PDF Unlimited, the free PDF editor for Mac
Acrobat, minus the acrobatics.
Read, mark up, sign, merge, compress and redact PDFs on your Mac. No subscription. No sign-in. No watermark. Free, forever.
Free forever. For macOS 14 or later, on Apple silicon and Intel.
It just reads. Pick a mode up top to start making a mess.
Exhibit A
Agreement to Stop Paying for PDF Software
This agreement is made between You (the Reader) and every PDF you will ever open (the Documents). It takes effect immediately, because it costs nothing.
1. Fees. The Reader shall pay nothing. Not monthly, not annually, and not “just this once to unlock Pro.”
2. Accounts. No sign-in shall be required to open a file the Reader already owns. Imagine that.
3. Watermarks. None. The Documents leave exactly as they arrived, plus whatever the Reader adds.
4. Privacy. The Documents stay on the Reader’s Mac. There is no cloud. There is only the Mac.
5. Confidential. The Reader’s banking PIN is 4071 and the Wi‑Fi password is the cat’s name, twice.

Open anything.
Contracts, scans, 900-page manuals. It’s built on Apple’s own PDF engine, so it opens fast and scrolls like butter.
- Open anything. Contracts, scans, 900-page manuals. It’s built on Apple’s own PDF engine, so it opens fast and scrolls like butter.
- Spread it out. Switch to Pages and your whole document lays itself out, every page at a glance.
- Reorder. Drag a page to where it belongs. Everything else politely moves over.
- Rotate. Someone scanned page three sideways. Someone always does. One click.
- Delete. “This page intentionally left blank.” Not anymore.
- Merge. Drop another PDF onto the grid. Now it’s one PDF. That’s the whole feature.
- Compress. Shrink it until your email stops complaining. Choose Low, Medium or High and see the new size before you save.
Everything you open a PDF for.
And nothing you don’t. No toolbars full of buttons that open a paywall. If you can see it, you can use it.

Click a field and type. Tab to the next one. Checkboxes check.
Redaction that actually redacts.
A black box on top hides nothing. PDF Unlimited removes the text underneath, so there’s nothing left to copy. Learn more

Press Command-F, type a word, and every hit lights up across the whole document, with a list of results in the sidebar.
Feels like it came with your Mac.
Native on Apple silicon and Intel. Dark Mode, tabs, Versions, keyboard shortcuts for everything, and the Liquid Glass look of macOS Tahoe. No Electron, no web view pretending to be an app.

Questions, answered.
Is PDF Unlimited really free?
Yes. Every feature is free, with no trial, no watermark, no ads and no paid tier. You don’t need an account, and you never will.
So what’s the catch?
There isn’t one. PDF Unlimited runs entirely on your Mac, so there are no servers or cloud storage costing money every month. Without those costs, there’s no reason to charge you a subscription.
Can I edit the existing text in a PDF?
Not yet. You can add text anywhere with a text box, annotate, sign, fill forms, redact, and rearrange, merge or split pages. Retyping the original words in place is on the list.
Are my files uploaded anywhere?
No. PDF Unlimited never uploads your files, and the app doesn’t collect analytics. OCR, compression and redaction all happen on your Mac.
Which Macs does it run on?
Any Mac running macOS 14 Sonoma or later, on Apple silicon or Intel. It’s a native app, so it’s fast and light on battery.
How do I make it my default PDF app?
In Finder, select any PDF and press Command-I. Under “Open with,” choose PDF Unlimited, then click Change All.
Make room. Uninstall Acrobat.
PDF Unlimited is free, installs in seconds and never asks for your email. Not even once.
