But if you want to convert JPEG to PDF file yourself, there are built-in Mac utilities at your service. For example, you can use the Preview app. Open your JPG file with Preview and head to the File menu. From there, select Export, and in the pop-up window, you'll see the Format field. Click on it and choose PDF. Of course, that’s a bit too many steps. With our free JPG to PDF converter, you’ll have your document ready much faster.
