PDF settings

The following settings are available:

  • Best quality
    Select this option to retain the quality of the pictures or the page image. The original resolution of the source image will be preserved.
  • Balanced
    Select this option to reduce the size of the PDF file while keeping the quality of the pictures or page image at a reasonably high level.
  • Compact size
    Select this option to greatly reduce the size of the output PDF file. The resolution of the pictures and page image will be reduced to 300 dpi, affecting their quality.
  • Custom...
    Select this option if you want to specify custom image quality settings. In the Custom Settings dialog box, select the desired settings and click OK.

Create PDF/UA (requires OCR)

Protect documents with passwords

This option allows you to protect your PDF document with a password to prevent unauthorized opening, printing, or editing. Click the Settings... button and specify protection settings in the dialog box that opens:

  • Document Open password
    If your document has a Document Open password, users will be able to open it only after entering the password you specify. To set a password for your document:
    1. Enable the Restrict access with a Document Open password option.
    2. Type the password and confirm it.
      Disable the Hide characters option if you want the characters of your password to be visible in the Document Open password field.
  • Permissions password
    This password protects the PDF document from unauthorized editing and printing and prevents users who do not know the password from copying its content into another application. Users will be able to perform all of these actions only after entering the password you specify. To set this password:
    1. Enable the Restrict printing and editing with a Permissions password option.
    2. Type the password and confirm it.
      Disable the Hide characters option if you want the characters of your password to be visible in the Permissions password field.

      Next, select the actions you want to allow users to perform.
      • The Printing drop-down list contains options that allow or restrict printing  the document.
      • The Editing drop-down list contains options that allow or restrict editing the document.
      • The Allow copying text, images, and other content option allows users to copy content (text, pictures, etc.) from your document. If you want to prohibit such actions, make sure this option is not selected.
      • The Allow screen readers to read text option allows screen reader software to read text from the document when it is open. If you want to prohibit such actions, make sure this option is not selected.
  • Encryption level
    The Encrypt drop-down list contains options that encrypt password-protected documents.
  • 128-bit AES is a fairly strong encryption algorithm based on the AES standard.
  • 256-bit AES is a strong encryption algorithm based on the AES standard.

Select one of the options from the Encrypt drop-down list. All document contents encrypts the entire document, while All document contents except metadata leaves the document's data unencrypted and readable.

Delete objects and data

Enable this option if you don't want to preserve various objects contained in the PDF document, then click the Select... button to select which objects you don't want to keep:

  • Comments and annotations
    Notes, annotations, shapes, and text blocks will not be saved.
  • Links, media, actions, scripts, and form data
    Interactive elements will not be saved.
  • Bookmarks
    Bookmarks will not be saved.
  • Attachments
    Attached files will not be saved.

Use one paper size for all page images

If this option is disabled, the original paper size of the page images will be retained. Enable this option if you want to use a specific paper size in your PDF document.

Use MRC compression (requires OCR)

Selecting this option will apply the MRC compression algorithm, which greatly reduces file size and preserves the visual quality the image.

Searchable PDF settings

This group of options lets you decide what elements of your PDF document you want to save. Depending on how you are planning to use your document, select one of the following options:

  • Text and pictures only
    This option saves only the recognized text and the associated pictures. The page will be fully searchable and the size of the PDF file will be small. The appearance of the resulting document may slightly differ from the original
  • Text over the page image
    This option saves the background and pictures of the original document and places the recognized text over them. Usually, this PDF type requires more disk space than Text and pictures only. The resulting PDF document will be fully searchable. In some cases, the appearance of the resulting document may slightly differ from the original.
  • Text under the page image
    This option saves the entire page as an image and places the recognized text underneath. The text layer makes it possible to search the document and copy text, while the page images insure that the document looks virtually the same as the original.

Create bookmarks from headings

Select this option if you wish to create a table of contents from the document headings.

Create PDF tags

Select this option to add PDF tags to the output PDF document.

Apart from text and pictures, PDF files can contain information about the document structure, such as logical parts, pictures, and tables. This information is stored in PDF tags. A PDF file equipped with PDF tags may be reflowed to fit different screen sizes and will display well on handheld devices.

When saving texts in PDF, you can use either Adobe fonts or the Windows fonts installed on your computer. To specify the font set to be used, select one of the following items from the drop-down list:

  • Use predefined fonts
