FAQ

Why is the Insert Watermark button grayed out?

  1. Make sure the file is opened in WPS as a PDF.
  2. Click Edit and enter Edit Content mode.
  3. Switch to Text Editing, then select the target text.
  4. If the text still cannot be selected, check whether the PDF is a scanned file and run OCR first.

How do I remove an Insert Watermark effect that is already applied?

  1. Select the text that already has the effect.
  2. Click the Watermark button on the toolbar.
  3. Confirm that the text returns to its previous appearance.
  4. Save the file so the change is not lost.

Why can’t some PDF text use the watermark effect directly?

  1. Check whether the content in the PDF is actually an image or a scanned page instead of editable text.
  2. If it is a scanned file, use OCR first to recognize the content as editable text.
  3. Enter Text Editing mode again and select the text.
  4. Then apply the Insert Watermark action.
