Syncfusion Feedback


A PDF (Portable Document Format) is a fixed document used to display the document contents uniformly and independent of application software, hardware, and operating system. The Syncfusion .NET Word library (Essential DocIO) converts a Word document to PDF with as little as 5 lines of code. You can prepare your document for long term archiving by converting to PDF with conformance level ‘PDF/A1B’ or ‘PDF/X-1a:2001’.

Key Features

Fast and Reliable

Converts complex Word documents to PDF faster in a batch process, compared to Office automation libraries.

Partial Trust Environment

Converts Word documents to PDF in partial trust environments like Azure.

Platform Independent

A non-UI component allows you to automate conversion of Word documents to PDF in .NET Framework, .NET Core, and Xamarin platforms.

Font options

Embed Font Subset

Embeds the font glyphs from the TrueType fonts only for the characters used in the document (best for reducing file size).

Embed Complete Font

Embeds the complete TrueType fonts used in the document and allows displaying the document contents uniformly and independent of whether the font is available or not.

Font Substitution

Our built-in font substitution event allows you to choose alternate fonts from the device or upload the required fonts in a few lines of code.

Word to PDF options

Accessible or Tagged PDF

Design your accessible Word document (508 compliance) using Microsoft Word or the Syncfusion Word library (Essential DocIO) and convert it to Accessible or Tagged PDF documents.

Form Fields

Design your application forms as Word documents using Microsoft Word and convert them to fillable PDF forms using the Syncfusion Word library (Essential DocIO).

Alternate Chunks

Allows the user to import or ignore the embedded alternate chunks (another Word document) into the document when converting to PDF.


Exports the paragraphs with heading styles or bookmarks as PDF bookmarks.

PDF Conformance

Allows the user to configure the conformance level of their converted PDF as ‘PDF/A1B’ or ‘PDF/X-1a:2001’.

Optimize PDF Size

Optimize Image

Maintains identical images as single copy within the converted PDF to reduce file size when the same image is used multiple times in the Word document.

Image Quality

Allows the user to adjust JPEG image quality and resolution for optimizing the converted PDF file size.
