The Syncfusion .NET Word Library offers powerful APIs for programmatically converting Word documents to PDF with minimal code in C#, without Microsoft Word or interop dependencies. Additionally, it facilitates converting Word documents to PDF/A format for archival purposes and tagged PDFs compliant with Section 508 (PDF/UA).

Key features of Word-to-PDF conversion
Accessible or Tagged PDF (PDF/UA)
Design an accessible Word document (508-compliant) using Microsoft Word or the Syncfusion .NET Word Library and convert it to an accessible or tagged PDF (PDF/UA) document.
PDF Conformance (PDF/A)
Configure the conformance level of your converted PDF for long-term archiving and standardization.
Fillable PDF Forms
Design your application forms as Word documents using Microsoft Word and convert them to fillable PDF forms using the Syncfusion .NET Word Library.
Alternate Chunks
Import or ignore the embedded alternate chunks (other Word documents) in a document when converting it to PDF.
Bookmarks
Export the paragraphs with heading styles or bookmarks as PDF bookmarks.
Identical Image Optimization
Enable the settings to reduce main memory usage during Word-to-PDF conversion by reusing identical images in the Word document.
Hyphenation
Enables the addition of hyphens to text within a Word document during Word-to-PDF conversion, using specified language dictionaries.
Track Changes
Preserve revision marks in the converted PDF, retaining tracked changes from the Word document and offering customization options for track changes markup.
Comments
Preserve comment balloons in the converted PDF from the Word document. Also, customize balloon colors for enhanced visual clarity.
Font options in Word-to-PDF conversion
Embed Font Subset
Embeds only the font glyphs from TrueType fonts that are used in the document.
Embed Complete Fonts
Embeds the complete set of TrueType fonts used in the document and allows displaying of the document contents uniformly and independent of whether the font is available or not.
Font Substitution
The built-in font substitution event allows users to choose alternate fonts from the device or upload fonts with a few lines of code.
Fallback fonts
Allows the configuration of fallback fonts for Unicode text. These fallback fonts come into play when the rendering engine encounters Unicode text that lacks a corresponding glyph in the specified fonts.
