Add Watermark to PDF

Ever shared a PDF and worried someone might copy it, misuse it, or claim it as their own? That’s where adding a watermark to PDF becomes your silent bodyguard. A watermark protects your content while promoting your brand at the same time at PDF House.

Choose placement (top, bottom, center, or anywhere else)

The best part? Everything you change will show instantly in the preview section in front of you.

Option 2 - Add Image Watermark

Prefer a logo instead of text?

Upload your image file. It could be:
