Develop software using advanced document optimising API, create high-level, platform-independent code for .NET and .NET Core platforms. This is a powerful solution to compress documents and images in C#, F#, VB.NET.
Make large files smaller without loss of quality. Delete unnecessary and unused data. Shrink the size of Word and HTML files in C#. Our C# library provides developers with an integrated API to optimize documents in various formats.
This C# library is a stand-alone solution and doesn't require any third party software installed.
The maximum effect can be obtained by optimizing high-resolution images, as well as documents containing such images. Our C# library will help you to compress DOCX, DOC, RTF, ODT, EPUB, HTML, JPG, PNG files.
Optimization of documents without loss of quality made easy with 'Aspose.Words for .NET'. The following example shows how to shrink the size of a Word document in C#:
using Aspose.Words;
var doc = new Document("Input.docx");
doc.Cleanup();
var nodes = doc.GetChildNodes(NodeType.Shape, true);
foreach (Shape shape in nodes)
{
if (shape.IsImage)
{
// It's up to developer to choose the library for image compression.
using var image = Image.FromStream(shape.ImageData.ToStream());
// ...
// Compress image and set it back to the shape.
shape.ImageData.SetImage("yourCompressedImage");
}
}
var saveOptions = new OoxmlSaveOptions
{
CompressionLevel = CompressionLevel.Maximum
};
doc.Save("Output.docx", saveOptions);using Aspose.Words;
var doc = new Document("Input.docx");
doc.Cleanup();
var nodes = doc.GetChildNodes(NodeType.Shape, true);
foreach (Shape shape in nodes)
{
if (shape.IsImage)
{
// It's up to developer to choose the library for image compression.
using var image = Image.FromStream(shape.ImageData.ToStream());
// ...
// Compress image and set it back to the shape.
shape.ImageData.SetImage("yourCompressedImage");
}
}
var saveOptions = new PdfSaveOptions
{
CacheBackgroundGraphics = true
};
doc.Save("Output.docx", saveOptions);
using Aspose.Words;
var doc = new Document("Input.docx");
doc.Cleanup();
var nodes = doc.GetChildNodes(NodeType.Shape, true);
foreach (Shape shape in nodes)
{
if (shape.IsImage)
{
// It's up to developer to choose the library for image compression.
using var image = Image.Fromstream(shape.ImageData.ToStream());
// ...
// Compress image and set it back to the shape.
shape.ImageData.SetImage("yourCompressedImage");
}
}
doc.Save("Output.docx");
using Aspose.Words;
var doc = new Document("Input.docx");
doc.Cleanup();
var nodes = doc.GetChildNodes(NodeType.Shape, true);
foreach (Shape shape in nodes)
{
if (shape.IsImage)
{
// It's up to developer to choose the library for image compression.
using var image = Image.FromStream(shape.ImageData.ToStream());
// ...
// Compress image and set it back to the shape.
shape.ImageData.SetImage("yourCompressedImage");
}
}
var saveOptions = new OoxmlSaveOptions

};
doc.Save("Output.docx", saveOptions);
using Aspose.Words;

JpegQuality = 50
};
const double maxPageDimension = 1584;
var pagesStream = renderer.SavePdfAsImages(pdfStream, pdfReadOptions);
var builder = new DocumentBuilder();
for (var i = 0; i < pagesStream.Count; ++i)
{
// Set maximum page size to avoid the current page image scaling.
var pageSetup = builder.PageSetup;
SetPageSize(pageSetup, maxPageDimension, maxPageDimension);
var pageImage = builder.InsertImage(pagesStream[i]);

};

private void SetPageSize(PageSetup pageSetup, double width, double height)
