Converting images to an image format
In addition to saving every page (text, images, and vector objects) to an image format using the File > Save As command, you can convert each image in an Adobe PDF file to an image format.
Note: You can export raster images, but not vector objects.
To convert each image in an Adobe PDF file to an image file format:
1.Choose Advanced > Export All Images.
2.In the Export All Images As dialog box, choose the image type for Save As Type (Windows) or Format (Mac OS). By default, the source file name is used as the file name with the image file type appended.
3. Click Settings.
4. In the Export All Images As Settings dialog box, select the file settings, color management, and conversion settings for the file type. (See Conversion options for JPEG and JPEG2000 format, Conversion options for PNG format, and Conversion options for TIFF format.)
5. For Exclude Images Smaller Than, select the smallest size of image to be extracted. Select No Limit to extract all images.
6. Click OK, and in the Export All Images As dialog box, click Save or OK.
