USING ACROBAT X PRO 127 Saving and exporting PDFs If you want to use the same settings every time you convert PDFs to a particular format, specify those settings in the Preferences dialog box. In the Convert From PDF panel, select a file format from the list and click Edit Settings. (Click the Default button at any time to revert to the default settings.) More Help topics "Convert PDFs to Word, RTF, spreadsheets or other formats" on page 130 "Export images to another format" on page 131 "Export selections to another format" on page 131 Adobe PDF options You can resave PDFs as optimized PDFs, using settings in the PDF Optimizer dialog box. The PDF Optimizer lets you change the compatibility version of your PDFs so they can be viewed using older versions of Acrobat or Reader. When you change the compatibility setting, newer features may be unavailable in the PDF. For an explanation of each compatibility setting, see "PDF compatibility levels" on page 89. Image conversion settings JPEG and JPEG 2000 options If your PDF contains a collection of images, you can export them individually as JPEG, PNG, or TIFF files by choosing Tools > Document Processing > Export All Images. Note that the options available depend on whether you are exporting a document to JPEG or JPEG 2000. Grayscale/Color Specifies a compression setting that balances file size with image quality. The smaller the file, the lesser the image quality. Tile Size Divides the image being compressed into tiles of the given size. (If the image height or width is not an even multiple of the tile size, partial tiles are used on the edges.) Image data for each tile is individually compressed and can be individually decompressed. The default value of 256 is recommended. This option is available only for JPEG 2000 format. Format Determines how the file is displayed. Available only for JPEG format. • Baseline (Standard) Displays the image when it has fully downloaded. This JPEG format is recognizable to most web browsers. • Baseline (Optimized) Optimizes color quality of the image and produces smaller file sizes but is not supported by all web browsers. • Progressive (3 scans-5 scans) Downloads the image first as a low-resolution image, with incremental quality improvements as downloading continues. RGB/CMYK/Grayscale Specifies the type of color management to be applied to the output file and whether to embed an ICC profile. Note: If you use the Save As or Export All Images command on a PDF that contains JPEG and JPEG 2000 images, and export the content to JPEG or JPEG 2000 format, the resulting image may look different when opened in Acrobat. This can happen if the images have a color profile included at the page level but not inside the image data. In this case, Acrobat cannot bring the page-level color profile into the resulting saved image. Colorspace/Resolution Specifies a color space and resolution for the output file. You can let Acrobat determine these settings automatically. To convert color images in the file to shades of gray, choose Grayscale. Last updated 10/11/2011
