document.Save();

Shared HTML behavior for every converter

OfficeIMO.Html owns HTML/MHTML parsing, resource policy, base-URI resolution, accessible structure, layout scenes, and direct image rendering. Word, Excel, PowerPoint, Markdown, RTF, Email, and PDF adapters reuse this owner instead of implementing separate web-content rules.

using OfficeIMO.Html;

HtmlConversionDocument source = HtmlConversionDocument.Parse(
    "<h1>Status</h1><p>Generated by OfficeIMO.</p>");
byte[] png = source.ToPng(new HtmlRenderOptions { ViewportWidth = 720 });

Outputs and projections

  • Render directly to PNG, JPEG, TIFF, SVG, and lossless WebP.
  • Create PDF output with OfficeIMO.Html.Pdf.
  • Convert semantic content to Word, Markdown, and RTF through their focused adapter packages.
  • Load and save MHTML archives with bounded resource handling and deterministic root-part selection.
  • Apply URL, media, size, node, and depth policies before untrusted web content enters a document workflow.
