## How Browser-Native PDF-to-DOCX Reconstruction Works Without Cloud Servers

![Client-side PDF to Word OpenXML in-memory conversion architecture diagram](https://zeeml.com/assets/diagrams/pdf-to-word.webp)

Traditional online PDF converters upload your files to remote cloud queues, creating data-privacy risks for legal, medical, and academic documents.

ZeeML loads the PDF byte buffer directly into a client-side WebAssembly worker, extracts positioned text runs from each page tree, reconstructs paragraph boundaries by vertical coordinate clustering, and compiles a valid OpenXML (.docx) archive in memory.

## Frequently Asked Questions

### Are my PDF files uploaded to ZeeML servers during conversion?
No. The entire PDF parsing and Word (.docx) packaging pipeline runs locally inside your browser using JavaScript and WebAssembly.

### Does the converter preserve page breaks from the original PDF?
Yes. Each page boundary in the source PDF is mapped to an explicit OpenXML page break (<w:br w:type="page"/>) in the generated Word document.

### Can I edit the extracted text before downloading the Word (.DOCX) file?
Yes. Once you select or drop a PDF, the extracted paragraphs appear in the live preview editor where you can make edits before exporting to .DOCX, .TXT, or .MD.

### Can I export a PDF directly to Markdown (.MD) or Plain Text (.TXT)?
Yes. Select the Plain Text (.TXT) or Markdown (.MD) format pill in the workstation header to export clean UTF-8 text or Markdown with automatic heading promotion.
