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