3 Ways to Edit PDF Files on a Mac
Below are three common ways to edit PDFs on Mac, along with step-by-step instructions for each:
#1. Using Preview (Built-In Mac Tool)
Every Mac has Preview pre-installed, and this app will let you carry out most basic PDF editing tasks. For example, you can add text boxes, highlight certain sentences, insert shapes, sign documents, and rearrange pages. Although it doesn’t allow full paragraph rewrites like a Word document, it works well for quick and practical edits.
Here is how you can edit a PDF with Mac’s Preview:
- Open Finder and locate your PDF file.
- Right-click on the file.
- Select Open with from the dropdown options.
- Click Preview to open it in the app.
Note: If Preview is already your default PDF viewer, double-clicking the file will open it automatically.
Follow these instructions to add text boxes to your PDF:
- Click Markup in the toolbar.
- Select the Text tool indicated as a text box with an 'A’ inside.
- Confirm that a text box has appeared on your PDF’s page.
- Click on it to drag it to the correct location.
- Type in your content.
- Resize the text box by dragging its corners if needed
- Adjust the font size, color, and alignment from the formatting bar.
If you want to review or mark up your PDF, these are the steps to take:
- Select the text that you want to modify.
- Click Highlight in the toolbar.
You can also insert shapes, arrows, or comments from the Markup menu, as this helps emphasize important sections or provide feedback.
The free Mac PDF editor will also let you apply signatures to documents, and you can do it in this way:
- Open Markup in the toolbar.
- Click the Signature tool.
- Create a signature using your trackpad, cursor, or connected stylus.
- Drag the inserted signature and resize it into position.
When you know how to sign PDFs on Mac, handling contracts, agreements, consent forms, or invoices becomes much easier.
For rearranging or removing pages, you can follow these instructions:
- Click View in the top menu.
- Press Thumbnails.
- Drag the pages to reorder them.
- Click Edit > Delete to remove a page.
This is useful when reorganizing study notes into a clearer order, removing unnecessary pages from a report, or adjusting the flow of a longer document before sharing or printing your PDF on a Mac.
#2. Using Online PDF Editors
Another way to edit PDFs on MacBooks and iMacs is by using online PDF editors, which sometimes offer more advanced editing features that can be accessed directly in your browser.
Depending on the platform, you may be able to:
- Remove or insert images
- Modify existing text instead of only adding text boxes
- Merge multiple PDFs into one file
- Compress large PDFs for easy sharing and storing
- Convert PDFs to Word, Excel, or other formats
One PDF platform lets you do all of the above, and it’s pdf.net. Our editor is fully browser-based, meaning you won’t need to install anything. As long as you have a reliable Internet connection, you can prepare and polish your PDFs on any device, including Macs.
Here is how you can access our full suite of tools to modify PDFs on Macs:
- Open your web browser.
- Go to pdf.net.
- Upload your PDF file by dragging and dropping it into the Drop file here to start box or selecting it from your Mac via the Choose file button.
- Wait for the document to load in the editor.
- Choose the tool you need at the top of the page: edit text, merge, split, sign, annotate, rearrange pages, or convert. You can also hover over More tools to find additional features.
- Make your changes directly within the document.
- Click Download in the top-right corner to save your PDF to storage.
Tip: If you want to share your PDF directly instead of downloading it and then sending it via email, you can use our Share PDF tool to generate a lightweight PDF link.
Besides the abovementioned tools, we have AI-powered features (Chat PDF, Summarize PDF, and Translate PDF) that help you improve the quality and clarity of the information inside documents without toggling between multiple tools.
Finally, apart from everything that makes it one of the best PDF editors for Mac, pdf.net also boasts an incredibly intuitive interface, so you won’t have to worry about overcoming any learning curves.
We use HTTPs connections, meeting the HTTPS-only standard to protect your information while it is being uploaded, processed, and downloaded. Unlike other online tools that hold onto your data, we delete yours shortly after you are finished with your file.
