Increases file size only slightly, unless the document uses CIDįonts, a font format commonly used for Asian languages. Prevents font substitution when readers view or print the file,Īnd ensures that readers see the text in its original font. Run Length compression produces the best results for images that contain large areas of solid black or white.Ī font can be embedded only if it containsĪ setting by the font vendor that permits it to be embedded. Group 3, used by most fax machines, compresses monochrome bitmaps one row at a time. Group 4 is a general-purpose method that produces good compression for most monochrome images. CCITT (Consultative Committee on International Telegraphy and Telephony) compression is appropriate for black-and-white images and any images scanned with an image depth of 1 bit. The Automatic (JPEG 2000) option is only available when Compatibility is set to Acrobat 6 (PDF 1.5) or later.Īre only available for monochrome bitmap images. The JPEG 2000 option is only available when Compatibility is set to Acrobat 6 (PDF 1.5) or later.ĭetermines automatically the best quality for color and grayscale images. It also provides additional advantages, such as progressive display. Like JPEG compression, JPEG 2000 compression is suitable for grayscale or color images. Is the international standard for the compression and packaging of image data.

ZIP compression can be lossless or lossy, depending on the Image Quality setting. Works well on images with large areas of single colors or repeating patterns, and for black-and-white images that contain repeating patterns. Because JPEG compression eliminates data, it can achieve much smaller files sizes than ZIP compression. JPEG compression is lossy, which means that it removes image data and may reduce image quality however, it attempts to reduce file size with a minimal loss of information. Is suitable for grayscale or color images. For most files, this option produces satisfactory results. Bicubic is the slowest but most precise method, resulting in the smoothest tonal gradations.ĭetermines the type of compression that is used:ĭetermines automatically the best quality for color and grayscale images. Uses a weighted average to determine pixel color, which usually yields better results than the simple averaging method of downsampling. Subsampling significantly reduces the conversion time compared with downsampling but results in images that are less smooth and continuous. The interpolation method you choose determines how pixels are deleted:Īverages the pixels in a sample area and replaces the entire area with the average pixel color at the specified resolution.Ĭhooses a pixel in the center of the sample area and replaces the entire area with that pixel color. All images with resolution above this threshold will be downsampled. Then enter a resolution in the For Images Above text box. To downsample color, grayscale, or monochrome images, choose an interpolation method-average downsampling, bicubic downsampling, or subsampling-and enter the desired resolution (in pixels per inch).

For example, if you are creating a PDF document of a map, consider using a higher image resolution so that users can zoom in on the map.ĭownsampling refers to decreasing the number of pixels in an image. You should also consider whether users need to magnify a page.
If you plan to print the PDF file at high resolution, check with your prepress service provider before setting compression and downsampling options. If you plan to use the PDF file on the web, use downsampling to allow for higher compression.
