How It Works

Upload your target PDF document. Type your desired watermark text (e.g. 'CONFIDENTIAL DRAFT'), tweak the opacity slider and angle rotation dials for perfect placement, then click 'Apply & Download' to generate the stamped file.

Frequently Asked Questions

Will the watermark cover my original text? ▾

No, by default we apply an alpha-transparency (opacity) filter strictly to the watermark layer. This ensures the 'stamp' is clearly visible, while allowing all the original document text beneath it to remain perfectly legible.

Does the watermark get added to every page? ▾

Yes. The current rendering engine runs a fast loop, automatically calculating and applying the exact same watermark position coordinates onto every single page of your uploaded document.
