1Upload PDF Document
Choose the document you want to stamp with a watermark.
2Design Watermark
Type text (e.g., CONFIDENTIAL, DRAFT) or upload a logo; adjust opacity, color, and angle.
3Set Placement & Patterns
Choose 9-point anchor grid placement, fine-tune X/Y offsets, or enable tiled mosaic mode.
4Stamp & Download
Apply the watermark across all pages or custom page ranges.

Watermark Type (Text / Image): Type custom security text or upload transparent PNG company logos.
Opacity Slider (5% - 100%): Controls the transparency level of the watermark.
Rotation Angle (-180° to +180°): Rotate watermark diagonally across the page (45° preset).
Tiled Matrix Pattern: Repeats the watermark diagonally across the entire page.

Tiled Mosaic Patterns
Cover the entire background with repeating security patterns.
Custom Opacity & Blending
Fine-tune transparency (5-100%) so text remains easily readable underneath.
Text & Logo Images
Support for high-resolution PNG logos and styled typography.
9-Point Anchor Placement
Align watermarks to corners, center, margins, or exact pixel coordinates.
Page Range Targeting
Apply watermarks to all pages, odd/even pages, or specific ranges.

Tiled Mosaic mode repeats your watermark text or logo at a 45° diagonal grid across the entire page, ensuring no single section of the document can be cropped or screenshotted without retaining the security identifier.

Yes! Toggle the layer position to "Under Content" (Background layer); the watermark will be drawn directly into the background stream before vector text and tables are rendered.
