About PUB to HTML Conversion
PUB to HTML conversion transforms Microsoft Publisher documents into web-ready HTML that displays in any browser on any device. Publisher files are proprietary and require Microsoft Publisher to open — HTML makes the same content universally accessible on the web, on intranets, and in content management systems.
Our converter processes the PUB file through LibreOffice's import engine, translates the layout and formatting into HTML elements and CSS styles, and produces a clean web page with embedded or referenced images. The result can be hosted on any web server or used as a starting point for web design.
Why Convert PUB to HTML?
Publisher documents — newsletters, flyers, brochures, catalogs — contain content that is valuable beyond print. Converting to HTML puts this content on the web where it can reach audiences via search engines, social media, and direct links. HTML content is also accessible to screen readers and assistive technologies that cannot read PUB files.
For organizations publishing recurring content in Publisher, HTML conversion enables dual-channel distribution: print via Publisher's native output and web via HTML conversion. The same content reaches both audiences without manual recreation.
Common Use Cases
- Publishing newsletter content on organization websites and intranets from Publisher source files
- Creating web-accessible versions of Publisher brochures and marketing materials
- Making Publisher-designed content available to users without Microsoft Publisher installed
- Migrating Publisher content to web-based content management systems like WordPress or Drupal
- Archiving Publisher documents in a universally accessible web format
How It Works
The conversion processes Publisher content through LibreOffice's PUB import filter, translates layout elements to HTML5 semantic markup and CSS3 styling, extracts images as separate files (PNG/JPEG), and produces a valid HTML5 document. Publisher's frame-based layout model is translated to CSS positioning where possible, falling back to linearized content flow for complex layouts.
Quality & Performance
Text, headings, lists, and tables convert with good fidelity. Images are extracted at original resolution. Publisher's complex visual layouts (overlapping text frames, wrapped images, decorative elements) are approximated in CSS but may not match the pixel-perfect print layout. The HTML is functional and readable, prioritizing content accessibility over exact visual reproduction.

- 5Keep the original PUB file for print output — HTML is for web distribution
PUB to HTML makes Publisher content web-accessible, extending the reach of print-designed documents to browsers, search engines, and content management systems.
