What is the best pdf editor software on mac?

My recommendation: Start with Preview for 90% of needs, add Skim for heavy annotation work. This trifecta covers most editing needs completely free and locally on your Mac.

To edit PDF files on mac, you can use Firefox's built-in annotation tools to add comments, highlights, or drawings as a form of basic markup. Here's how you can do that without PDF editor for Mac:

1. Open the PDF in Firefox:

Drag and drop your PDF file into a Firefox window or right-click the PDF file and choose “Open with Firefox.”

2. Access the PDF toolbar:

Once open, you'll see a toolbar at the top of the PDF viewer with icons like highlight, draw, comment, etc.

3. Annotate the PDF:

Click on the highlight icon to highlight text.

Use the draw tool to add freehand markings.

Add comments or text boxes where needed.

4. Save your annotated PDF:

After making annotations, click the download/save icon (typically a downward arrow) to save the marked-up PDF to your Mac.

These annotations are not full edits; they are overlays or comments.To make actual content edits (changing text, images, or layout), you'll need a dedicated PDF editor for Mac or use online tools.
