## What it is
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

## Facets
- artifact type: library
- maturity: active
- function: pdf, parser, ocr
- domain: pdf, files, developer-tools
- platform: bun, browser, cross-platform, serverless, cloud
- tags: pdfjs, text-extraction, serverless, edge, cloudflare-workers, ai-pipelines, natural-language-processing, nodejs, deno
