Watermark Features
Full control over how your watermark looks
Text Watermarks
Add any text — "CONFIDENTIAL", "DRAFT", your company name, or custom text. Control font size, color, and style to match your brand.
Image / Logo Watermarks
Upload your company logo or any image as a watermark. PNG with transparent background gives the cleanest result.
Opacity & Rotation
Fine-tune opacity from 10% to 100% and rotate the watermark at any angle. Live preview updates as you adjust the settings.
Flexible Positioning
Place your watermark in the center (diagonal), tiled across the full page, or in any corner — top-left, bottom-right, and more.
All Pages
Apply to all pages, first page only, last page, or filter by odd/even pages. Pro users get per-page custom control for complex documents.
100% Private & Secure
Files are encrypted in transit, processed in isolated containers, and deleted within 24 hours. Your documents are never viewed or shared.
