Edit your PDF in Adobe Acrobat

This way of editing different PDFs on Mac has several advantages. The main one is that it offers powerful tools to amend a PDF which makes polishing documents trouble-free.

There are a few downsides. The service can be costly, which might not fit every budget, and since it’s a third-party program, you need to spend time creating an account and installing the PDF editing software before you can start retouching.

Acrobat is awesome if you deal with PDFs a lot and need something that can handle just about anything. Yeah, it costs more than the free stuff, but if this extension is part of your daily work, it’s totally worth it.

Method 4. Microsoft Word

If you’re comfortable using MS Word, it is also possible to edit your PDF documents with it.

  4. Turn the updated document back into PDF using the Word to PDF free converter.

Edit PDF as a Word file

Microsoft Word can help you edit a PDF on all MacBook and Apple devices thanks to its familiar interface and compatibility with common formats. However, be cautious when improving your PDF that’s been converted to DOCX. Word may shift elements you didn’t intend to change, like images or tables.

Overall, this method allows you to make amendments, but transforming files can be time-consuming and sometimes tricky. Word works well for folks who just need to make small tweaks without learning new software. It’s a last resort when other options aren’t available.

Tips for editing PDFs on macOS

  • Enable OCR. If your PDF contains scanned images or text, use Optical Character Recognition (OCR) to turn it into flexible text. Many PDF/A editors offer this functionality.
  • Protect the original. Before making changes, create a backup of the PDF. This way, you can always revert to the previous version if something goes wrong.
  • Take advantage of annotations. PDF software programs and services let you add comments, highlights, sticky notes, and sketches. These tools are great for reviewing or marking up documents without correcting the main content.
  • Check compatibility. Make sure your edits don’t interfere with how the PDF will be utilized. For example, if you plan to share it digitally, verify that recipients can open and interact with the file properly.
  • Reduce size. If the PDF grows too large after altering, employ file optimization to make it easier to share and faster to load.
