Software tool used: high-speed picture format converter

Step 1: Before the formal stitching, friends need to open the software "U-speed picture format converter" to be used in the computer, download and install it, then open the software and select the picture stitching function in the software.

Step 2: Then click the Add File button and upload some pictures to the software tool. You can adjust the splicing order by dragging the pictures.

Step 3: First, choose the sorting method (horizontal, vertical and user-defined) according to the splicing requirements. We can also set the width, height, spacing, margins, rounded corners and background of the mosaic picture, and then preview it until it meets our own aesthetics.

Step 4: After adjusting the parameters of the mosaic picture, click the Start Conversion button to start the formal mosaic procedure. Of course, after the splicing is completed, users don't need to find their own pictures, and the software will automatically pop up and open the output folder where the spliced pictures are saved, so users can view them directly.

Step 5: Finally, we can see that the software successfully merged the four uploaded pictures into one according to our setup requirements, and the effect was not bad, and the pictures were successfully spliced.
