Step 1: Download the "Watermark Factory" software first, then install and open it for use. Click the PDF Watermark function in the three functions on the left, and then import the PDF file that needs to be watermarked into the software. The software supports watermarking multiple pdf files at the same time, saving time.
Step 2, set the software at the lower right as shown in the figure below. Watermark type is "text watermark", single or multiple ("picture watermark" can also be selected); Enter the text content below and set the parameters such as text color/size/transparency/rotation angle/font/watermark position. You can preview the watermark style above the software, which is convenient for timely adjustment.
Step 3: After setting, click the Start Conversion button above to start the software program. After processing, the software will automatically open a folder where all PDF files with text watermarks will be saved.
The fourth step is to open a PDF file that has just been processed, and you can see that each page is uniformly added with watermark text, which is neat and standardized.
