Add Watermark places your text on every page of a PDF — once in the center or repeated across the page. Choose the color, opacity, size, and angle, and see a live preview on your first page before you apply it.
Arabic and other scripts are fully supported. The watermark is saved as a standard watermark object, and everything happens in your browser, so your document is never uploaded.
常见问题
Can I write the watermark in Arabic?
Yes. The text is rendered with your browser's fonts, so Arabic and other scripts are shaped correctly.
Can the watermark be repeated across the page?
Yes. Pick the “Repeated” layout to tile the text across every page, or “Once, centered” for a single stamp.
Can the watermark be removed later?
It's saved as a standard watermark object, so tools that understand watermarks — including TAMPDF's Remove Watermark — can remove it. It isn't a security feature.
Is my PDF uploaded anywhere?
No. The watermark is applied locally in your browser.
