There seems to be a lot of demand on the Internet. Now I have opened the software to see the PDF file and then add the watermark where you want to build it. The first one is the watermark effect in adobe reader, the other one is in the software.
Drag and Drop the mouse to the location where you want to stamp the file, but it does not support the encrypted PDF file. If you want to stamp it, you need to crack the encrypted PDF file to generate a new PDF file.
The software comes with the batch pdf to image conversion function, but does not support encrypted pdf files! The technology has been implemented and the architecture is being designed!
Supports adding text watermarks, but this is the design below.
Convert image, convert text, add image watermark, text watermark, set watermark image, set the font, I will have time to separate it and share it with you for free!
