How to Footnote a PDF File
By Brandon Getty
Adobe's PDF file format simplifies sharing text documents, spreadsheets, product catalogs and images with your colleagues and clients. When creating your document, it may be useful to include accompanying hyperlinks, statistics or reference information in the footer. You can add a footer to the document using several different programs, including Adobe Acrobat, Free PDF Tools and NitroPDF.
Using Adobe Acrobat
Download and install the free trial version of Adobe Acrobat XI (link in Resources).
Open Acrobat, click "File," and then click "Open." Browse to the location of your PDF file, and then double-click it to open it in Acrobat.
Click "Tools," select "Pages," and then click the drop-down menu "Header & Footer" from beneath the "Edit Page Design" heading.
Click the "Add Header and Footer" option from the drop-down menu. A dialog box with various header and footer editing tools appears. A live preview window at the bottom of the dialog box shows a preview of what the header or footer will look like on your document.
Enter your desired footer text into the Left, Center and Right fields. Customize the appearance of the text using the font face, color and size options at the top of the dialog box. Adjust the margin placement of the footer using the four fields at the top of the dialog box.
Review your work in the preview window, and then click "OK" once your footer looks correct. Click "File," followed by "Save" to save your work.
Using Free PDF Tools
Download and install Free PDF Tools (link in Resources). Free PDF Tools is free for personal or commercial use.
Open Free PDF Tools and select the "Add Header and Footer" button from the main interface.
Browse to the location of your PDF file, and then double-click it to open it in the program.
Check the "Add Footer" box, but leave the "Add Header" box blank. Check the "Add on First Page" and "Show Page Number" boxes. If you do not wish to show the document's page numbers, leave the "Show Page Number" box blank.
Type your desired footer text into the "Text before Page Number" and "Text after Page Number" fields. Adjust the font style, font size and margin spacing using the options near the bottom of the dialog box.
Click the "Save As..." button to save the footer onto your document.
Download and install the free trial version of NitroPDF (link in Resources).
Click "File," then "Open," and then browse to the location of your PDF file. Double-click the file to open it in the program.
Select the "Insert and Edit" tab from the top menu. From beneath the "Header & Footer" grouping, select "Header & Footer," and then "New Profile."
Select the "Add" button, and then choose the type of footer you wish to add -- text, image or hyperlink. Enter a profile name for the footer so that you can reuse the same footer on other documents, if needed.
Adjust the font face, size and color using the menu options. Alter the margin spacing until you achieve the desired look.
Click the "Save" button at the bottom of the window to save the footer to your PDF file.
