PDF Max Pro - Edit, Sign PDFs

PDF Max Pro is a complete PDF editor for iPhone, iPad, and Mac, trusted by millions of people since 2012.

From signing a form to building research you can verify, PDF Max Pro helps you edit, annotate, organize, understand, study, protect, and deliver PDFs—all in one app.

YOUR PDF. NOW A WORKSPACE.

Collect important passages, highlights, images, tables, formulas, and notes as Cards beside your PDFs. Every Card remembers where it came from, so you can return to the original page whenever you need the full context.

• Search, tag, connect, and arrange your Cards
• Gather related Cards into named groups called Frames
• Organize evidence from several PDFs without merging them
• Compare passages side by side or view your evidence as an Outline or table
• Present Frames or export your work to Markdown, PDF, or Word

STUDY WHAT MATTERS

Turn trusted Cards into Questions, practice a focused topic, or use scheduled Study for long-term review. Track your Progress, study text and visual material, and return to the supporting PDF whenever an answer needs more context.

On supported devices, Apple Intelligence can draft Questions for you to review before saving.
