@firecrawl/pdf-inspector-wasm
Browser WebAssembly bindings for pdf-inspector. Classify PDFs and extract structured Markdown locally from a Uint8Array, using the same Rust core as the native Node.js, Python, and Rust packages.
Install
npm install @firecrawl/pdf-inspector-wasm
Usage
import init, { processPdf } from "@firecrawl/pdf-inspector-wasm";
await init();
const response = await fetch("/annual-report.pdf");
const pdf = new Uint8Array(await response.arrayBuffer());
const result = processPdf(pdf);
console.log(result.pdfType);
console.log(result.markdown);
Pass options when you need selected pages or compact Markdown:
const result = processPdf(pdf, {
pages: [1, 3, 5],
profile: "compact",
includePageMarkers: true,
});
The package also exports:
detectPdf(pdf, options?)for detection without extraction.classifyPdf(pdf)for the lightweight result shape shared with the native Node.js API.extractText(pdf)for plain text.version()for the WASM package version.
Browser behavior
- Parsing runs locally. PDF bytes are not uploaded anywhere.
- The build is single-threaded and does not require cross-origin isolation.
- CMaps are embedded so CJK font decoding does not depend on a filesystem.
- Extraction is synchronous after
init(). For large documents, call it from a Web Worker to keep the UI responsive. - Image-only documents still require a separate OCR step.
