Saving and exporting PDFs
Last updated 9/30/2011
HTML or XML options
When you export a PDF file to HTML or XML format, any images in PDF are converted to JPEG format.
Encoding Refers to the binary values, based on international standards, used to represent the text characters. UTF-8
is a Unicode representation of characters using one or more 8-bit bytes per character; UTF-16 represents characters
using 16-bit bytes. ISO-Latin-1 is an 8-bit representation of characters that is a superset of ASCII. UCS-4 is a Universal
Character Set coded in 4 octets. HTML/ASCII is a 7-bit representation of characters developed by ANSI.
Use Mapping Table Default uses the default character encoding defined in mapping tables, which appear in the Plug-
ins/SaveAsXML/MappingTables folder. These mapping tables specify many characteristics of how the data is output,
including the following default character encodings: UTF-8 (Save as XML or HTML 4.0.1) and HTML/ASCII (Save as
HTML 3.2).
Generate Bookmarks Generates bookmark links to content for HTML or XML documents. Links are placed at the
beginning of the resulting HTML or XML document.
Generate Tags For Untagged Files Generates tags for files that are not already tagged, such as PDFs created using
Acrobat 4.0 or earlier. If this option is not selected, untagged files are not converted.
Note: Tags are applied only as part of the conversion process and are discarded after the conversion. This is not a method
for creating tagged PDFs from legacy files.
Generate Images Controls how images are converted. Converted image files are referenced from within XML and
HTML documents.
Use Sub-Folder Specifies the folder in which to store generated images. The default is Images.
Use Prefix Specifies the prefix added to the image file names if you have several versions of the same image file. File
names assigned to images have the format filename_img_#.
Output Format Specifies the final format. The default is JPG.
Downsample To Downsamples image files to the specified resolution. If you do not select this option, image files have
the same resolution as in the source file. Image files are never upsampled.
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
Advanced > 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.
