When using WPS PDF Insert Watermark on Windows, common questions usually involve unavailable buttons, effect removal, and scanned PDF editing, with 3 frequent answers below.
FAQ
Why is the Insert Watermark button grayed out?
- Make sure the file is opened in WPS as a PDF.
- Click Edit and enter Edit Content mode.
- Switch to Text Editing, then select the target text.
- 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?
- Select the text that already has the effect.
- Click the Watermark button on the toolbar.
- Confirm that the text returns to its previous appearance.
- Save the file so the change is not lost.
Why can’t some PDF text use the watermark effect directly?
- Check whether the content in the PDF is actually an image or a scanned page instead of editable text.
- If it is a scanned file, use OCR first to recognize the content as editable text.
- Enter Text Editing mode again and select the text.
- Then apply the Insert Watermark action.
