One way to edit a PDF file for free is to use a free PDF editor. At one time or another you may need to edit a PDF but find you donât have access to a good editor. In this case, I recommend downloading a free trial version of a PDF editor. A good example here is PDFelement. Whether you want to prepare an academic or business document, write an eBook or even an article, this tool can help you make any changes you require without cost. To edit a PDF document using this tool follow the steps below. Open PDF document. Open the program on your computer, click âOpen Fileâ 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. Note that the text and font you edit will automatically match with the original text. Format and save your PDF. You can format your text by changing font color, size, text fit, spacing alignment through text edit mode. After you are satisfied with the edits, save and share the document.
