For more complex editing tasks, consider using dedicated PDF editing software. These applications offer a wider range of features and greater control over the document’s content and layout.
Here’s a comparison of some popular options:
| Software | Features | Price |

Choosing the right software depends on your specific needs and budget.
Using Online PDF Editors: A Web-Based Approach
Another option for how to make changes to a PDF on a Mac is using online PDF editors. These platforms offer a convenient way to edit PDFs without installing any software.
Examples of online PDF editors include:
- Smallpdf: Offers a variety of tools for editing, converting, merging, and splitting PDFs.
- iLovePDF: Provides a range of PDF editing tools, including merging, splitting, compressing, and converting.
- Sejda PDF Editor: Allows you to edit text, add images, and annotate PDFs online.
While convenient, be mindful of security considerations when uploading sensitive documents to online platforms. Always review the platform’s privacy policy and terms of service before using it.
OCR (Optical Character Recognition): Editing Scanned PDFs
Many PDFs are created from scanned documents, which are essentially images of text. To edit these PDFs, you need to use Optical Character Recognition (OCR) software. OCR converts the image of text into editable text.
Here’s the general process:
- Open the PDF in an OCR-enabled application: Examples include Adobe Acrobat Pro DC, PDFpenPro, and FineReader PDF.
- Run OCR: The software will analyze the image and identify the text.
- Correct any errors: OCR isn’t perfect, so you may need to manually correct any misidentified characters.
- Edit the text: Once the OCR process is complete, you can edit the text as you would in a regular PDF.
The accuracy of OCR depends on the quality of the original scan and the sophistication of the OCR software.
Common Mistakes and How to Avoid Them
When learning how to make changes to a PDF on a Mac, it’s easy to make mistakes. Here are some common pitfalls and how to avoid them:
- Editing a flattened PDF without OCR: Attempting to edit a scanned PDF directly without OCR will not work. Ensure you perform OCR first.
- Choosing the wrong editing tool: Selecting the incorrect tool for the task can lead to frustration. Understand the capabilities of each tool before using it.
- Forgetting to save the changes: Always save your changes after editing to avoid losing your work.
- Compromising security: Be cautious when using online PDF editors, especially for sensitive documents. Ensure the platform has a strong privacy policy.
- Overlooking formatting inconsistencies: When editing text, pay attention to font styles, sizes, and spacing to maintain a consistent look.
By being aware of these potential pitfalls, you can avoid frustration and ensure a smooth PDF editing experience.
Exporting and Saving Options: Preserving Your Edits
After editing your PDF, it’s crucial to save and export it correctly to preserve your changes and ensure compatibility. Most PDF editors offer various saving options, including:
- Saving as a PDF: This is the standard option and preserves the original format.
- Saving as a flattened PDF: This option combines all layers into a single layer, making the document smaller but less editable.
- Exporting to other formats: You can export the PDF to formats such as Word, Excel, or image files.
- Saving with reduced file size: This option compresses the PDF to make it smaller, which is useful for sharing and emailing.
Choose the saving option that best suits your needs and ensures that your edits are preserved and the document is compatible with the intended recipient’s software.

Consider investing in dedicated software if you frequently work with PDFs and require advanced editing capabilities.
How do I redact sensitive information from a PDF?
Redaction is a feature available in some PDF editing software that allows you to permanently remove sensitive information from a document. Use this feature carefully, as redacted information cannot be recovered. Adobe Acrobat Pro DC and PDFpenPro offer redaction tools.
Can I convert a PDF to a Word document on my Mac?
Yes, you can convert a PDF to a Word document using Preview or dedicated PDF editing software. In Preview, go to “File” > “Export,” and choose “Microsoft Word (.docx)” as the format. Be aware that formatting may not be perfectly preserved during the conversion.
