From time to time, you may need to add or remove portions of text found in a PDF file. Those using a PDF reader program, such as Adobe Reader, cannot type into a PDF file using those programs. Fortunately, purchasing an expensive PDF-editing software program is not the only option for those wishing to type into a PDF file. Downloading the proper software program will allow you to edit any PDF file on your computer and do so for free.
Download and install the software program Nitro PDF Professional (see Resources). You will be able to use this program to type into a PDF file even after the 14-day trial ends.
Open Nitro PDF Professional.
Click on the "N" icon that is located at the top of the software program.
Select "Open." Search for the PDF that you want to type into and then double-click that file to open it.
Click on the "Insert and Edit" tab. This is at the top of Nitro PDF.
Click the "Insert" button found under "Insert and Edit."
Scroll down through the PDF file until you find the spot that you want to type into and then click on that spot.
Enter the text in the spot you selected in the previous step.
Select a part of text on the PDF file you would like to edit. Once you've clicked on that text, a box will surround the text.
Right-click the box around the selected text and select "Edit Text." Once you do, you will be able to delete or add letters and words to that portion of text.
