Everything you need to know about our PDF watermarking service
Absolutely 100% secure! All processing happens entirely in your browser. Your files never leave your computer or get uploaded to any server. We use client-side JavaScript only, ensuring maximum privacy and security.
You can customize everything: text content, font size (10-80px), text color, opacity (10-100%), position (center, corners, diagonal), page selection (all, even, odd, custom ranges), and additional options like timestamps and page numbers.
No hard limits! The tool works entirely in your browser, so performance depends on your device's memory and processing power. We recommend files under 50MB for optimal performance, but you can process much larger files.
Yes! You can use the watermarked PDFs for personal, educational, and commercial projects without any restrictions or attribution requirements. The watermarked documents are yours to use as you see fit.
No, the original PDF quality is preserved. Watermarks are added as a separate transparent layer and don't degrade the original content quality. Images, text, and formatting remain exactly as in the original document.
