Batch conversion – all marked files will be processed according to image processing properties. New files will be created into target directory. New files can be created with or without renaming (see below).

Rename and copy file only – all marked files will be copied into target directory. All image processing properties will be ignored. Files can be copied with or without renaming (see below), target file extension can not be changed.

Remove from list – all marked files, which has been processed, will be removed from filelist after batch processing is finished.

Delete source file - all marked files, which has been processed, will be removed from filelist and corresponding source files will be deleted from hard disk after batch processing is finished (practically, source files will be moved to Window's trash, so they can be restored, if checkbox has been checked accidentally).

Do not use File Rename Editor – output files will not be renamed. However, file extensions can be changed, if "Batch processor" mode is active.

Use File Rename Editor - output files will be renamed according to Rename Editor settings. The Rename Editor consists of 3 fields for filename and 1 combo box for extension. For renaming, you can enter a name pattern for new names (first and third fields) and the starting index for numbers (second field). You can use leading null(s) to specify how many digits you wish to be in output filename. For example:

"ABC-" "001" "-DEF" produces files "ABC-001-DEF", "ABC-002-DEF"... "ABC-010-DEF" etc.

"ABC-" "1" "-DEF" produces files "ABC-1-DEF", "ABC-2-DEF"... "ABC-10-DEF" etc..

First and/or third fields can be empty:

"ABC-" "001" " " produces files "ABC-001", "ABC-002"... "ABC-010" etc..

Output format properties

Some advanced options may be set for JPEG, PBM, PGM, PPM and TIFF output formats. For JPEG files you can use target Quality/size ratio or Size restriction mode.

Quality/size ratio. This mode produces output JPEGs with same compression ratio (same quality), but target file sizes will be different for each output file, especially, if source files are of various sizes. Desired quality/size ratio can be set with the scrollbar. You can view the target file size for selected file depending on scrollbar position, if Check size box is checked.

Size restriction. In contrast to the previous mode (above), this mode produces output JPEGs with approximately same target file size. In this mode, the compression ratio (quality) will be calculated for each file. It is very useful (especially when preparing files for internet uploading or forwarding to a client for “preview”), but obviously, you can produce output files with varying quality. For example, you have 2 source files. The first a 55 KB file, the second a 500 KB file. You set output file size restriction to 50 KB. Both files will be created at 50 KB. With the first file, the source and output file sizes will be roughly equal, therefore no quality loss. The second file will be reduced 10 times (500 KB -> 50 KB) therefore second file will lose some quality.
