The Best PDF Editor Apps for iPhone and iPad
1. PDF Expert (Readdle) — Best for Apple devices
PDF Expert is the app many iPhone and iPad owners reach for first. It edits text and images directly, handles annotation beautifully, supports Apple Pencil, and feels fast and native on Apple hardware. With a matching Mac app and iCloud sync, it fits the Apple ecosystem like a glove. Core reading and markup are free, with editing in the Pro upgrade.
2. Adobe Acrobat — Best cross-platform standard
If you move between an iPhone, a Windows PC, and the web, Acrobat keeps everything consistent. It offers trusted editing, form filling, signatures, and cloud storage, plus AI-assisted document tools. It is the dependable choice when other people rely on your output and compatibility matters.
3. PDFgear — Best free editor
PDFgear delivers a remarkable amount for free: editing, conversion, annotation, signing, and an AI assistant, with no paywall on the essentials. If you want capable editing without a subscription, it punches well above its price of zero.
4. Foxit PDF Editor — Best for business workflows
Foxit brings professional-grade editing to iOS, including OCR, an AI assistant, and strong collaboration and security features. It suits people who produce and revise business documents on the go and want more than simple markup.

UPDF combines editing, OCR, annotation, and AI features with cross-platform licensing that covers iOS, Android, Windows, and Mac. For people who want one affordable tool everywhere, it is a compelling package.
7. Xodo — Best free cross-device option
Xodo pairs smooth reading with annotation, form filling, signing, and page management, and it syncs with popular cloud services. It is a great free pick if you share documents across mixed iPhone, iPad, and non-Apple devices.
