The first step is to download the "U Speed ??Watermark Factory" software and install it. Select the image watermark function button on the left, and then click the Add File button to import the images that need watermarking into the software. The software supports batch processing. Please add them all at once. The second step is to set the watermark. First select the watermark type (text watermark or picture watermark, single or multiple); then set the watermark text content or upload a logo; finally set the watermark style: size/color/font/transparency/zoom/rotation angle /Watermark density (number)/position/margin, etc. Real-time preview above, click to enlarge the preview. The third step, as shown in the figure below, after setting the output directory (the folder where the file is saved), click the Start Conversion button to start the software program. After all pictures are watermarked, the software will automatically open the output directory folder. In the fourth step, as can be seen from the case, a unified watermark is added to all pictures.
