What is ComposePdf?

ComposePdf is a Kotlin Multiplatform library for rendering PDFs and extracting text, built atop pdfium with a Compose Multiplatform-first API. Drop ready-made PDF page viewers or thumbnails into your KMP app's UI on desktop, Android, iOS, or web, complete with progressive loading, zoom controls, and selectable/copyable text. It's a github kotlin library that ships to Maven Central, perfect for kotlin multiplatform compose apps needing PDF support without native hacks.

Why is it gaining traction?

In a sea of JavaScript PDF libs, this stands out for KMP devs with seamless Compose integration—no wrestling separate view hierarchies or webviews. Features like pixel-perfect text selection (using per-char boxes), two-tier caching for smooth scrolling, and zero-copy rendering deliver snappy performance across targets, from kotlin multiplatform desktop to kotlin multiplatform ios and web. It's a clean github kotlin multiplatform example that beats kotlin multiplatform vs flutter headaches for native-feeling PDF UIs.

Who should use this?

KMP teams building document apps, ebook readers, or file managers with PDF previews, thumbnails, search highlights, or text extraction. Suited for Compose Multiplatform mobile/desktop devs ditching heavy webviews, or those prototyping kotlin multiplatform web viewers via Kotlin/JS or Wasm. Ideal if you're leveraging kotlin github actions for CI or kotlin github release workflows.

Verdict

Grab it for KMP PDF prototypes—docs and samples make starting fast, with real polish like password support and metadata reads. At 20 stars and 1.0% credibility score, it's early; test thoroughly before production, but a promising kotlin github repo for multiplatform wizards.
