How do I add a watermark to a PDF for free?

Upload your PDF to PDFuck, type your watermark text, customize the appearance (size, color, opacity, rotation, position), then click Apply. The watermarked PDF is generated instantly in your browser — no account or payment needed.

Can I make the watermark semi-transparent?

Yes. You can adjust the watermark opacity from fully transparent to fully opaque. Semi-transparent watermarks are ideal for protecting documents while keeping the content clearly readable underneath.

Will the watermark appear on every page?

Yes. The watermark is applied uniformly to every page in the document, ensuring consistent protection throughout the entire PDF.

Can I add a CONFIDENTIAL or DRAFT watermark?

Absolutely. Common use cases include adding DRAFT, CONFIDENTIAL, SAMPLE, DO NOT COPY, or company name watermarks. You can enter any custom text and position it anywhere on the page.

Is my watermarked PDF private and secure?

Yes. PDFuck processes everything in your browser locally — your PDF is never uploaded to any server. This is especially important for confidential documents that need watermark protection without exposing the content to third parties.
