File Format Conversion

Convert documents to high-fidelity renditions with the Document Filters SDK

Applications often need to convert files into a different format. Many software toolkits can handle a few formats well. What if you need to convert just about any format with near-pixel-perfect rendering precision? That’s where you need Document Filters. Supporting hundreds of file formats and deep text and metadata extraction, Document Filters allows the developers to easily embed robust file format conversion functionality into their applications.

Enhance your apps with file format conversion capabilities

Converting files into text, HTML, structured XML, paginated HTML, multipage TIFFs, images (JPG, BMP, PNG), searchable PDFs, and other image and text formats or even your own proprietary formats
Support for over 550 file formats
Replicate original files through the Layout Engine that maps out exact, pixel-by-pixel coordinates of text, images and objects instead of relying on simple character positioning
Render files at the page level and control the size of output and other variables, making it easy to create thumbnails or convert files with or without headers and footers
Apply precise redaction marks, annotations, Bates stamps and watermarks to content during output without the need for a third-party image manipulation package
Extract and convert previously hidden information such as tracked changes, comments, notes, annotations and embedded links
Perform optical character recognition (OCR) of document images to extract and manipulate textual data
Extract and convert contents of packaged, archived, compressed, and other container files
Deploy it your way - Document Filters runs natively on 27 platforms and flexible APIs give you the choice of language to integrate with your application

Using Document Filters is easy! Here is the sample code to convert file format with less than 15 lines of code!

Converting a Word document to PDF

class Program
{
    // Create a multi-page PDF from a source file
    static void Run(string sourceFile, string outputFile)
    {
        // Create an initialize an instance of the Document Filters API
        var docFilters = new DocumentFilters();
        docFilters.Initialize(LICENSE_KEY);

        // Load the source document ready for processing
        var doc = docFilters.GetExtractor(sourceFile);
        doc.Open(isys_docfilters.IGR_BODY_AND_META | isys_docfilters.IGR_FORMAT_IMAGE);

        // Create a PDF canvas
        var canvas = docFilters.MakeOutputCanvas(outputFile, isys_docfilters.IGR_DEVICE_PDF, "");

        // Render each page of the document into the PDF
        for (int pageIndex = 0; pageIndex < item.GetPageCount(); pageIndex++) {
            canvas.RenderPage(doc.GetPage(pageIndex))
        }
    }
}

Converting a Word document to PNG

class Program
{
    // Create one PNG per page
    static void Run(string sourceFile, string outputDirectory)
    {
        // Create an initialize an instance of the Document Filters API
        var docFilters = new DocumentFilters();
        docFilters.Initialize(LICENSE_KEY);

        // Load the source document ready for processing
        var doc = docFilters.GetExtractor(sourceFile);
        doc.Open(isys_docfilters.IGR_BODY_AND_META | isys_docfilters.IGR_FORMAT_IMAGE);

        // Render each page to it's own PNG
        for (int pageIndex = 0; pageIndex < item.GetPageCount(); pageIndex++) {
            using (var canvas = docFilters.MakeOutputCanvas(System.IO.Path.Combine(
            outputDirectory, $"page-{pageIndex+1}.png", 
            isys_docfilters.IGR_DEVICE_IMAGE_PNG, "")) {
                canvas.RenderPage(doc.GetPage(pageIndex))
            }
        }
    }
}
