Portable Document Format (PDF) is a common and easy way to share electronic documents. To edit a PDF, you will need a PDF writing program with text recognition and editing features. While many comprehensive PDF writing programs are fee-based, there are shareware versions available. You can change the content of a PDF, such as font size, by following these steps:

Open the document you want to change. Click on the “Document” drop-down menu and select "OCR Text Recognition." Click once on "Recognize Text Using OCR," which will launch a separate window asking you to identify the pages of the PDF that should be recognized. Choose “All pages,” “Current page" or "From page." ("From page" will allow you to select a range of pages; example: pages 3 to 10). Click "OK." Depending on the number of pages you selected, the process could take some time.

Click on "Tools" and select "Advanced Editing" after the text recognition process finshes. Select "TouchUp Text Tool." Highlight the text you want to change.

Right-click on the highlighted text and select “Properties.” Select the “Text” tab on the “TouchUp Properties” pop-up window. Click on “Font Size” to select the desired font size. Click "Close."

Save the PDF using the “Save” option under the “File” drop-down menu. To maintain the source document, use “Save As” to rename the edited PDF. This will keep your original document in tact and create a copy of your edited document under a new file name of your choosing.
