What's New in PDF Max Pro

27.5.0

September 15, 2026

Made for iOS 27, and Siri finds your PDFs. A NEW LOOK • Tools on floating glass. The ribbon breaks into islands — back and sidebar, the tabs, undo and redo — with the tool panel on its own rounded island below. • Pages reach the edges. The document fills the screen and scrolls behind the ribbon, so there is more page and less chrome. SEARCH WITH SIRI • Open a PDF by name. "Open Rental Agreement in PDF Max." Face ID, Touch ID or your passcode confirms before the file opens. • Search out loud. "Search PDFs in PDF Max" lands in My Files with the search panel already filled in. • A Siri & Search panel on the My Files toolbar controls what Siri can do. Letting Siri see the contents of your PDFs is opt-in and stays off until you turn it on. Requires iOS 27 or iPadOS 27. Siri availability varies by language and region. ALSO IN THIS UPDATE • Ask My Library. Ask a question across your saved PDFs and research. Answers are generated on your device. Needs iOS 27 or iPadOS 27 with Apple Intelligence. • Continue reading. On iPhone, Home keeps the last PDF you opened and the page you left on. • Presentation controls now fit every iPhone in portrait, so End is always reachable.

How to cancel PDF Max Pro subscription ⁉️

User reviews

Otra vez me la cobran?

Durante mucho tiempo fue adquirida y hoy me manda que vuelva a comprar, que es lo que pasa con estas app.

Latest update ruined it for me.

The precious version was fast and smooth. This latest version has slow and jerky scrolling. It takes a couple of blinks to finally load the page image.

Step Backwards

Doesn’t seem to be able to work with mail attachments to directly send to iPhone PDF Max app after the recent upgrade. We rely on these apps for efficient workflow only to be forced to update and the app doesn’t work properly when on time crunch.

The new redesign SUCKS

The app update completely erases my bookmarked pages from all the books I had in my library. The new voices are horrible and don't read the pages right. This is NOT what I initially paid for?! I want the old version back please

Do not pay for this app

I paid $48.99 for 1 year’s subscription so I can edit PDFs daily only for the app to immediately crash upon opening any file and no contact information to reach the seller. This app is a scam and should be removed from the store.
