If the output PDF file contains images, you can reduce its size using image compression.
To enable image compression, set the compress_images property to True. The GroupDocs.Viewer compresses all images in the file.
The image_quality property determines the compression ratio. It is a quality value in percent. 100% means original quality.
The following code snippet shows how to compress images in the file:
from groupdocs.viewer import Viewer
from groupdocs.viewer.options import PdfViewOptions, PdfOptimizationOptions
def reduce_image_quality():
# Load document
with Viewer("sample.docx") as viewer:
viewOptions = PdfViewOptions("reduce_image_quality/reduced_quality.pdf")
viewOptions.pdf_optimization_options = PdfOptimizationOptions()
viewOptions.pdf_optimization_options.compress_images = True
viewOptions.pdf_optimization_options.image_quality = 50
viewer.view(viewOptions)
if __name__ == "__main__":
reduce_image_quality()
sample.docx is the sample file used in this example. Click here to download it.
