Stop Wrestling with PDFs: How fast-convert Makes It Effortless

We've all been there. You need to convert a PDF to Word, extract a few pages, or merge two documents — and suddenly you're deep in a maze of clunky desktop apps, sketchy online tools, or complex Python scripts.
fast-convert changes that.
What is fast-convert?
fast-convert is a lightweight, developer-friendly CLI and library built specifically to handle PDF conversions at speed. Whether you're building an automation pipeline or just need a quick one-liner in the terminal, it delivers.
Key PDF Features
Here's what makes it stand out for PDF workflows:

  1. PDF → Word / DOCX fast-convert input.pdf --to docx --output result.docx Preserves formatting, tables, and images with surprisingly high fidelity.
  2. PDF → Images (PNG/JPG per page) fast-convert report.pdf --to png --dpi 150 Perfect for generating thumbnails, previews, or processing pages individually in an ML pipeline.
  3. Merge multiple PDFs fast-convert merge a.pdf b.pdf c.pdf --output combined.pdf
  4. Split a PDF by page range fast-convert invoice.pdf --split 1-3 --output pages.pdf
  5. Compress PDF size fast-convert heavy.pdf --compress --level medium Using it programmatically (Node.js) import { convert } from 'fast-convert';

await convert('report.pdf', {
to: 'docx',
output: './output/report.docx',
preserveLayout: true,
});
