DocuFreezer Settings

DocuFreezer is a powerful desktop converter for Windows which can convert multiple documents, images, drawings, and other files at once to a convenient format – PDF, JPEG, PNG, TEXT, or TIFF. In this article, you will find a detailed description of DocuFreezer settings. 

Browsing for files and folders

If you want to add one or several files – click this button. The Add files dialog window appears. There you can browse for files for conversion. Besides, you can add RAR, ZIP, 7ZIP, and other types of archives. The program will convert files within the added archive(s).

If you want to browse for a folder with files – click this button. This way, you can add an entire folder with files. To set only certain file extension(s), change *.* macro (e.g., *.doc,*.docx) next to File types to add.

Managing file lists

Click this button to remove one or several selected items in the List of files 
Click this button to clear the List of files entirely 
Click this button to save all currently added files as a list for future use.
The list will be saved as a .flist file
Click this button to load a previously saved list of files (.flist file). You can also use an Excel spreadsheet (XLS, XLSX) with file paths, each listed on a separate line.

Output file settings in DocuFreezer

PDF

SettingDescription
Output file typeSelect output file format for your incoming files: JPEG, PDF, PNG, TEXT, TIFF
MultipageSet multipage option which will control the structure of output files: 
  • As in original file
  • Split into single pages
  • Merge into one PDF
Merge into one PDF option will combine multiple files into one – whether you have PDFs or other files as source files.
Combined fileSet filename of a multipage output file. Default name: "Combined.pdf"
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 a built-in OCR module
OCR languagesWith the previous feature enabled, you can select one or more OCR languages. As of version 3.2, English, French, German, Hebrew, Japanese, Portuguese, Russian, Spanish, Polish are available. Try to choose as few languages as possible at once in order to improve OCR accuracy.

JPEG

SettingDescription
Color spaceSet color space (color mode) for output JPEG files. You can select between: 
  • True color
  • Grayscale
QualitySet JPEG quality. You can adjust the quality within a range of 25-100%. Default value: 85%

PNG

SettingDescription
Color spaceSet color space (color mode) for output PNG files. You can select between: 
  • True color RGB
  • True color RGBA
  • Grayscale 
  • 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

SettingDescription
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. Note: the fewer languages are selected, the more accurate OCRing will be. 

TIFF

SettingDescription
Color spaceSet color space (color mode) for output PNG files. You can select between: 
  • True color RGB
  • True color RGBA
  • Indexed (256-colors)
  • Grayscale 
  • 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
CompressionSet 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.6
  • LZW
  • Jpeg
  • 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
MultipageSet multipage option which will control the structure of output files: 
  • As in original file
  • Split into single pages
  • Merge into one TIFF
Combined fileSet filename of a multipage output file. Default name: "Combined.tif"

File extension aliases

If you have files in supported format but with a non-standard file extension, DocuFreezer won't let you process these files. Still, there is a way to add and convert them. With the help of the File extension aliases tab, it is possible – just associate your files with an existing format. To do it:

  1. Check your file extension. For instance, if you have files like "Document.invoice", copy the extension "invoice";
  2. Go to File extension aliases and place a cursor next to the format you want to associate your files with;
  3. Add the file extension to the dropdown list.

Edit operations

You can add operations to be performed with your files during conversion via the Edit operations tab. Here you can make DocuFreezer insert a text or an image watermark. If you add two or more watermarks, you can control their vertical position by moving them up or down.
