Saving in PDF
PDF is a widely used document format. PDF documents appear the same on different computers, can be protected with passwords, and are well suited for storage in electronic archives.
- Click the arrow next to the Save button on the main toolbar and then click Save as PDF Document…. If the format that you need is not displayed in the list, click Save in Other Formats… and then select the desired format from the Save as type drop-down list. Alternatively, on the File menu, click Save Document As and then click PDF Document.
Tip: Additional saving options are available in the Options dialog box: click Tools > Options…, click the Save tab, and then click the PDF tab.
The saving options on this tab are grouped into the following categories:
Default paper size
Choose the paper size to be used for saving in PDF format from the drop-down list.
Depending on how you are planning to use your electronic 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 is 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 image as a picture and places the recognized text underneath. Use this option to create a fully searchable document that looks virtually the same as the original.
- Page image only
This option saves the exact image of the page. This type of PDF document will be virtually indistinguishable from the original but the file will not be searchable.
Depending on the save mode you select, some of the following options will become available:
- Keep text and background colors
Select this option to retain the font color and background when saving in PDF.

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 encoded 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.
- Compress images using MRC
Select this option to retain the visual quality of the text and the pictures in a highly compressed document.
- Apply ABBYY PreciseScan to smooth characters on images
Select this option to smooth characters on the document using ABBYY's PreciseScan technology, making them less pixelated.
The resulting file may be quite large if your text contains a lot of pictures or if you choose to save the page image together with the recognized text. To adjust the size of the resulting file and the quality of the pictures, select one of the options from the Image settings drop-down list:
- Best quality (source image resolution)
Select this option to retain the quality of the pictures or the page image. The original resolution of the source image will be preserved.
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 obtain a small-sized PDF file. The resolution of the pictures and page image will be reduced to 300 dpi, affecting their quality.
Select this option to choose your own picture and page image settings in the Custom Settings dialog box.
Tip: If you do not want to keep the pictures in the recognized text, make sure that the Keep pictures option is not selected.
