How it works

  1. 1

    Upload your large PDF

    Pro users can send files well beyond typical free-tool caps via our resumable chunked upload API.

  2. 2

    VPS worker converts offline

    The job runs on Hetzner infrastructure with LibreOffice — not a fragile browser-only script.

  3. 3

    Download when ready

    Poll job status and download your DOCX from a secure signed URL when conversion completes.

Use cases

University textbooks

Convert 500-page PDF course packs into Word for annotation.

Annual SEC filings

Finance teams extract sections from hundred-megabyte reports.

Technical manuals

Engineering PDFs with hundreds of diagrams still need editable text layers.

Problems we solve

Browser tab crashes

Client-only converters load entire files into RAM. Our VPS streams and processes on the server.

Arbitrary upload ceilings

We support much larger inputs for paid plans than 5–12 MB free competitors.

Timeouts on slow connections

Chunked uploads resume if your network drops mid-transfer.

Trust & privacy

Hetzner EU data centers

Heavy jobs run on dedicated VPS hardware in Europe.

Queue visibility

Track upload, assembly, and conversion progress in the UI.

Edge handoff

Small files still use fast Next.js Edge routes; only large files hit the VPS.
