## What it is
A build project that compiles Google's PDFium PDF rendering library for multiple platforms including iOS, Android, macOS, and WebAssembly. It provides prebuilt native libraries so developers can embed PDF rendering in mobile and web applications.

## Use cases
- render pdfs in an ios app
- embed pdfium in an android app
- build a pdf viewer for the browser with wasm
- compile pdfium for apple silicon macos
- get prebuilt pdfium binaries for multiple platforms
- display pdf files locally in a web app without uploading

## When to choose
- you need PDFium-based PDF rendering on iOS, Android, macOS, or WebAssembly and want prebuilt binaries without fighting Google's build system
- you want a client-side PDF viewer that runs entirely in the browser

## When to avoid
- you need Linux or Windows builds, which are still on the roadmap
- you need a full PDF viewer UI rather than a rendering library
- you just need to read PDF metadata in Python, where lighter-weight libraries suffice

## Facets
- artifact type: library
- maturity: active
- function: pdf, sdk, developer-tools
- domain: pdf, files, developer-tools, cross-platform
- platform: wasm, cpp, python
- tags: pdfium, build-scripts, chromium, wasm, mobile, ios, android, macos
