This latest version has slow and jerky scrolling. It takes a couple of blinks to finally load the page image. ### 1/5 — Step Backwards *2026-08-04, version 27.0.1* 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. ### 1/5 — The new redesign SUCKS *2026-08-03, version 27.0.1* 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 ### 1/5 — Do not pay for this app *2025-12-05, version 4.1.0* 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. ### 1/5 — A APPLE PRECISA VOLTAR A FILTRAR APLICATIVOS QUE FICAM À VENDA!!! ESSE APP É JOGAR DINHEIRO NO LIXO. *2025-11-30* DINHEIRO NO LIXO. APLICATIVO NÃO PRESTA. ### 1/5 — 一点搜索就闪退 *2025-03-18, version 8.1.0* 一点搜索就闪退，希望解决一下 ### 1/5 — Scam *2024-12-08, version 8.1.0* There are two versions of this in the apple App Store. One is free one is 7.99 (Australian dollars). The free has locked features so I bought the paid app, but still the features are locked and it says I have to go ‘premium’ for 80 dollars annually. What the hell is difference between the paid and free app then? Scammed. ### 1/5 — Ads on a paid app? *2024-11-14, version 8.1.0* Once every few days, while I’m using the paid version of the app, I get promoted to download an app for an artificial intelligence application that will summarize notes for you, and the only way to get rid of this notification is to click on the link, be taken to the app store, then go back in this app… absolutely unacceptable. ### 1/5 — Shame on you greedy developer *2024-11-05, version 8.1.0* Tons of in app purchases inside why you named it PDF MAX PRO YOU ARE LOOTING OUR HARD EARNED MONEY UTTER SHAMEFUL ### 2/5 — Not so good any more *2024-05-14* I paid about 10 bucks for the pro version a couple of years ago. I liked its ability to extract pages from a larger document into a single document consisting of the extracted pages. I recently upgraded to an iPad Pro. When I extracted 3 pages, they were not combined into one document, but remained 3 separate pages. It seems that now, more pro features, like merge PDF’s, are available for a $.99 PER WEEK subscription. I ain’t paying $52/year for something I already paid for. Now it crashes when opening documents ## Frequently asked questions about PDF Max Pro ### What can I do with PDF Max Pro?
