The PDF Tab in the Formats Settings Dialog

Set the parameters for saving the recognized text into a PDF file:

Option name

Option description

Save Mode group
Text and pictures only The recognized text is saved as text, and the pictures - as pictures.
Page image only  Only the image is saved.
Text over the page image The entire image is saved as a picture. Text areas are saved as text over the picture.
Text under the page image The entire image is saved as a picture. The recognized text is put under it. This option is useful if you export your text to document archives: the full page layout is retained and the full-text search is available if you save in this mode.
Retain text and background color Set this option if you want the original background and character color to be retained.
If the Text under the page image mode is on, text and background color is saved automatically.
Replace uncertain words with image If you save your document in the Only text and pictures or the Text over the page image modes, you may have uncertainly recognized words replaced with their images. To do it, set this option. 
Font use mode
  1. Use Acrobat Reader standard fonts - PDF file refers to the standard system fonts Times, Helvetica and CourierNew.
  2. Refer to Type 1 fonts -  only references to Type 1 fonts are registered in the PDF file, the fonts themselves aren't embedded. Fonts referred to by the PDF file must be installed and available at Adobe Type Manager.
  3. Embed Type 1 fonts - the Type 1 fonts are embedded into the PDF file.


  1. In the Refer to Type 1 fonts mode only references to the fonts in use are registered in the PDF file (the fonts themselves are not actually embedded in the PDF file as they are in the Embed Type 1 fonts), so the PDF file occupies less disk space than the same file saved in the Embed Type 1 fonts mode. 
  2. Saving in the Embed Type 1 fonts mode enables other users to view, edit and print the document set in the original fonts even if these fonts are not installed on their computers.
Type1 fonts (button) Opens the Type 1 fonts settings dialog. The Type 1 fonts to set are serif, sans serif, and monospaced. These fonts are used for saving documents in a non-latin code page.
Reduce picture resolution to

Sometimes you may want to reduce the image resolution. For example, PDF files are usually viewed in a browser, so there is no sense to save high-resolution pictures in such files. So, you may reduce the image resolution (so reducing the PDF file size) without actually loosing the visual image quality: enter the necessary resolution value in the Reduce picture resolution to field.


  1. If you enter a higher resolution value that the source one in the Reduce picture resolution to field, this value will be ignored; the pictures will be saved using the source resolution.
  2. Usually, the default value of 150 dpi is suitable.
  3. If a PDF file has been added to the batch, when exporting it to PDF, HTML, RTF, DOC, Word XML or PPT formats the resolution of pictures will not exceed 300 dpi.
JPEG quality

When you save an image in JPEG format, the so-called "quality loss" algorithm is used to compress the image, i.e. the compressing technology is bases on averaging the groups of pixels, so that a whole region is saved as a single number and not as a big number of numbers that describe each pixel. The value specified in the JPEG quality field allows to set the desired quality of the image. You may specify a value in the range 1 - 100 (the default is the average value of 50).

The higher the value you specify in this field, the higher will be the quality of the image you save. The size of the image is also affected by this value: the higher the value, the larger *jpg file you get. In order to tune the best proportion size/quality, try to save the image with different JPEG quality value, and then open them in an image viewing application.
