User Guide
RGB/CMYK/Grayscale/Other
Specifies the type of color management for the output file.
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.
Note:
Higher resolutions, such as 2400 ppi, are suitable only for small page sizes (up to 6.826 inches or 173.380 milli­
meters).
Export PDFs as text
If you have a PDF version of a document, but you don’t have the original application file, you can export the text to
Rich Text Format (RTF), a standard for exchanging content between text-editing applications, or Microsoft Word
format. Images in the PDF are saved by default in JPEG format. The text file you obtain when you export a PDF to
RTF or Word format is not equivalent to the source file in the authoring application. Some coding information may
be lost in the conversion.
You can also export a PDF to plain text or accessible text. Accessible text follows the reading order preference selected
in the Reading preferences, and includes comments and form fields in its output. Accessible text also includes some
formatting, such as line breaks. Any alternate text in the document tags is used in place of images and figures. Plain
text follows the structure order of text in the document and ignores all artifacts and figure elements in the
conversion. Hard hyphens are preserved, and soft hyphens are removed.
1 Do one of the following:
• Click the Export button in the Tasks toolbar, and choose Word Document.
•
Choose File > Save As, and then choose a text format: Microsoft Word Document (*.doc); Rich Text Format
(*.rtf); Text (Accessible) (*.txt); or Text (Plain) (*.txt).

Output Format

options.
Use Colorspace
Specifies the color space. You can choose Color or Grayscale, or let the color space be determined
automatically.
Change Resolution
Downsamples images. If you do not select this option, images are created at the same resolution
as in the PDF.
Downsample To
Specifies the resolution for downsampling images. Images are never upsampled.
Export images to another format
In addition to saving every page (all text, images, and vector objects on a page) to an image format using the File >
Save As command, you can export each image in a PDF to an image format.
Note:
You can export raster images, but not vector objects.
