About PDF to HTML

The PDF to HTML converter is an advanced online tool that transforms PDF document text content into HTML format while preserving layout information. Unlike simple text extraction, this tool extracts text elements from each PDF page along with their positioning coordinates and font sizes, reconstructing them as an HTML document that closely matches the original layout.

The tool features automatic heading level detection (h1–h6) based on font sizes, ensuring the generated HTML has proper semantic structure for accessibility and SEO. Converted HTML files can be opened directly in any browser with full support for text selection, copying, and editing. Metadata including the source filename, conversion timestamp, and total page count are automatically embedded.

Ideal for converting text-centric PDF documents—reports, research papers, manuals, whitepapers—into web-viewable, editable, and reusable formats. All processing occurs entirely within your browser, making it safe for sensitive and confidential documents. The tool handles corrupted PDFs gracefully and provides clear error messages for better user experience.
