Stamp text watermarks across selected PDF pages with custom font size, opacity and rotation angle. Watermarks are visual labels, not redaction or access protection.

Stamp selected pages

Use a single line of 1–80 printable Western Latin characters. Helvetica does not support every language or emoji; unsupported text fails explicitly. Choose font size, opacity and angle; text that does not fit is rejected rather than resized or clipped silently. Existing page rotation and crop bounds determine the visible placement.

The watermark is additional selectable text drawn over page content. It is not redaction, encryption or proof of ownership and can be removed by a capable PDF editor. Existing text/vectors are retained; review the downloaded pages. Rewriting can affect advanced PDF features or revision history, and universal PDF conformance is not promised.
