ApowerPDF is a great PDF tool that allows users like me to edit PDF files on PC. But actually I also use it as my default PDF reader. If you also want to set this program as your default PDF viewer, you can follow the instructions below.

Although we can click “Open with” while opening a PDF file and use this to set ApowerPDF as the default PDF reader, here is a better solution:

1. Open a PDF file with ApowerPDF.

2. Go to “Help” on the tool bar and then choose “Set to Default PDF Reader”.

Next time, when you go to a PDF file, it will be opened with ApowerPDF.

More functions you can use in ApowerPDF:

Add or delete pages in PDF, crop one or more pages in PDF, add blank page into PDF, insert link, images, text in PDF, etc.
