Watermark PDF
Stamp DRAFT, CONFIDENTIAL or your name across any PDF or image — diagonally, centered or tiled.
Documents going out for review need a watermark, not a lecture about desktop software. Type your text, pick diagonal, center or tiled layout, dial in the opacity and size, and download your stamped file in seconds.
Questions, answered
Does it work on images too, or just PDFs?
Both — PDFs and common image formats (JPG, PNG, WebP) can be watermarked.
What layouts are available?
Diagonal (corner to corner), centered (one large mark per page), and tiled (repeated across the page).
Can I make the watermark subtle?
Yes — the opacity slider goes from a faint 5% ghost to fully opaque, and you set the font size.
Is it free?
Yes — 10 documents free every month, no sign-up. Files are deleted after stamping.
