unpdf is a TypeScript library providing PDF extraction and rendering utilities that work across all JavaScript runtimes, including Node.js, Deno, Bun, browsers, and serverless edge environments. It bundles a serverless-optimized build of Mozilla's PDF.js and offers simple APIs for extracting text, links, and images from PDF documents.

Use cases

• extract text from pdf files in javascript
• parse pdfs for ai summarization or rag pipelines
• read pdf content in cloudflare workers or edge functions
• extract images and links from pdf documents
• modern replacement for pdf-parse in node
• use pdf.js in deno or bun without node-specific dependencies

When to choose

• you need PDF text extraction that runs in serverless or edge environments
• you want a maintained, multi-runtime alternative to pdf-parse
• you're building AI workflows that ingest PDF documents
• you want a simple API over PDF.js with the option to drop down to the raw PDF.js API

When to avoid

• you need full PDF creation or heavy layout manipulation rather than extraction
• you only target Node.js and already depend on native PDF tooling like pdftotext
• you need OCR of scanned PDFs without a text layer
