Add Watermark to PDF

Add a watermark to one PDF or batch many at once. Pick text watermark (custom font, size, color, opacity, rotation angle) or image watermark (PNG / JPG, scale, opacity). Position: center diagonal, header, footer, corner. Apply to all pages or a specific range.

When to use this

Use for: branding documents you share externally (logo watermark on quotes / proposals), marking documents as DRAFT or CONFIDENTIAL, watermarking distributed PDFs to discourage unauthorized re-sharing, adding 'COPY' watermark to PDF copies of originals.

Frequently Asked Questions

Can I make the watermark transparent enough not to obscure content?

Yes - opacity adjustable from 0 to 100%. Most watermarks look good at 10-30% opacity (visible but not distracting). The preview pane shows you the actual rendered look before downloading.
