How to Edit a PDF on Mac - From Preview to Dedicated PDF Editor

Part 1: Why Editing a PDF on Mac Feels Harder Than Word

PDFs (Portable Document Format) are fundamentally fixed-layout files. Text, images, fonts, and formatting are all locked into an unchangeable page. This means that directly editing a PDF is not as simple as changing a sentence in Word.

macOS's built-in Preview works mainly on an annotation layer, not the actual content. Many users report on Apple forums: "Preview can only annotate or add text boxes; it cannot truly delete or change words". Others note that in Dark Mode, annotation colors can be hard to see, and sometimes highlights or comments fail to save properly.

For Mac users, PDF editing has always been tricky. Preview handles basic annotations and signatures but cannot modify original text or process scanned documents with OCR. That's why many people look for more powerful PDF editors for Mac or online solutions.

When choosing a PDF editor, Mac users generally have three options:

• Free built-in tools: Preview for annotations, signatures, and minor text edits
• Professional desktop software: Full text/image editing, OCR, format conversion, and batch processing
• Online PDF tools: Quick, occasional edits without installing software

Part 2: How to Edit a PDF Document on Mac Using Preview

Preview is the built-in PDF tool on every Mac. While its features are limited, it's perfect for light editing tasks like annotations, signatures, or minor text additions.

Key Tools in Preview for Editing PDFs

• Annotation tools: Highlight, underline, strikethrough, and add shapes such as lines, rectangles, and circles
• Text and comments: Insert text boxes and add notes
• Signatures and forms: Add signatures via Trackpad, Camera, or iPhone/iPad, and fill existing form fields
• Page management: Extract, split, merge, or reorder pages
• Other features: Export files, view thumbnails, rotate pages

✏️ Steps to Edit a PDF on Mac Preview

• Open the PDF: Locate your PDF file in Finder. Double-click it to open in Preview, or select the file and press the spacebar to open Quick Look. Click the pencil icon to access editing tools.
• Access the Editing Tools: If the Markup Toolbar isn't visible, click the Markup Toolbar button (a toolbox or pencil-in-circle icon) at the top of the Preview window to reveal all editing options.

• Use the Editing Tools:
  • Add Text: Click the Text Tool icon (an "A" in a square), then click where you want to add text. Adjust font, size, and color from the toolbar.
  • Annotate and Highlight: Use the highlighter or drawing tools to mark up text or add notes.
  • Add Shapes and Signatures: Insert shapes like rectangles, circles, or arrows, and create or add signatures directly on the page.
  • Crop Pages: Remove unwanted sections using the crop tool.

• Save Your Changes: After editing, go to File > Save to update the original PDF. To keep the original, select File > Export and save a new version with a different name or location.

Quick Verdict:

It is best for basic PDF edits, like adding text, shapes, and signatures, but it struggles with complex text editing and advanced formatting. For simple annotations and free-hand markup, Preview is excellent.

Part 3: How to Edit a PDF on Mac Using Dedicated Software

When you need to truly edit a PDF on Mac - not just annotate or add text boxes, but modify text, images, tables, or even work with scanned documents - dedicated PDF software is the most effective choice.

1. Adobe Acrobat (Enterprise Standard)

Adobe Acrobat is the industry-standard PDF editor, offering powerful features suitable for enterprise or complex document tasks.

💡 Hands-On Experience

I tested Adobe Acrobat on a 30-page contract, editing clauses, inserting the company logo, and updating table data. The process was smooth, and the PDF's formatting remained intact. Text, images, and tables could all be precisely edited.

Key Features:

• Direct text and image editing: Edit content directly without overlays.
• OCR for scanned documents: Convert scans into editable text.
• Annotations and markup: Highlight, underline, comment, and sign.

✏️ Steps to Edit a PDF Document on Mac via Adobe Acrobat

  • Text: Click any paragraph or block of text. A blue border will appear, allowing you to type, delete, or highlight text. Adjust fonts, styles, and sizes from the Format menu.
  • Images: Select an image to move, resize, or replace it. To add a new image, click Add Image and position it as needed.
  • Pages: Rearrange pages by dragging them in the page thumbnail view or delete unwanted pages.
  • Other Tools: Use advanced options like adding watermarks, links, headers, footers, or performing other edits.

• Save Your Changes: Once your edits are complete, go to File > Save to update the original PDF, or choose File > Save As to create a new copy.

How to Edit a PDF Without Adobe: Top Alternative Ways

Quick Verdict:

Adobe Acrobat is ideal for advanced PDF editing, including text, images, forms, and OCR for scanned documents, with strong collaboration features. However, it can be expensive, somewhat complex for simple edits, and occasionally affect formatting in complex layouts.

Unlike heavy enterprise suites, Tenorshare PDNob focuses on practical features such as direct text editing, scanned document conversion, and quick exports, making it ideal for everyday work.

💡 Hands-On Experience

When testing it on a scanned invoice, OCR quickly converted the image into editable text with accurate formatting.

Quick Verdict:

It is best for basic to intermediate PDF editing tasks, such as OCR, annotating, page management (organizing, splitting, rotating), and converting PDFs to other formats like Word or Excel.

Frequently Asked Questions

Q1: How to directly edit text in a PDF on Mac?

To edit text directly, you need a professional PDF editor. PDNob PDF Editor and Adobe Acrobat allow you to modify the content layer, change fonts, update images, and even edit scanned PDFs with OCR. Preview can only overlay text, not change the original content.

Q2: Can I edit scanned PDFs on a Mac?

Yes, but you need OCR (Optical Character Recognition). Tools like PDNob PDF Editor and Adobe Acrobat can recognize text in scanned documents, making it editable. Preview does not support OCR.

Q3: How do I preserve PDF formatting when editing on Mac?

Always use a professional editor for content-layer changes. Preview may distort formatting for complex edits. When using online tools, check your PDF after downloading. Exporting as PDF/A helps maintain layout integrity.

Q4: Can I batch edit PDFs on Mac?

Batch processing is supported by PDNob PDF Editor and Adobe Acrobat, allowing multiple files to be edited, converted, or OCR-processed simultaneously. Preview and online tools generally lack this feature.

How do I ensure the original formatting is maintained after editing?

Use dedicated PDF editors like Adobe Acrobat or PDNob PDF Editor, which preserve formatting better during OCR conversion.
