Frequently asked questions
Are Chinese text watermarks supported?+
Yes. Choose local sans-serif, serif or monospace fonts and adjust weight and italic style. Text is drawn as a transparent image and embedded in the PDF without downloading a font file. Added watermarks cannot be selected as text, and font appearance varies by device.
Can I watermark only selected pages?+
Yes. Enter page numbers or ranges such as 1,3-5. Pages outside the selection will not receive a watermark.
Can I remove existing watermarks?+
This tool adds new watermarks. It does not detect or remove watermarks already in the original file.
