Everything You Need to Watermark a PDF
100% Private
Your PDF and any watermark image never leave your device. Everything runs locally in your browser.
Completely Free
No sign-up fees, no subscription. Free forever.
Text or Image
Stamp a text watermark with your own font size and color, or upload a logo/stamp image.
Full Control
Adjust opacity and rotation angle so the watermark is exactly as bold or subtle as you need.
Pick Your Pages
Watermark every page, or just a range like "1-3,5,8-end" — leave it blank for all pages.
Live Preview
See an approximation of your watermark on page 1 before you commit to the full PDF.
Friendly on Locked PDFs
Password-protected PDFs are detected up front with a clear message, not a confusing failure.
Real Cancel
Stop a watermarking run partway through a large PDF — it actually interrupts the page loop.
Works Everywhere
Desktop, tablet, or phone — no app required, works in any modern browser.
