then press the Source File option, then select the picture you want to file the PDF file from your computer.
Then after waiting for a while the image will be uploaded then you will see an option called Ad Files. Press on that option.
By presenting this option you can set as many images as you want. When you set the whole image then you will see an option called Convert on the right side.
When you submit the convert option, you will see that you have to wait a bit. Your PDF file is automatically generated. When the PDF file is fully generated then you can download it if you want.
If you want, you can zip file from here, you can convert text, you can edit and you can download file by rotating it. Thank you.
