Watermarking Features
Apply to All Pages by Default
Every marker is automatically applied to the entire document. Toggle "Apply to all pages" off to restrict a marker to a single page.
Multi-Layer Markers
Stack multiple watermarks — for example, a "DRAFT" text layer and a company logo layer — each with independent opacity and rotation.
Text Watermarks
Stamp any custom text (CONFIDENTIAL, DRAFT, SAMPLE…) with adjustable font size, colour, opacity, and rotation angle.
Image & Logo Watermarks
Upload a PNG or JPG (including transparent PNGs) and position it as a watermark. Control the display width as a percentage of the page.
Drag-to-Position
Visually drag each marker to the exact position you want on the canvas — or enter precise X / Y coordinates for pixel-perfect placement.
Duplicate Markers
Duplicate any marker to quickly create variations with the same style — ideal for adding the same text at multiple positions or angles.
Your PDFs Never Leave Your Device
Unlike most online watermark tools, everything runs entirely in your browser. Your confidential documents are never uploaded to any server or transmitted over the internet.
