Built for Mobile

What Is the Foxit Mobile PDF SDK?

Native iOS and Android PDF libraries your team can ship in days, not months.

Foxit Mobile PDF SDK embeds PDF viewing, annotation, forms, signing, search, and security directly into iOS and Android applications. It runs natively on-device with no server calls at runtime, and ships with a built-in UI Extension component — a working PDF viewer you can brand and customize.

What Your Team Gets from Building on It

Ship faster, render consistently on the devices your users carry, and pass app review without PDF-library questions.

UI Extension

Native UI, Out of the Box

A working PDF viewer from day one, customizable to your design system and brandable to your product. Your mobile team does not need PDF expertise to ship a reader, an annotation flow, or a signing screen, so the feature lands in a release cycle rather than a roadmap quarter.

On-device

Works Offline, Renders Natively

Rendering happens on the device with no server calls at runtime, so field teams, clinicians, and inspectors open documents with no signal. Native performance keeps large files smooth on the mid-range phones most of your users actually carry, and documents never leave the handset.

One codebase

Ship iOS and Android Together

The same feature set and the same rendering output across both platforms, with React Native, Cordova, and Xamarin bindings for teams running a single codebase. You review one integration, not two, and your QA matrix stops doubling.

Policy Compliant

Cleared for App Review

Compliant with Apple App Store and Google Play third-party SDK policies, with a library footprint sized for mobile distribution. PDF licensing questions do not stall your release, and app-store size limits stay a non-issue.

Core Capabilities

What Can the Mobile SDK Do?

Everything your app needs to work with PDFs, running on-device.

View & Render

Viewing & Rendering

Accurate rendering of complex documents across the full range of iOS and Android hardware, from phones to wearables.

Explore

Annotations

Annotations & Markup

Create, edit, import, and export the full range of PDF markup types, with native touch and stylus input.

Common Questions

Frequently Asked Questions About the Foxit Mobile SDK

What engineering leads ask most when evaluating a native PDF library.

The Foxit Mobile PDF SDK is a native library that embeds PDF viewing, annotation, forms, digital signing, full-text search, and security into iOS and Android applications. It includes a built-in UI Extension component — a ready-to-use PDF viewer you can customize and brand — and is built on Foxit's proprietary rendering engine.
Yes. Both the iOS and Android SDKs ship with a UI Extension component: a fully functional PDF viewer you can drop into your application and then customize to match your design system. Teams without deep PDF expertise typically have a working viewer running the same day.
iOS supports Swift, Objective-C, and C++. Android supports Java, Kotlin, and C++. Cross-platform binding libraries are available for React Native and Cordova on both platforms, and Xamarin on iOS.
iOS 9.0 or higher with Xcode 9.0 or newer, and Android 4.x or higher on 32/64-bit ARM or 32-bit x86 devices. iOS builds target iPhone, iPad, Apple Watch, and CarPlay. Android builds target phones, tablets, Chromebooks, and Android Auto.
Yes. The SDK processes documents locally inside your application — no runtime server calls and no third-party upload dependency, so user documents stay on-device. It also supports native PDF encryption and decryption, Microsoft RMS, and custom DRM.
Yes. Because rendering and processing happen entirely on-device, the SDK functions with no network connection. This suits field service, aviation, healthcare, and other environments where connectivity is unreliable or restricted.
The Mobile SDK is a native iOS and Android library compiled into your application. The Web SDK is a client-side JavaScript library that runs in a browser. Both are built on the same Foxit rendering engine and share a common feature set. Teams shipping a native app choose Mobile; teams embedding PDFs in a web application choose Web.
The 30-day trial includes full SDK access for your chosen platform, documentation, and sample projects. Commercial licensing is by quote — Foxit sales engineers help scope platform, add-on modules, and distribution model during the trial.
