How to Modify Font Properties of the Text in a PDF
This wikiHow teaches you how to change a PDF's font. You can do this by using the paid version of Adobe Acrobat, or you can use an online service called PDFescape to white out and replace text if you don't have the paid version of Adobe Acrobat.
Part 1Using Adobe Acrobat
1The Adobe Acrobat Reader app that many people have can open PDFs, but not edit them. In order to edit PDFs, you must have Adobe Acrobat Pro. You can also download a free trial of Adobe Acrobat from to temporarily use these features for free.
2If Adobe Acrobat is your computer's default PDF reader, just double-click the PDF that you want to open. If Adobe Acrobat isn't your computer's default PDF reader, open Adobe Acrobat, click File, click Open..., select your PDF, and click Open.
3It's a tab in the upper-left side of the Adobe Acrobat window.
4This pink icon is near the top of the Tools tab. Doing so will open a sidebar to the right of the PDF.
5Find the text that you want to edit, then click and drag your mouse across the text to select it.
6Using the tools on the right side of the window, you can change the following properties: Font - Click the drop-down box below "FORMAT", then click the font that you want to use. Size - Click the drop-down box with a number in it, then click a larger or smaller number. You can also type in a number to create a custom size. Color - Click the colored box to the right of the numbered box, then click a new color.
