With XnView you can resize image or apply effects and filters by opening and editing an image. Often you want to apply the same operation to several images. Below please find a description on how to apply an effect, filter, or any other operation on many files at once. You will use the "Batch conversion" of XnView to achieve this.
As an example for a batch conversion, here are the steps for resizing several image files to 50% of their original size:
1.) Select one or several files in the XnView browser
2.) Select "Tools > Batch Convert..."
3.) In the "Batch Convert" dialog, switch to tab "Transformation". There you will see two lists, on the left the list of available transformations, on the right the selected transformations. At first, the list of selected transformation is empty.
4.) Select transformation "Image > Resize", and add this transformation by pressing the "Add" button
5.) On the right side select the transformation "Resize". The process "Resize" has parameters which you can see on the bottom right. Here you select the "%" radiobutton, and then enter "50" for both width and height.
6.) Switch back to the tab "General".
7.) Specify the output directory for the converted files
8.) Choose the format for the converted files. The output file format may differ from the format of the original images. For example, you may wish to convert "jpg" to "gif" or "png".
9.) Confirm your choices in the "Batch convert" dialog with "Go".
XnView will convert all the selected files and save them in the output directory.
- If you simply want to change the format of the images (i.e., "jpg" to "gif"), you can leave out steps 3-6.
- In the dialog "Batch convert", you can add and remove files from the file list, if needed. The files may stem from different directories.
- A more detailed description of the Batch conversion can be found in the XnView Online help
in the chapter, "Using XnView > Multiple Image Convert".
