What's New in PDF Max

27.6

October 30, 2026

Sharper, faster pages, and every tool in one row. • Beautiful & powerful on iPhone Duo • Sharp at every zoom: text and markup stay crisp while you zoom and scroll, with no blurry pass. • Smoother pages: a new PDF engine scrolls and zooms with far fewer dropped frames, even in long documents. • One-row ribbon: on iPhone and iPad the ribbon fits in a single row, leaving more room for your page. Groups that don't fit move into More instead of being cut off, and Cut and Copy sit beside Paste. • Made for every iPhone, including the iPhone Duo cover screen: the ink, stamp and signature galleries fit the row. • A cleaner look: lighter icons, and menus that open on whichever side has room. • Print-ready PDFs: fonts embedded in the PDFs you save now pass the checks print services run. • No more growing files: saving a PDF you didn't change no longer makes it bigger. • On iPhone, tapping a page in Edit PDF opens that page for editing. • Last Used zoom remembers Fit Width or Fit Page, and documents open faster. • Safer saving: closing a document while a sheet is open saves it first, a PDF you just saved no longer asks again, and moved pages keep their order. • Selection, search and markup follow the text on more PDFs, plus many other fixes.

User reviews

Defeito

Não consigo abrir meus textos depois da última atualização. Muito triste isso. Todos os meus estudos e anotações nos livros e artigos foram perdidos.

Crashing

I have always enjoyed this app. However, I just downloaded the latest version on my new iPhone 13, which has the latest iOS on it. And PDF Max keeps crashing every time I try to annotate a page. I never had that problem with the older version on any device! What can be done to fix this problem?

Stopped working having not long renewed subscription

App now crashes every time I go to create a PDF or try saving a current one. Have tried the fixes google recommends but none work and no support available on website.

bom mas o kybook 3 é melhor

alem de caro o app tem alguns problemas, então acabei optando pelo kybook 3

Great app when works

I purchased the pro app but for some reason does not transfer all documents from the basic version.
