Configuring settings
To open the settings window, click the Settings button on the top menu:
Output file settings*
Depending on the output filetype selected, these settings vary.
| Output file type | Select output file format for your incoming files: JPEG, PDF, PNG, TEXT, TIFF |
| Multipage | Set multipage option which will control the structure of output files: As in original fileSplit into single pagesMerge into one PDF |
| Combined file | Set filename of a multipage output file |
| Make PDF searchable (OCR) | Recognize text from images or image-based files. This feature allows extracting text into searchable PDF or plain TXT file(s) via built-in OCR module. |
| OCR languages | With the previous feature enabled, you can select one or more OCR languages. As of version 3.1 of DocuFreezer, English, German, Hebrew, Japanese, Russian, Spanish are available. Try to choose as few languages as possible at once in order to improve OCR accuracy. |
JPEG
| Color space | Set color space (color mode) for output JPEG files. You can select between: True color Grayscale |
| Quality | Set JPEG quality. You can adjust the quality within a range of 25-100%. By default is set to 85% |
PNG
| Color space | Set color space (color mode) for output PNG files. You can select between: True color RGBTrue color RGBAGrayscale Monochrome The difference between RGB and RGBA is opacity (transparency). RGB stands for a 3-channel format containing data for Red, Green, and Blue whereas RGBA is a 4-channel format containing data for Red, Green, Blue, and Alpha. Alpha channel allows saving transparency. The difference between Grayscale and Monochrome is that grayscale mode preserves different shades of gray, and monochrome preserves only black & white colors. See illustration |
TEXT
| OCR (Optical Character Recognition) | Enable this feature to batch convert scanned documents or images to plain text (TXT) via OCR |
| OCR languages | With the previous feature enabled, you can select one or more OCR languages. As of version 3.1 of DocuFreezer, English, German, Hebrew, Japanese, Russian, Spanish are available. Try to choose as few languages as possible at once in order to improve OCR accuracy |
TIFF
| Color space | Set color space (color mode) for output PNG files. You can select between: True color RGBTrue color RGBAGrayscale Monochrome The difference between RGB and RGBA is opacity (transparency). RGB stands for a 3-channel format containing data for Red, Green, and Blue. RGBA is a 4-channel format containing data for Red, Green, Blue, and Alpha. Alpha channel allows saving transparency. The difference between Grayscale and Monochrome is that grayscale mode preserves different shades of gray, and monochrome preserves only black & white colors. See illustration |
| Compression | Set level of TIFF compression algorithm to reduce output file size. You can manually select between: -Default- Modified Huffman RLE/MH Group3 Fax/T.4 Group4 Fax/T.6LZWJpeg Flate You can keep default compression, and it will adapt to your input files depending on their type and color mode. Group3 Fax/T.4 is better for grayscale or monochrome documents and CAD drawings. Jpeg is better for photographs and high-quality images. Flate is better for pictures in general |
| Multipage | Set multipage option which will control the structure of output files: As in original fileSplit into single pagesMerge into one PDF |
| Combined file | Set filename of a multipage output file |
Advanced settings
| Overwrite existing files | Check this option to let DocuFreezer overwrite converted files if they have the same filename |
| Split worksheets (Excel, CAD) into multiple files | Check this option to split output Excel and AutoCAD (DWG, DXF) worksheets into separate files if they have numerous sheets |
| Convert attachments | Set how DocuFreezer handles file or email attachments (e.g., for PDF Portfolio or Outlook message files):Ignore – attachment is ignored, only the file is processedSeparate – both file and attachment are processed, they are saved as separate filesCombine – both file and attachment are processed, they are saved as a single file |
| Rasterization resolution | Set DPI (Dots Per Inch) which defines resolution and image quality. DPI can be set in a range between 72 to 2400. 300 DPI is suitable for standard quality prints e.g., text documents. 600 or higher is good for high-quality images or photos. Generally, we don't recommend setting DPI lower than 300 (the printout may have low quality) or higher than 1200 (processing may take much time) |
| Page range | Set one, several, or a range of pages to process. This way, the program converts only specific pages of all documents within a session. Using this option, you can also extract certain pages from multipage documents (and save them separately or as a multipage file) |
Other even more advanced settings can also be configured via the Ini File Editor.
