Can I watermark every page at once?

Yes. Your text stamp is applied to all pages in one pass, as a centered stamp or a tiled grid.

Can the watermark be removed later?

The watermark is written into the PDF content, so it cannot be toggled off - which is exactly what you want for document protection.

Does it work on scanned PDFs?

Yes. The stamp is drawn on top of any page content, scanned or digital.

Protect Documents with a Watermark

A visible watermark is the simplest way to mark a document as Confidential, Draft, or Do Not Distribute. AiLoveKit stamps your chosen text onto every page of the PDF with adjustable font size, opacity, and rotation - and it all happens locally in your browser, so the document being protected never gets exposed to a third-party server.

Watermark Options

Diagonal or straight - classic 45° stamps or horizontal labels.
Tiled layout - repeat the watermark across the page for stronger protection.
Opacity control - subtle enough to read through, visible enough to deter misuse.

For stronger protection, combine watermarking with Protect PDF encryption.
