Batch Conversion

Top  Previous  Next


Use the batch conversion tool, if you want to apply the same manipulation to multiple pictures. This operation is introduced in the Explorer by a Job-Wizard, which allows several types of Image Selection.


Supported conversions in the batch dialog:


Clipping: cut off edges, i.e. from scanned images
Adding text watermarks
Adding clipart watermarks
Adding borders
Adding shadows
SmartFlash image correction
SmartFix image correction
White Balance (careful: does not work for all images)
Color Balance (careful: does not work for all images)
Auto Exposure
Auto Color
Brightness, Gamma, Contrast, Saturation
Noise Reduction
Editing EXIF/IPTC data, in/decrementing date values
Convert file types (output format) and compress (see More options button)


Other batch conversions in the Explorer:


Encrypt images (see Mail Images)
Rotate images
Add GPS coordinates to images
Batch rename image files
Restore file creation dates (see Image Editor Options)
Burn on CD/DVD




To apply batch conversion to your images or image folders, follow these steps:


Activate the tool from the Explorer window.


Select multiple images using the Ctrl and Shift buttons.


Choose Tools > Batch Conversion


Uncheck Resample, if you just want to add watermarks or change the output format (filetype).


The button More options allows you to change many properties related to the selected filetype.




The dialog to the left shows the conversion options for the GIF filetype. You can change the color space, transparency, interlace factor and background color.


Define the output (destination) folder, or select Store in source folder, if you want to store the converted files along with the originals.

In this case, make sure you define a Prefix, so your original files are not overwritten!


Before applying the SmartFix, White Balance or Color Balance algorithms to your selected images, first preview some of the results in the Improve tab. Use the Display Original checkbox to see the exact result. (Without this checkbox, the preview uses the smaller thumbs for speed.) You can then zoom into and compare the Before/After images.


Note, that SmartFix is a lengthy procedure, and that you may want to press ESCAPE during the processing, if you find that you selected too many files at once.


How to correct EXIF / IPTC date values


Date parameters can be:


1. Date values of the form "12.11.2006 21:23:24"


2. Filedate tokes: "FileCreationTime", "FileModificationTime", "FileMinimumTime"


If you enter these tokens, the file dates are transferred to the corresponding EXIF/IPTC fields. This may become useful, if image files lost their EXIF data after image editing in programs outside of CodedColor.


FileMinimumTime is the smallest of the two others. Since the CreationTime designates the time, at which the file was copied to the hard disk, the ModificationTime can be closer (or equal) to the time the picture was taken by the camera.


3. Relative increments of the format [+/-]value[type], where type must be one of the following. Note, that month is m and minute is n:


d = day, m = month, y = year, h = hour, n = minute, s = second



Examples: +24h is the same as +1d, and it will increment the date by one day. The following example sets the EXIF field DateTimeDigitized to a fixed value, and corrects the IPTC field DateCreated by one hour:

The JPEG quality value is relevant for most batch operations, even if Size & Quality is not checked. This is due to the fact, that new images need to be created, except when you do simple EXIF/IPTC field changes. For an optimal quality/filesize ratio, or if you intend to overwrite your original images, make sure to use values around 94.


If you deselect the Output tab, then your original images will be overwritten. You should not do this, unless you only intend to change EXIF/IPTC fields.


The IPTC fields ObjectName, Caption/Abstract and Keywords cannot be changed via batch processing, because they are replicated from the corresponding Database fields Title, Description and Keywords in the Title and Annotations dialog. If you want to annotate several images at once, you have to select the thumbs in the Explorer before opening the annotation dialog.


Read here, how to assign keywords to several images at once.


When you save your annotations to the image, you may loose EXIF data from fields, that don't belong to the EXIF standard. If you have such fields in your images, make sure you don't overwrite the originals by selecting a distinct Destination folder or Prefix.
