Single Document Modification Operations

Perform multi-functional document manipulation features in a variety of document formats such as Word, Excel spreadsheet, Presentations, RTF, PDF, Visio, HTML, OneNote, XPS and many others by adding just a few lines of C# code.

The major single document operations include moving pages within a document to a new position, removing a single page or a collection or selected pages, swapping the page positions, extracting specific pages from the document, changing the page orientation to portrait or landscape mode and rotating the pages of the source document to 90, 180 or 270 degree angle.

What is PDF file format?

PDF (Portable Document Format) is a widely used document file format developed by Adobe Systems in 1993. It was specifically designed to provide a platform-independent solution for storing and sharing documents across various operating systems and over the Internet. PDFs utilize a vector-based drawing model, storing graphical elements such as lines, shapes, and images as mathematical equations. This unique approach ensures that PDFs are resolution independent, guaranteeing consistent document quality regardless of the viewing device or program.

One of the key advantages of PDFs is their support for a range of security features. Encryption, password protection, digital signatures, and document watermarking are among the security measures available. These features make PDFs highly secure and suitable for sensitive documents, such as medical records, legal documents, government forms, and invoices. The printing industry also heavily relies on PDFs to facilitate electronic communication with customers.

Creating PDFs is a straightforward process, as they can be generated from various electronic document formats, including Word documents, PowerPoint presentations, and webpages. It’s important to note that PDFs are typically not editable directly. To modify the content of a PDF, it must first be converted to a different file format that supports editing. Numerous software programs, many of which are freely available for download, offer the functionality to convert PDFs to editable formats.

PDFs have gained immense popularity and have become a standard method for document sharing due to their versatility, security features, and consistent formatting. Their compatibility across different devices and operating systems ensures seamless document access for users. Additionally, PDFs preserve the layout, fonts, and images of the original document, making them an ideal choice for sharing visually rich content.
