Convert PDF to Word, PowerPoint & HTML Formats

With as little as 2 lines of code, you can implement robust PDF to Word, PowerPoint or HTML conversion features for your .NET applications.

Save PDF in different formats - C#

        // load the file to be converted
        var pfile = new Aspose.Pdf.Document(dir + "template.pdf");

        // save in different formats
        pfile.Save(dir + "output.docx", Aspose.Pdf.SaveFormat.DocX);

        pfile.Save(dir + "output.pptx", Aspose.Pdf.SaveFormat.Pptx);

        pfile.Save(dir + "output.html", Aspose.Pdf.SaveFormat.Html);

Furthermore, you can either transform each page of a PDF file to conventional raster & vector image formats such as BMP, JPEG, PNG, GIF, EPS, SVG or convert the whole PDF to multi-page TIFF. You may also convert to XLS, EPS, SVG, XPS, LaTex, TXT and PDF/A format with ease.

Create & Manipulate PDF Documents On the Fly

Aspose.PDF for .NET offers the capability to generate documents from scratch. You can use its API or transform images, XML, XSL-FO, HTML, SVG, PCL, XPS, EPUB or simple text files to PDF documents. Moreover, you can specify XMP metadata, author details, creator details, and title information during the PDF generation.

This library is also a good choice when you need to edit or manipulate existing PDF documents. It allows you to concatenate or merge two or more PDF files, append new pages to an existing file, extract pages, insert pages at a particular location in an existing file, split documents or create N-up's (number of pages over the single page) and booklets.

Set Security Constraints for PDF Documents

Aspose.PDF for .NET offers the facility to encrypt and decrypt documents with either 40-bit,128-bit or 256-bit encryption and provides the ability to specify user passwords for further security. Content modification in documents such as copying the content, printing the file, completing form fields, degraded printing, annotation modification as well as document assembly can also be restricted.

API allows you to further improve security mechanism by using PKCS#1, PKCS#7 and PKCS#7 detached signature types, and with the use of the digital certificate. You may specify the certificate level and set the graphical appearance of the signature as per application requirements.

Process PDF Form Fields

Aspose.PDF for .NET provides advanced features beyond simple form fields processing. With this single product, you get a bunch of features from the addition of form fields to advanced abilities such as dynamically rename, remove and copy form fields across the documents, set JavaScript for the push button and flatten form fields. This product is also great when it comes to specifying field attributes such as READ_ONLY, REQUIRED, NO_EXPORT, HIDDEN, NO ZOOM. You can also easily specify visual attributes such as field Alignment, BorderStyle, ButtonStyle, FontSize, TextColor, TextEncoding or define custom positioning to place the form fields at an absolute position within the document.

Aspose.PDF for .NET also supports importing & exporting form fields data from XML, FDF or XFDF files. Moreover, you can bind form fields with OLEDB or ODBCDB data sources. API also allows to import an image or barcode, get field data with rich text formatting or add submit button to post data to a specified URL.

Graph & Imaging Capabilities

Aspose.PDF for .NET provides support for many different types of graphs: graphs can be drawn on any page location specified by coordinates and existing graphs can be rotated and scaled to suit your requirements. You may also try converting images residing on disk, memory or web location, to PDF format. Along with conventional image types, CCITT (fax) images, multi-page TIFF images and transparent GIF images are also supported.

Convert PDF to CCITT4 compressed TIFF - C#

// load the PDF in PdfConverter
using (var converter = new Aspose.Pdf.Facades.PdfConverter())
    converter.BindPdf(dir + "template.pdf");

    // initiate conversion

    // create TiffSettings & set compression type
    var settings = new Aspose.Pdf.Devices.TiffSettings()
        Compression = Aspose.Pdf.Devices.CompressionType.CCITT4,
    // save PDF as TIFF
    converter.SaveAsTIFF(dir + "output.tiff", settings);

Aspose.PDF for .NET also allows you to add, replace, extract or delete images already present in a PDF file. You may also add images as a watermark while generating documents or manipulating existing files.
