Develop software using advanced document optimising API to create portable, robust and secure software in Java. This is a powerful solution to compress Word, Web documents using Java.
Make large files smaller without loss of quality. Delete unnecessary and unused data. Shrink the size of Word and HTML files in Java. Our Java library provides developers with an integrated API to optimize documents in various formats.
This Java 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 Java 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 Java'. The following example shows how to shrink the size of a Word document in Java:
import com.aspose.words.*;
Document doc = new Document("Input.docx");
doc.cleanup();
NodeCollection nodes = doc.getChildNodes(NodeType.SHAPE, true);
for (Shape shape : (Iterable<Shape>) nodes)
{
if (shape.isImage())
{
// It's up to developer to choose the library for image compression.
BufferedImage image = ImageIO.read(shape.getImageData().toStream());
// ...
// Compress image and set it back to the shape.
shape.getImageData().setImage("yourCompressedImage");
}
}
OoxmlSaveOptions saveOptions = new OoxmlSaveOptions();
saveOptions.setCompressionLevel(CompressionLevel.MAXIMUM);
doc.save("Output.docx", saveOptions);
import com.aspose.words.*;
Document doc = new Document("Input.docx");
doc.cleanup();
NodeCollection nodes = doc.getChildNodes(NodeType.SHAPE, true);
for (Shape shape : (Iterable<Shape>) nodes)
{
if (shape.isImage())
{
// It's up to developer to choose the library for image compression.
BufferedImage image = ImageIO.read(shape.getImageData().toStream());
// ...
// Compress image and set it back to the shape.
shape.getImageData().setImage("yourCompressedImage");
}
}
OoxmlSaveOptions saveOptions = new PdfSaveOptions();
saveOptions.setCacheBackgroundGraphics(true);
doc.save("Output.docx", saveOptions);
import com.aspose.words.*;
Document doc = new Document("Input.docx");
doc.cleanup();
NodeCollection nodes = doc.getChildNodes(NodeType.SHAPE, true);
for (Shape shape : (Iterable<Shape>) nodes)
{
if (shape.isImage())
{
// It's up to developer to choose the library for image compression.
BufferedImage image = ImageIO.read(shape.getImageData().toStream());
// ...
// Compress image and set it back to the shape.
shape.getImageData().setImage("yourCompressedImage");
}
}
doc.save("Output.docx");
import com.aspose.words.*;
Document doc = new Document("Input.docx");
doc.cleanup();
NodeCollection nodes = doc.getChildNodes(NodeType.SHAPE, true);
for (Shape shape : (Iterable<Shape>) nodes)
{
if (shape.isImage())
{
// It's up to developer to choose the library for image compression.
BufferedImage image = ImageIO.read(shape.getImageData().toStream());
// ...
// Compress image and set it back to the shape.
shape.getImageData().setImage("yourCompressedImage");
}
}
OoxmlSaveOptions saveOptions = new OoxmlSaveOptions();
saveOptions.setCompressionLevel(CompressionLevel.MAXIMUM);
doc.save("Output.docx", saveOptions);
import com.aspose.words.*;
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
Shape shape = builder.insertImage("Input.docx");
// Update page settings to crop the document to fit the size of the picture.
PageSetup pageSetup = builder.getPageSetup();
pageSetup.setPageWidth(shape.getWidth());
pageSetup.setPageHeight(shape.getHeight());
pageSetup.setTopMargin(0);
pageSetup.setLeftMargin(0);
pageSetup.setBottomMargin(0);
pageSetup.setRightMargin(0);
ImageSaveOptions saveOptions = new ImageSaveOptions(SaveFormat.DOCX);
doc.save("Output.docx", saveOptions);
