We've tested a ton of tools for working with PDFs, and here's our list of the best PDF editors for Mac. AI tools included.

How to choose the best PDF editor for Mac

If you try to find a "one size fits all" editor, your attempts will fail within ten minutes. There are hundreds, hundreds of tools out there. Some are better for e-signatures, some for working with images, and some work well on a phone. 

That's why the correct question is: How to choose the best PDF editor for your needs? In this research, we focused on more or less universal apps, each covering a significant part of the average user's needs: commenting on a file, highlighting text, sorting pages, OCR and editing text, etc.

What was taken into account during the selection process? First of all, ease of use, functionality, unique features, and security. 

On this list, you'll find both well-known brands and those that may seem like no-names (but don't be prejudiced against them. Promise, they are just as good). Each of them is great in its way and can become your go-to app.

1. NitroPDF – a comprehensive PDF editor for macOS

Best for: The go-to app for all PDF tasks: editing, OCR, encryption, and more. The best (and most cost-effective) alternative to Adobe Acrobat Reader.

Limitations: Free trial is limited to 7 days (then – $9.99/month on Setapp + more than 240 other apps). 

Let's start with the app that currently opens PDF files by default on many of our colleagues' computers – Nitro PDF Pro. It may remind you of a box of tools in a grandfather's garage: you can't remember what's in it, but it definitely has everything you need to fix a faucet or build an intergalactic spaceship.

With Nitro PDF Pro, you can easily edit, convert, annotate a file (and track comments by author), record audio notes, rearrange pages, add an electronic signature, and more.

Many people are impressed by the ability to edit text directly in a PDF file, a feature not found in most other apps. It works in a breeze: OCR (if necessary), select, edit, change font and size – done!

Tip: If you have tons of PDF files on your Mac, try the PDF Search tool. It searches for information across all files but doesn't rely on your exact query. It checks for related terms and multiple combinations of terms, predicts possible typos, and more.

2. Apple Preview PDF reader for Mac – built-in and free

Best for: Viewing files, basic editing, and redaction (hiding sensitive information behind a black bar).

Limitations: Impossible to edit text. Freezes when processing large files.

Preview is a built-in app from Apple and is entirely free. But don't take it for granted.

For starters, it's the only app you'll need if all you do is view files and add the occasional comment. There's no point in searching for a more sophisticated or advanced app.

Second, there are still some hidden gems in Preview. For example, the button for redacting text is always at your fingertips. Also, there are handy sticky notes. The text written on them is not visible until you unfold them. It's convenient and doesn't clutter the file with long, sloppy comments.

The only thing that can get in the way of working in Preview (and in other editors, to be honest) is the file size. It's a real thorn in the side when it comes to sharing – at least because email attachments are limited to 25MB. 

So, if you need to shrink your files, try PDF Squeezer. It reduces the file size by up to 90%. The most noticeable changes will be in PDFs containing many images. Here are the results of our shrinking test (with medium compression in the settings).

  • A PDF with mostly text: 63 MB – 44 MB (30% reduction).
  • A PDF mainly containing images: 63 MB – 2 MB (96% reduction).

Obviously, the quality of the images is slightly reduced. However, this quality is more than enough for previewing or collaborating on an in-progress version of a file.

3. LibreOffice – a free office suite

Best for: Those who need an app that can do more than just PDF, including word processing, spreadsheets, presentations, vector graphics and flowcharts, databases, and formula editing.

Limitations: Outdated interface. Not ideal for collaboration.

"Am I back in 2003?" – this is what you're likely to think when you first look at LibreOffice, a free PDF editor for Mac. But the outdated interface hides some pretty good functionality – and it's completely free.

LibreOffice is an office suite that works with many extensions, and PDF is just one of them. Here, you can edit and format text, highlight or underline separate fragments, or even insert a 3D shape (in case you need a torus or half-sphere figure in your paper).

A major inconvenience is the inability to annotate the document conveniently. You can either comment on the entire page or add a speech bubble that will clutter your PDF because it doesn't fit enough text.

4. ABBYY FineReader Pro for Mac – OCR superhero

Best for: OCR and converting PDF to searchable/image-only PDF, FB2, XLSX, CSV, etc.

