Convert Word DOCX and Text to PDF

Convert DOCX and TXT to PDF — entirely in your browser

This tool uses two open-source JavaScript libraries that run locally:
    1. mammoth.js — parses the Open XML format inside a .docx file (which is actually a ZIP archive containing XML documents). It extracts the text content, headings, bold/italic marks, and list structures.
    2. jsPDF — takes the extracted content and renders it to a standard A4 PDF, handling text layout, line wrapping, and page breaks.
Your document is never transmitted to a server. The entire pipeline runs inside your browser tab.

What is and isn't preserved

Because the conversion runs in a browser without Microsoft Word's rendering engine, not all Word formatting translates perfectly:
ElementStatus
Text content✅ Fully preserved
Bold, italic, underline✅ Preserved
Headings (H1–H6)✅ Preserved with size hierarchy
Bullet and numbered lists✅ Preserved
Tables (basic)⚠️ Simplified (no merged cells)
Embedded images⚠️ Omitted in current version
Complex page layouts⚠️ Normalised to single-column
Track changes / comments❌ Not supported
Custom fonts❌ Replaced with PDF standard fonts

For simple documents — resumes, essays, reports, letters — the output is clean and professional. For complex multi-column Word templates, a desktop tool with the full Word rendering engine will give better fidelity.

How to convert your document

  1. Upload — Drop a .docx or .txt file. mammoth.js reads the DOCX ZIP container and extracts document.xml.
  2. Conversion runs automatically — jsPDF renders the content to A4 layout.
  3. Download — Click Download to save your PDF, compatible with all standard PDF viewers.

FAQs about Document to PDF

Everything you might be wondering — answered.

Which libraries power the DOCX parsing and PDF creation?+
mammoth.js for DOCX parsing (it reads the Open XML format used by Word 2007+) and jsPDF for PDF generation. Both run entirely in the browser via JavaScript.
Will complex Word formatting be preserved?+
Basic formatting (bold, italic, headings, paragraphs, bullet lists) is preserved. Complex elements like precise page breaks, floating images, tables with merged cells, embedded charts, and track changes are either normalised or omitted, because these require Microsoft's proprietary rendering engine to replicate perfectly.
Is my document uploaded to a server?+
No. Both mammoth.js and jsPDF run as JavaScript in your browser tab. Your document file stays on your device throughout the entire conversion.
Can I convert plain .txt files?+
Yes. Plain text files are read directly and rendered to PDF with standard body text formatting — no mammoth.js parsing needed for .txt.
