What’s Needed

Before we dive into the editing process, you will need a few things to get started. First, make sure you have a Mac computer with the Preview application installed. Preview is pre-installed on every Mac and is a versatile tool for viewing and editing various file formats, including PDFs. You will also need a PDF document that you want to edit. It can be an existing PDF file or a scanned document that you want to make changes to.

What Requires Your Focus?

When editing a PDF document in Preview, there are several aspects that require your attention. First, you need to familiarize yourself with the tools available in Preview for editing PDFs.

While Preview is a powerful tool, it may not have all the advanced features and capabilities of specialized PDF editing software. Lastly, it’s important to ensure that you have a backup copy of the original PDF document before making any edits, just in case something goes wrong.

Method 1. How to Add Annotations to a PDF via Preview

Before we jump into the steps, let’s first understand how annotations can enhance your PDF editing experience. Annotations are like virtual sticky notes that you can add to a PDF document to provide additional information, highlight important points, or mark up areas for later reference. Here’s how you can add annotations to a PDF using Preview on your Mac:

Step 1: Open the PDF document in Preview. Simply double-click on the PDF file or right-click and select "Open With" followed by "Preview" from the dropdown menu.

Step 2: Once the PDF is open in Preview, click on the "Markup" toolbar icon. It looks like a pencil within a square.

Step 3: Select the annotation tool you want to use from the toolbar. For example, you can choose the highlighter tool to highlight text, or the text tool to add comments.

Step 4: With your desired annotation tool selected, click and drag on the PDF document to create the annotation.

Step 5: Customize the appearance and properties of the annotation by selecting it and using the options available in the Markup toolbar.

Pros:

Method 2. How to Merge PDFs Using Preview

Merging multiple PDF files into a single document can be useful when you want to combine related materials, create a comprehensive report, or organize various documents into a single file. Here’s how you can merge PDFs using Preview:

Step 2: Click on the "View" menu, select "Thumbnails" to display the thumbnail view of the document.

Step 3: Drag and drop the second PDF file into the thumbnail sidebar on the left side of the Preview window. The pages from the second document will be added to the first one.

Step 4: Rearrange the pages by dragging and dropping them in the desired order in the thumbnail sidebar.

Step 5: Save the merged PDF document by clicking on "File" in the menu bar and selecting "Save."

The ability to edit text and images directly in a PDF document can be invaluable for making corrections, updating outdated information, or adding new content.

Why Can’t I Edit A PDF Document in Preview?

1. Protected PDF: Some PDF documents may have restrictions or password protection that prevent editing. Make sure you have the necessary permissions or password to edit the document.

Fix: If the PDF is protected, you need to obtain the password or remove the restrictions before editing. This can be done using specialized software or online tools.

2. Scanned PDF: Scanned PDF documents are essentially images and do not contain editable text by default. Preview cannot perform optical character recognition (OCR) to convert scanned text into editable text.

Fix: To edit scanned PDFs, you need to use OCR software to recognize and extract the text from the scanned images. Once the text is extracted, you can edit it using Preview or other PDF editing software.

3. Compatibility: Preview may not support certain PDF features or formats that were used to create the document. In such cases, you may encounter limitations or errors when attempting to edit the PDF in Preview.

Fix: Try using a dedicated PDF editing software that supports a wider range of features and formats. Alternatively, convert the PDF to a different format, make the necessary edits, and then convert it back to PDF.

Implications and Recommendations

While Preview provides basic PDF editing capabilities, there are limitations to consider. Here are three recommendations to enhance your PDF editing experience:

1. Dedicated PDF Editing Software: Consider investing in specialized PDF editing software if you frequently work with PDF documents. These tools offer advanced features and more comprehensive editing capabilities.

2. OCR Software: If you often deal with scanned PDFs or need to extract text from images, OCR software can be a valuable addition. OCR software converts scanned documents into editable text, making them easier to edit and work with.

3. Online PDF Editors: Explore online PDF editing tools as an alternative to Preview. Online editors provide a range of features and can be accessed from any device with an internet connection.
