Although extremely easy to read, PDF documents are quite tricky to deal with when you need to edit them. If, however, you have the best PDF editor for Mac, making changes to the PDF file shouldn’t be complicated. In this article, we will focus on showing you how to edit a PDF on Mac.

Solution 1: Edit PDF Documents on Mac Using Preview

1 Adding Content to the PDF File

If you would like to use a free PDF editor for Mac, Preview will be your best option. The Preview tool is available by default on macOS. The tool is as extensive as other PDF editors with the exception that it is incapable of editing the pre-existing text.

Its main benefit is that it does not require plugins or add-ins to enable editing – you will just need to open the file and start editing right away.

To learn how to edit a PDF on Mac using the Preview tool, you will need to follow the steps outlined below:

Step 1: Open the PDF document with Preview.

Step 2: Click View on the menu bar and then select the “Show Annotations Toolbar” (or “Markup Toolbar” if you are running Yosemite macOS or later).

Step 3: The fourth button from the right of the toolbar will allow you to add text to the document. Once you click the button, you can start typing new content to the PDF document.

Step 4: Most of the other editing tools offered by Preview will be available under Tools. To be able to strike through text, underline text, insert a note, etc. you will need to visit Tools > Annotate.


Preview is more ideal for filling forms since it does not modify already existing content. However, you can always draw a white box over the existing text to hide it and then write new content over the box. While this is not the best way to edit PDF files, it is the only option for changing the content you have on a PDF file using Preview.

2 Merging PDF Files

Above, we have shown you how to add content to a PDF document. In some instances, you may not want to add content but to merge several PDF files. This can be achieved quite easily via the Preview application. The steps below should show you how:
