Advanced Settings

2TIFF offers a wide range of advanced settings to customize your file conversion process. You can set custom filenames, adjust output file quality, reduce file sizes, skip specific files using masks, handle attachments, and more.

Task processor

Timeout
Default: Response timeout: 5 min; Task processing timeout: 100 min

Set a time limit for processing each individual file. Once this time limit is reached, 2TIFF will proceed to the next file. It is not recommended to modify this parameter unless you are certain or have received advice from our support service.

Memory leaks limit
Default: 512 MB

Set a limit on the random-access memory allocated for 2TIFF's work. If the amount of memory leaks exceeds a certain threshold, the program engine will automatically restart without any interruption. This allows 2TIFF to process any number of files per session without encountering any issues.

Restart after jobs number
Default: 4096 jobs

Automatically restart the program engine after a specific number of jobs.

Enable custom scripts
Default: Yes

Custom Python scripts can be used to modify the default behavior of the program. By default, these scripts are enabled. Disabling them will restore the program to its default state.

Display progress bar for each fil
Default: Yes

By default, the program shows the status of each file being processed. Disabling this setting may enhance performance when dealing with small files, but it will remove the progress bar indicators.

Raster image engine
Default: GDIPlus

Set a raster image engine. You can choose between GDIPlus and Graphic Processor. Please do not modify this parameter unless advised by our support service.

Rebex MHT to PDF engine
Default: AsposeWords

Select the main component for converting MHT to PDF. Please do not change this parameter unless instructed by our support service.

Extract PDF attachments engine
Default: PatagamesPdfium

Set the main component for extracting PDF attachment(s). You can choose between PatagamesPdfium, ABCPDF, and Acrobat. Do not modify this setting unless instructed by our customer service.

Extract from email attachments engine
Default: Rebex

Set the main component for extracting email attachment(s). You can choose between Rebex and Outlook. Do not modify this setting unless instructed by our customer service.

Get file list from Excel file engine
Default: AsposeCells

Choose the primary component when using an Excel file (XLS/XLSX/CSV) for loading a list of files to the program for further processing. Excel or AsposeCells can be selected. Only change this setting if advised by our customer service. 

OCR engine
Default: TesseractOCR

Set the primary component for OCR processing. You can select Acrobat as an OCR component if you have Adobe Acrobat installed.

Disabled helpers
Default: Acrobat

Disable specific components that are used by the program to process certain types of files. It is not recommended to modify this parameter unless you are certain or have received advice from our support service.

Kill hanging processes
Default: Yes

The program may use the API of Microsoft Office applications during its operation. When this option is enabled, it will terminate background processes that were started by third-party software, such as Microsoft Word, Excel, and others, if they are no longer needed.

Use internal engines whenever possible
Default: No

Enabling this option will prompt the program to prioritize its internal (built-in) engines for file processing. If that is not possible, external components will be utilized.

Files and folders

Keep source files available for editing
Default: No

Enabling this setting will allow you to open and edit the source files while they are being processed by the program.

Temp folder
Default: %TEMP%

Change the folder where temporary files created by 2TIFF are located. By default, it is "C:\Users\[User]\AppData\Local\Temp".

Password list
Default: none

Enter the password for the source file(s) to batch convert password-protected documents. If you have more than one file secured with passwords, input several passwords, each on a separate line.

Restore subfolders
Default: Yes

Keep the same subfolder structure as in the input folder (if a folder is specified as the source).

Recurse subfolders
Default: Disabled

Enable or disable subfolder recursion. When enabled, the program will process files from subdirectories as well. To exclude specific subdirectories, you can optionally enter their paths in the Exclude certain subfolders field.

Existing file action
Default: Create new file

Define what the program should do if the output folder already has a file with the same filename: Create new file, Overwrite, Skip.

Destination file password
Default: none

Enter a password to protect the converted files. The password protection will be applied to all successfully processed files.

Keep output files on any error
Default: Yes

Define the program's behavior when it encounters an error, such as when a watermark file is missing. If set to No, the program will not save files in the output folder if an error occurs.

Output filename template
Default: {*SrcFilename}{*WorksheetName}{*SrcFileMPageNo}.{*DstFileExt}

Modify the output file name template using macros and/or arbitrary text. The default output name is: {*SrcFilename}{*WorksheetName}{*SrcFileMPageNo}.{*DstFileExt}.

• {*srcfilename} – source file name;
• {*worksheetname} – worksheet file name (for Excel or CAD files);
• {*srcfilempageno} – source file page number ("M" stands for multiple pages, this macro does not add page number "1" to single-page files);
• {*dstfileext} – destination file extension.

Click the {=} icon to add other built-in macros, such as regular expression of source file name, date/time, source file's number of pages, and more.

You can combine macros with your own text, including spaces and dots. For example: 

Item {*listitemno} {*srcfilename}.{*dstfileext} | Created: {*date(dd.mm.yyyy)}

Note: macro names are not case-sensitive. That means, both {*dstfileext} and {*DstFileExt} will work the same way.

Keep source files' original date/time
Default: No

With this option enabled, you can save the source files' properties and keep them in the converted files' properties: last write (last modified) time and date.

Exclude files by mask
Default: ~$*.*, *.db, desktop.ini

Exclude certain types of files that are not wanted for processing. To exclude files with a specific file extension, add them to the dropdown list, each on a separate line (after ~$*.*, *.db, and desktop.ini). File extensions should be added in the following format: *.[file extension]

Page layout

Rasterization resolution
Default: 300 dpi

Set the DPI (Dots Per Inch) to define the output image resolution. The resolution can be set within the range of 54 to 16384.

A DPI of 300 is suitable for standard quality, such as text documents. For high-quality images or photos, a DPI of 600 or higher is recommended. It is generally not recommended to set it lower than 300 (as the output file may have low quality) or higher than 1200 (as processing time may increase).

Use rasterization anti-aliasing
Default: Yes

Use a rasterization algorithm with anti-aliasing to improve the quality of the image. Anti-aliasing helps to smooth the edges of an image, making the transition more gradual and reducing the appearance of jagged pixels.

Attachments

Convert attachments
Default: Separate

Specify how the program should handle files with attachments, such as PDF Portfolios or Outlook email message files:

Option	Effect
Ignore	Skip attachment(s) and convert only the main document
Separate	Save each attachment and the main document as separate files
Combine (attachments after main doc)	Convert the main document and append its attachment(s) after it
Convert attachments only	Skip the main document and process only attachment(s)
Combine (attachments before main doc)	Convert the main document and prepend its attachment(s) at the beginning

Sort attachments
Default: Name

Select how file attachments should be sorted in the output folder: 

Attachments of unknown types action
Default: Ignore

Specify the action to take for unrecognized attachments. When this setting is set to Ignore, the program will skip file attachments if their format is not supported or cannot be recognized. You can change it to Replace with placeholder (refer to the next setting Attachments placeholder template to define its appearance) or Try to process.

Attachments placeholder template
Default: Filename

Configure placeholder(s) that should be inserted instead of unknown attachments (refer to the previous setting). Attachments will be replaced with a blank-page file with the original filename (Filename). You can choose your own file (Browse for file) or create a custom template (-Open Cover page designer-) as an alternative.

Include attachments by file mask
Default: *.*

Use an expression that allows converting only certain attachments by mask. For example, type *.pdf to convert PDF attachments only. Or enter attachment.* to convert only files containing the word "attachment" in the filename. You can add one or several masks at the same time (each on a separate line).

Exclude attachments by file mask
Default: none

Use an expression that restricts processing of certain attachments by mask. You can add one or several masks at the same time (each on a separate line). For example: *.docx

Document converting settings

Page range
Default: All pages

Set page range by selecting all pages or a specific page range.

To choose certain pages or a specific page range, type in the desired page numbers and/or ranges separated by commas. For example: 1,3,5-10,25. To select pages from the end of the document, use the syntax last (last1 for penultimate page, etc.). For example: last2,last1,last

Skip repeated pages
Default: No

This feature helps you avoid converting the same page multiple times. For example, if you specified overlapping page ranges.

Save metadata
Default: none

Save metadata from the source files such as EXIF, IPTC, XMP and keep it in the output files.

Save ICC profile
Default: No

Save the ICC color profile in the output file if it exists in the source image file.

Grayscale
Default: No

Set the color mode in the output file to grayscale (in shades of gray).

Convert engine(s)
Default: none

Enter the name(s) of the specific file conversion engines to change their priority. Do not modify this setting unless instructed by our customer service.

OCR

OCR languages
Default: none

This setting is used for OCR (Optical Character Recognition). Select the language or languages that are present in your source files. To achieve better results, only select the languages that are actually used in your source files.

Post processing

Successfully processed files
Default: None

Choose an action to perform on the successfully converted files:

• Copy to folder
• Move to folder
• Delete files
• None

Files that failed to process
Default: None

Select an action to be performed with files that failed to convert for some reason:

• Copy to folder
• Move to folder
• Delete files
• None

Blank pages

Remove blank pages
Default: No

Enable/disable automatic detection and removal of blank pages during processing. Sometimes documents may contain blank pages (usually at the end of a document). The program can detect such pages and remove them. 

Min pixels quantity threshold
Default: 0.5%

Set the minimum number of pixels per page as a tolerance threshold to determine whether a page has colors other than white.

Min channels difference threshold
Default: 4%

Set the minimal difference of R, G, and B channels' values as a tolerance threshold to determine whether a page has colors other than white.

Output formats

TIFF

Multipage
Default: As in original file

Set the multipage option to control the structure of the output TIFF files:

• As in original file
• Split into single pages
• Merge into one file

The Split into single pages option creates a separate file for each page, regardless of whether the source files are multi-page or single-page. The Merge into one file option combines all files from the source into one multipage document. 

If you choose the Merge into one file option, you can refer to the Combined file setting to specify the filename for the output TIFF file.

Page index to insert
Default: -1

When using Multipage: Merge into one file, the program adds new files to the end of an existing document. However, you can also add them to the beginning (0) or insert them somewhere in between the document (e.g., 5 – to place new files after page 5). The default value is "-1".

Combined file
Default: Combined.tif

Set filename of the resultant multipage output file when Multipage: Merge into one file option is used. Default name: "Combined.tif"

Other settings 

The remaining settings in this section control the quality of output TIFF images:

• Pixel type (color space)
• Flate compression level
• Quantize colors
• Quantize quality
• Alpha threshold
• Quantize alpha channel