#3. Using Dedicated Desktop Solutions
Finally, you have the option to use dedicated desktop editors, usually built for full document modification. You can open a PDF in these applications directly from Finder:
- Install a PDF editing application on your Mac.
- Open Finder and locate the PDF file that you want to edit.
- Click and hold the file.
- Drag it onto the editor’s icon in the Dock or Applications folder.
- Release the file to open it inside the program.
Alternatively, you can right-click the PDF file, choose Open with, and select your preferred editor.
A PDF desktop editor might be handy if it is part of your team or company’s work processes. However, it might not be the best option when you only need to make small changes, such as highlighting, adding notes, or applying a signature.
They may also be less practical if you rarely edit PDFs and do not want to pay for a subscription, or if you are using a shared or restricted computer where installing software is not possible.
What You Can Edit or Modify in PDFs on Mac
Below are the most common actions you can take with PDFs on Mac:
#1. Add Annotations
Adding annotations means placing visual or written notes on top of a PDF without changing the original content. On a Mac, this includes highlighting text, underlining sections, and inserting comment boxes. These actions draw attention to parts of the text you want to remember, while comments let you attach notes or thoughts at precise locations.
Annotations are also helpful because they make information easier to process and organize. A study on digital annotation use shows that when users actively engage with text using highlights and notes, it supports deeper processing. It also helps with the integration of information across multiple documents, which is linked to improved learning performance.
#2. Insert Images or Shapes
Shapes such as arrows, rectangles, and circles allow you to direct attention to a precise area without rewriting the surrounding content. This keeps the PDF cleaner while still making the emphasis clear. As for images, you can insert logos, graphics, screenshots, or replacement visuals if part of the document needs correction or enhancement.
#3 Fill Forms and Add Signatures
Many PDFs are designed as interactive forms, allowing you to enter information directly into designated fields. This is helpful because it eliminates the need to print and manually complete documents. It also reduces errors that may occur when handwriting is unclear or when forms are scanned after completion.
Completing a fillable PDF form often includes adding an electronic signature, which is legally recognized under the ESIGN Act. Knowing how to sign PDFs on a Mac, therefore, allows you to complete NDAs, contracts, invoices, and other formal documents entirely in digital form without interrupting your workflow.
#4. Convert PDFs to Word, Excel, or Images
PDFs are designed to present documents in a fixed layout, independent of the software, operating system, or hardware used to create or view them. However, this stability makes deeper editing difficult. Converting a PDF into another format allows you to work with the content more flexibly.
- PDF to Word. You can directly edit paragraphs, adjust formatting, and restructure sections without placing text boxes over existing content.
- PDF to Excel. If the document contains tables, converting it to Excel makes it easier to sort data, run calculations, or reorganize structured information.
- PDF to images. Exporting a PDF as a PNG or JPG can be useful when you need to embed the content into presentations, websites, or other visual platforms.
#5. Merge, Split, or Compress PDFs
Merging allows you to combine multiple PDF files into one continuous file. Meanwhile, splitting lets you separate a large PDF into smaller files or extract specific pages. Compressing the file lowers storage requirements and makes sharing faster; together, these functions help you control how a document is organized and distributed.
3 Tips for Editing PDFs Professionally
Keep the following tips in mind when editing PDFs:
- Avoid placing text boxes on top of paragraphs. This can create alignment problems and become obvious when zooming or printing. Whenever possible, use tools (like pdf.net) that allow direct text editing so the content integrates naturally.
- Keep formatting consistent. When adding or modifying text, adjust the font type, size, spacing, and alignment to match the rest of the document. Even small inconsistencies can make the file look unpolished or uneven.
- Review each page carefully before finalizing. Minor edits can shift spacing, margins, or page breaks, so a complete scan helps ensure the structure remains intact. It helps to look at your PDF on different devices as well.

With pdf.net, you can edit text directly, insert images, merge or split files, compress documents, and convert PDFs to Word or Excel in just a few clicks.
