The best PDF editing software for Macs allow you to not only view PDFs but edit, annotate, convert and do pretty much anything you can with other document formats.
However, although some PDF editing tools offer one-time purchase versions, most require a subscription.
We’ve therefore tried some of the best free PDF editors for Macs of 2025.
In our research and tests, we found a limited number of free PDF editors that allow you to do basic editing, rotating, re-ordering, combining, converting and compressing PDFs without having to pay.

What We Looked For In These Free PDF Editors
You won’t get all the full functionality of a paid PDF app in a free PDF editing solution and you’ll find most of them are very limited in functionality.
However, we looked for free apps that could do at least the following:
- Read, create, edit, and organize PDFs
- Combine multiple PDFs into one document
- Convert PDFs to another format such as from PDF to Word for use in Microsoft Office
- Secure documents by encrypting or password protecting PDFs
Note that most free PDF editing tools usually do not support the following types of features unless you upgrade:
- Collaborate on and approve PDFs
- Digitize paper documents and perform OCR scans
- Compare PDFs and other documents in different formats
- Sign PDFs
- Automate digitization of files to go paperless and manage documents
- Create PDF forms that can be filled-in
With this in mind, here are the best free tools to edit PDFs on a Mac.
1. Adobe Acrobat Reader
Adobe Acrobat Reader is by far the most widely used free PDF Reader on both Mac and Windows PCs and it allows a certain amount of PDF editing for free on a Mac.
For filling in forms or editing text boxes Adobe Reader is fine. You can also annotate or highlight documents and add comments for review.
There are stamp tools for Approved, Confidential, Revised and Sign Here and you can also draw on documents with a pencil tool.
However, if you need more power than this, you’ll need to get Adobe Acrobat Pro which is the best PDF editing software for Macs on the market.
Although it’s subscription only, you can also buy Adobe Acrobat Pro as a one time purchase too.
You can download Adobe Reader for Mac for free.
Pros:
- Made by Adobe who invented PDF
- Lots of PDF editing features
- Includes stamping of documents
- Mac desktop app
- Very secure
Cons:
- Some features require subscription
- Nowhere near as powerful as Adobe Acrobat Pro
2. Preview
macOS Preview is a free tool in macOS which allows you to do basic PDF editing, signing and merging of PDF pages on a Mac.
Preview can add text in text boxes, fill in forms and change the size or font of text.
The latest versions of macOS Sonoma onwards also support OCR scanning in Preview.
Simply upload a photo of some text or a page from a magazine and Preview will automatically recognize the text.
To edit a PDF on a Mac for free using Preview, follow these instructions.

3. PDF Candy (Online)
The one thing that stands Candy out from the rest of the pack is that apart from some pretty comprehensive PDF editing tools, it also supports OCR scanning in the free version.
Normally, you only get OCR scanning in paid PDF editing software and while Candy can scan and extract text from a PDF, it won’t actually allow you to edit it in the document.
Instead, it extracts the text and exports it to a text, Word or RTF format document which you can then edit.
There are in fact 44 tools in PDF Candy that you can use for free including PDF editor, convertor and OCR scanner.
Other tools include rearranging pages, adding watermarks, password protecting PDF files, editing metadata in a PDF, splitting PDFs and extracting images.
One you’ve finished editing the PDF online with PDF Candy, you can download it onto your Mac’s desktop.
You can start using PDF Candy for free now.
Pros:
- Includes OCR scanning for free
- Nothing to download or install
- Lots of PDF tools
- Easy to use
Cons:
- OCR only for text dumps
- Editing tools are limited
- No desktop app
4. LibreOffice Draw
LibreOffice is a free alternative to Microsoft Office for Mac and allows you to open and edit PDFs for free.

You may find that the formatting gets messed-up when you open PDF files in LibreOffice Draw though with objects and text boxes in the wrong position.
LibreOffice Draw also allows you to create PDFs from scratch and convert Word documents to PDF.
LibreOffice is one of the more limited free PDF tools but it is a desktop app if you prefer something that doesn’t just work in a browser or store PDFs in the Cloud.

- Allows you to create PDFs
- Mac desktop app
