Then, select PDF from the list and click on the Create button. Next, you will need to provide some information about the file. In the Name field, enter a name for your pdf file. In the Type field, you can choose either PDF or JPEG. In the Size field, you can choose either a small or large file size. Finally, in the Format field, you can choose either PDF or PostScript. Once you have provided all of these information, click on the OK button and then click on the OK button again to close Photoshop. You will now have a new pdf file created!
