About Add watermark
Overlay text or an image watermark on every PDF page in your browser — nothing uploaded.
Drafts get marked CONFIDENTIAL. Agency proofs get a logo bug. Watermark stamps text or a PNG/JPEG across every page with opacity and rotation controls.
If both text and image are set, the image wins. Placement is centered in the current UI — enough for a diagonal draft mark, not a full imposition toolkit. For page indices use Page numbers; for running titles use Headers & footers.
Watermark is visible markup, not encryption. Encrypt PDF if you need a password gate.

Common questions
Can I put the watermark in a corner?
Not with a position picker today — overlay is centered. Rotate and opacity still help a diagonal draft mark.
Does watermarking remove underlying text?
No. It draws on top. Use Redact when content must not be recoverable as text.
Is the file uploaded?
No.

Why this one doesn't upload your file
