The general effects of selecting an option (for example, the number of bytes that would be removed from the file or the number of images that would be affected) is shown immediately to its right if nothing is shown, that type of data is not present and enabling the option would have no effect.

Note that this might affect the display of the PDF on other computers if a font used in the PDF is not present on another computer, a substitute font will be used to render the PDF.Įnable any of the following options, as desired.
Drop Embedded: Enable to remove any embedded fonts from the PDF. Combine identical indexed colorspaces: Enable to cause all images that use identical color spaces to reference a single instance of the color space in the PDF and remove the duplicates. Remove ICC Color Profiles: Enable to remove any embedded ICC color profiles International Color Consortium (ICC) color profiles define color spaces, data that characterizes a color input or output device, according to standards maintained by the ICC., which are generally only needed when printing PDFs, and replace them with their defined, alternate color spaces. Automatically reduce bit depth of compatible images: Enable to cause all images selected for conversion (above) to be analyzed to determine whether they can be converted to a smaller bit depth without introducing errors (for example, some images saved as "full color" would do just as well saved at "8-bit color" with a considerably smaller file size) and, if so, convert those images to the smaller bit depth type. In addition, enable or disable any of the following global image settings: Quality: Select the image quality ( high, medium or low) for JPEG or JPEG2000 images. Bit Depth: Select the color depth Number of bits used to indicate the color of a single pixel/dot. If this value is 0, all of the images in this category are already at a lower DPI than what is selected. The number of images that would be reduced by the selection is shown below the selection. 
Max DPI: Select the maximum number of Dots Per Inch (or “resolution”) to convert images to.For monochrome images, CCITT generally renders the higher fidelity and JBIG2 results in the smaller image sizes. Compression is based on wavelet technology and creates compressed images that generally look better than a JPEG file the compression mechanism is more complex, however, and therefore requires more computing power to display.

and JPEG2000 JPEG2000 is an update to the JPEG format. When an image is stored in this format, it will not retain all of the fidelity of the original source image, but it will produce a significantly smaller file than PNG. renders images of higher fidelity while JPEG JPEG is a lossy compressed graphics format that drops certain graphic information entirely in the save process.

The benefits to using this format are that the full quality of the image will be retained, yet the amount of information describing the image will be reduced, generally resulting in a smaller file size. The effects of this selection vary greatly according to the original image type, but for color images, generally PNG The PNG format is a lossless compressed format.
Convert to: Select the image type to convert images to. Settings are applied to all images in the category. Images are broken into four categories according to bit depth ( Full Color, 8-bit Color, Grayscale and Monochrome) and the number of images in a given category is shown below each heading as the Count. These values update as settings are changed use them to determine whether the selected configuration meets the file reduction needs. This is also where the values for the original File Size, the Estimated reduced file size and the percentage by which the document will be reduced are shown. It shows a breakdown of the PDF’s file size and can indicate where the most dramatic file reductions can be realized. Before beginning, however, consult the color-coded bar chart at the bottom of the dialog box. Reduction settings are divided among three tabs at the top of the dialog box. The Reduce File Size Custom Settings dialog box appears. 
Select a previously saved custom configuration set from the Edit Preset menu and click OK, then proceed to step 4 below.Ĭlick Edit. The leftmost setting has the highest image quality with the lowest amount of compression while the rightmost setting applies the highest amount of compression resulting in the greatest size reduction, though possibly at the expense of image quality.
Move the slider bar to the desired setting. Use one of these presets or use customized reduction settings to determine how the PDF will be compressed. Revu comes preloaded with several convenient Presets, pre-configured settings designed to balance document Quality with the amount of Compression. Go to Document > Process > Reduce File Size.
