Tip for Transparent Backgrounds: For the most professional result, use an image with a transparent background (such as a PNG file) so the stamp seamlessly blends with the document text rather than covering it up with a white box.

Frequently Asked Questions

What image formats are supported for custom PDF stamps in WPS?

WPS PDF supports common image formats for custom stamps, including JPEG, PNG, and BMP. We recommend using PNG files with transparent backgrounds to prevent the stamp from hiding the underlying document text.

Can I resize the approval stamp after placing it on the PDF?

Yes, once you have placed the stamp on the document, simply click on it to select it. You can then click and drag the corner handles to resize the stamp to fit your document perfectly.

How do I delete a custom stamp I no longer need?

To delete a custom stamp, go to the Comment tab, click the Stamp icon, and open the Custom Stamps list. Find the stamp you wish to remove, hover over it, and click the 'x' or delete icon next to it.

Will the imported stamp be saved for future PDFs?

Yes, when you create a custom stamp in WPS Office, it is saved in your Custom Stamps library. You can quickly access it from the Stamp menu and apply it to any future PDF documents you open.
