To edit a PDF document using this tool follow the steps below. Open PDF document. Open the program on your computer, click “Open File” to import the PDF file you want to edit. Note that this also applies for all other functions. Edit the text on the PDF. To access the edit mode, click on "Edit" and make the necessary changes.
