Convert HTML pages to PDF on the fly.
ExpertPDF HtmlToPdf Converter is a .NET component that converts HTML content into PDF documents from applications or services. It processes web pages, HTML strings, and local files while preserving layout, images, and styles. Developers can integrate PDF generation into web or desktop solutions with configurable rendering and page settings.

URL and HTML String Conversion

Convert entire web pages from URLs or raw HTML strings into PDF documents, with support for base URLs to correctly resolve relative resources.

Output Flexibility

Save converted PDFs to files, streams, byte arrays, or manipulate them further as in-memory PDF document objects.

Page Layout Customization

Set PDF page sizes, orientations, margins, and scaling options to tailor document appearance precisely.

Headers and Footers

Add customizable headers and footers with HTML content, images, page numbering, and custom elements on every page.

Security and Digital Signatures

Apply encryption, user and owner passwords, permission controls, and include digital signatures to secure documents.

Advanced Content Control

Preserve or disable hyperlinks, insert automatic or CSS-driven page breaks, exclude specific HTML regions, and convert only selected page sections.

Bookmarks and Internal Links

Automatically generate PDF bookmarks from specified HTML tags and convert HTML anchors into interactive internal PDF links.

Multithreading and Performance

Designed to function reliably in multithreaded applications like ASP.NET, ensuring no resource leaks during high-volume conversions.

Rendering Engine and Standards Support

Uses an internal WebKit-based rendering engine supporting HTML5, CSS3, modern JavaScript, and web fonts with no external dependencies. Supports PDF standards like PDF/A and PDF/X.

Merge and Post-Conversion Editing

Append multiple HTML sources or existing PDFs into a single document and modify PDFs after conversion by adding pages, texts, images, shapes, and annotations.
