@zyx,

You can convert Word DOCX to Images and then increase the quality of JPEG images by using the following options:

Document doc = new Document("C:\\Temp\\b82091828ba6f1a7e6011606dc468b77.docx");

ImageSaveOptions options = new ImageSaveOptions(SaveFormat.JPEG);
options.setImageBrightness(0.7f);
options.setImageContrast(0.7f);
options.setJpegQuality(100);
options.setUseAntiAliasing(true);
options.setUseHighQualityRendering(true);
options.setResolution(300);

for (int i = 0; i < doc.getPageCount(); i++) {
    options.setPageSet(new PageSet(i));
    String filename = "C:\\Temp\\231328\\2\\page " + i + ".jpg";

    doc.save(filename, options);
}
