用可靠的 Word 到 PDF 轉換創建專業的可列印 PDF，該轉換可保持格式並能跨設備顯示一致。

Converting Word to PDF involves transforming DOC or DOCX documents into a fixed, universally supported format that preserves formatting, layout, fonts, and images. This process ensures documents display consistently across different devices, operating systems, and applications, regardless of whether the recipient has Microsoft Word installed. By reducing the risk of unintended edits and layout changes, PDF output provides a more secure and professional way to share finalized content. Typical use cases include distributing reports, proposals, and contracts, preparing documents for printing, sharing files with external stakeholders, and archiving important records for long-term storage or compliance purposes.

Several .NET components offer Word to PDF conversion including:

DevExpress PDF Document API for .NET (part of DevExpress Office File API) lets you convert Word documents to PDFs while preserving layout, fonts, consistency accurately.
ImageGear for .NET lets you convert Word files into PDFs optimized for viewing, printing, archiving, and long-term document preservation needs.
GroupDocs.Conversion for .NET facilitates Word to PDF conversion, maintaining document structure, visual accuracy, and cross-device compatibility.
IronPDF for .NET allows you to transform DOC and DOCX files into reliable PDFs with consistent formatting across platforms.

透過檢視器擷取 PDF 內容

使應用能夠直接從 PDF 文件中提取使用者選擇的文本和區域，從而將檢索到的資料與螢幕上可見的交互對齊。

Extracting content using a PDF Viewer refers to enabling end users or applications to select and retrieve content directly through the viewer’s user interface, based on interactive actions such as text selection, area selection, or page-level capture. For software developers, this means the viewer acts not only as a rendering surface but also as a controlled extraction layer that exposes selected text, images, or regions. This approach is valuable in review, approval, and data capture scenarios because it reflects explicit user intent, aligns extracted data with what is visibly selected on screen, and avoids reliance on background parsing alone, resulting in more predictable and user-driven content retrieval within applications.

Several WinForms PDF Viewer components allow content extraction, including:

DevExpress WinForms PDF Viewer (part of DevExpress WinForms) allows you to extract user-selected text and visual regions directly through the PDF viewer.
Telerik UI for WinForms PDF Viewer (part of Telerik UI for WinForms) allows you to capture visually selected PDF content in the viewer, returning text aligned with user interactions.
PDFView4NET Windows Forms Edition by PDF4DEV Solutions facilitates extracting text, images, and regions directly from its PDF viewer based on user selections.
Syncfusion WinForms PDF Viewer (part of Syncfusion Essential Studio Enterprise) lets you retrieve user-selected PDF text and areas via the viewer.

更改頁面順序以改進文件結構，支援合規需求，更高效地管理複雜的 PDF。

Moving pages in a PDF file refers to the ability to change the order of individual pages within the document. This is typically done by dragging and dropping pages into a new sequence or by specifying where a page should be relocated. The main benefit of this feature is improved document organization, especially in cases where content needs to be restructured for clarity, relevance, or compliance with formatting requirements. It also simplifies tasks such as compiling reports, merging multiple sources, or preparing documents for printing and distribution, making it easier to manage large or complex PDF files efficiently.

Several WPF PDF components allow you to move pages in a PDF, including:

Telerik UI for WPF PdfProcessing (part of Telerik UI for WPF) lets you reorder PDF pages programmatically, enabling the dynamic restructuring of documents in WPF apps.
IronPDF for .NET by Iron Software allows you to reposition pages inside PDFs via code, helping developers customize document flow and prepare files for output or review.
XFINIUM.PDF WPF/UWP EDITION enables page movement within PDFs, giving UWP and WPF applications precise control over document layout and sequence adjustments.
Syncfusion WPF PDF (part of Syncfusion Essential Studio Enterprise) lets you reorder pages in PDF files through its API, supporting document editing and structured presentation.

帶有內置注釋工具的 PDF 檢視器讓使用者在不修改原始內容的情況下審查、評論和協作文件。

PDF annotation in .NET WinForms PDF viewer components refers to the ability to add visual and textual markup directly onto PDF documents without altering the original content. These tools allow users to draw shapes, highlight text, insert comments, and place notes within the viewing interface, supporting workflows such as document review, feedback, and approval. This functionality improves collaboration and clarity in document handling, making it well-suited for document processing tasks in WinForms applications.

Common features include:

Freehand Draw (Ink Annotation) allows users to sketch, underline, or handwrite directly on the page using a mouse, stylus, or touch input, making it ideal for markups and signatures.
Lines provide a simple way to connect points or emphasize linear elements within a document, often with configurable thickness, color, and opacity.
Rectangles enable users to highlight or frame areas of interest, supporting both outlined and filled styles for visual emphasis.
Ellipses offer a similar highlighting function to rectangles but with a rounded shape, useful for circling content or marking irregular regions.
Arrows are commonly used to direct attention to specific content, combining line styling with arrowheads to clearly indicate focus or flow.
Sticky Note annotations allow users to attach comments to precise locations in the document, typically displayed as icons that reveal text on interaction.
Free Text enables direct placement of typed text onto the page with control over font, size, color, and alignment, supporting clear, visible commentary without pop-ups.
