ZIP is the better choice for illustrations with large areas of solid, flat color, or patterns made up of flat colors. In general, JPEG and JPEG 2000 compressions give better results on images like photographs with gradual transitions from color to color. Compression: Reduces file size by eliminating unnecessary pixel data.Downsample: Use options 'DownsampleMode', 'MaxResolutionLimit' and 'TargetResolution' to reduces file size by lowering the resolution of images, which involves merging the colors of original pixels into larger pixels.The image compression settings allow you to set options for color, grayscale, and monochrome image compression, and image downsampling. Our EdgePDF (asp.net pdf viewer and editor web control) has implemented anĪSP.NET PDF document compression solution based on the above functionsĬ#: Reduce a PDF file size by image compression These items include elements that are obsolete or unnecessary for your intended use of the document. Document Clean Up: Allow you to remove useless items from the entire PDF document using C#.Discard User Data: Allow you to remove, delete any personal information that you don't want to distribute or share with others.Selecting an object removes all occurrences of that object within the PDF. You can discard objects created in PDF reader, editor applications, such asĮdgePDF, and Acrobat. Discard Objects: Allow you specify objects to remove from the PDF file.The disadvantage is that image resources pixel point might be lost. Since images are usually or large size, images size reducing can help to reduce PDF file size effectively.

Image Compression: Allow you set options for color, grayscale, and monochrome image compression, and image downsampling.We can use several methods to optimize PDF: In most situations, the default settings are appropriate for maximum efficiency, saving space by compressing images, and removing objects, user data from the pdf file that are no longer used. Whether you apply all of these settings or only a few depends on how you intend to use the PDF files and on the essential properties a file must have.

NET SDK, class PDFOptimizer provides many settings for reducing the size of PDF files.