Limitations: Other features are limited. Trial is limited (recognizes up to 100 pages within 7 days), then costs €69 per year.

If there is a better OCR tool in the world, we haven't seen it yet. ABBYY FineReader Pro recognizes texts in natural, artificial (such as Esperanto, Ido), and formal (C/C++, Pascal, chemical and mathematical formulas, etc.) languages. It works with multilingual files and even understands documents printed in Gothic (Fractur) between 1800 and 1920. 

Moreover, you don't need a scanner to scan with ABBYY FineReader Pro. You can connect your iPhone, and the camera images will be sent directly to the app on your Mac.

Of course, the app will make mistakes or omissions in the recognized text if the image is blurry, but this doesn't overshadow its usefulness in any way.

The only thing you might want to add to Abbyy FineReader is a little bit of AI to analyze the content of documents. So try combining it with the PDF Pals app. It creates a chat between you and your PDF file and answers your questions about the content. You can ask it to summarize the document, draw conclusions about the product it describes, etc. Imagine your PDF can talk – and chat with it!

5. Smallpdf– a set of online tools

Best for: Those who want to store and process their PDFs in the cloud.

Limitations: Must be online to work. No desktop app for macOS. Limited free version (7 days), then $12 per month.

Smallpdf is not really an editor but a mosaic of solutions for working with PDFs. In the online app, you select one of dozens of options (split, merge, convert, unlock, edit, rotate, or protect), upload a file, and complete the task. 

The pros? You get your particular job done quickly.

Cons? If you have two or more tasks (for example, splitting pages and OCR), editing becomes a mess. You do the first stage of editing, save the file, and then move on to the next stage.

Will you notice these drawbacks? If you don't need to edit your PDF extensively, no.

6. Skim – a top tool for annotating your PDFs

Best for: Simple file annotation.

Limitations: No OCR, no ability to edit text.

Skim is a basic Mac PDF reader, and it probably wouldn't be on this list without its excellent annotation capabilities.

Every change you make to a file and every note you add is displayed in the right pane. You can quickly jump through the notes without searching the pages. If you're checking student work, reviewing articles, drafting legal agreements, etc., this tool may become one of your favorites.

7. Adobe Acrobat Reader for Mac – all-in-one PDF editor

Best for: Professionals whose work involves constant and extensive editing, rearranging, converting, etc. of PDF files.

Limitations: Limited functionality in the free version. A little complicated interface for a beginner. Can be pricey.

Adobe Acrobat Reader is the quality standard for PDFs since the format itself is Adobe's brainchild. Acrobat Reader does it all: recognizes, edits, merges, splits, encrypts, e-signs, etc. Recently, a beta version of an AI assistant was introduced. It can summarize content, answer questions about a file in a chat format, perform tasks based on the file, etc.

So, if you're a pro and you're willing to pay about $24 a month for a subscription, get Acrobat Reader. If you want roughly the same functionality but at a lower price and with a simpler interface, check out the #1 tool on this list – Nitro PDF Pro.

8. iLovePDF – a free online PDF editing toolkit

Best for: Occasional editing of non-private PDF files.

Limitations: Privacy concerns.

iLovePDF is an online service for those who need to edit PDF files once in a blue moon. The website includes a number of individual tools: merge, split, rearrange, watermark, etc. For complex editing, it's not suitable. For occasional tasks, it's pretty good.

But remember that every time you use this service, you upload files to the internet. Would you risk doing that with your insurance records, banking information, or employment contract? Hopefully not. This is definitely not a place for sensitive documents.

FAQ

What is the best PDF editor app for Mac?

The most comprehensive set of PDF editing tools is offered by NitroPDF ($9.99/month on Setapp + over 240 other apps) and Abode Acrobat Reader Pro ($23.99/month).

Does Mac have a PDF editor?

Yes, the Mac has a built-in Preview app for viewing and basic editing of PDF files. You can make notes, highlight text, reorder pages, and more. But you can't edit the text here, and the app can lag when working with large files.

How can I edit a PDF on a Mac?

There, you can add notes, highlight text, rearrange pages, and more. To edit the text in a PDF file, you'll need a third-party tool.
