There are several ways to write on a PDF, including:
- Using Adobe Acrobat Pro DC: This is a paid program that allows you to add text to a PDF, as well as edit existing text and use annotation tools like highlight, underline, strikethrough, freehand drawing and add comments. It is available for both Windows and Mac.
- Using Preview: Preview is a built-in application on macOS that allows you to write on a PDF using the annotation tools like highlight, underline, strikethrough, freehand drawing and add comments. Open the PDF in Preview, go to the “Tools” menu and select “Annotate.”
- Using a third-party PDF editor: There are several third-party PDF editors available for Mac, such as PDFelement, PDF Expert, and PDFpen, which provide the feature to write on a PDF.
- Using online PDF editor: There are several online editors available, such as Adobe Acrobat online, Smallpdf, or PDFescape, which allow you to write on a PDF.
- Using a stylus or digital pen: you can use a stylus or digital pen on a device with a touch screen (such as a tablet or smartphone) to write on a PDF in real-time.
all the above options will work with all the documents and some may alter the original layout, formatting or add watermarks.
It’s also worth noting that when you write on a PDF, the changes will be saved as annotations on top of the original PDF and will not change the original content, unless you have the right software or a specific function to edit the text directly on the pdf. It’s always good to have a backup of the original pdf before making any changes.
