images for PDF embedding while maintaining quality. All image processing happens locally in your browser, ensuring your files remain private and secure.

Can I control the watermark transparency and position precisely?

Yes! You have complete control over watermark appearance. Adjust opacity from 0-100%, choose from 9 preset positions (corners, edges, center) or set custom X,Y coordinates. Rotate watermarks from 0-360 degrees, scale images to fit perfectly, and choose whether to apply to all pages or specific ranges. The live preview shows exactly how it will look.

Can I add multiple watermarks or repeat patterns?

Absolutely! You can add multiple watermarks by processing the same file multiple times with different settings. The repeat pattern feature allows tiling watermarks across the entire page for enhanced security. Choose from diagonal patterns, grid layouts, or custom spacing. Each watermark maintains its individual opacity and rotation settings.
