Batch Conversion

	Click on the File menu, select Batch Conversion. A dialog opens. The right side of the box allows you to select a directory from which the files to be converted will be taken. Use Look in and File name to narrow down the search; use Files of type to limit the search to one type of file, such as jpg. On the bottom of the right side is the box for selecting the output directory: the one where the converted images will be stored. For best results, this should be a different location than the one from which the images are taken. If you change the type of image during conversion, the same directory may be used. If you don't have the full path for this directory, click the Browse button to find it. When you have selected a directory with Browse, click the Use dir button. To the right of Output directory is a button for Advanced Options. Click to open a dialog that allows many special operations to be applied to the images during conversion. These options all work much like their versions on the Image menu. The options are: Resize, Change color depth, Horizontal flip, Vertical flip, Rotate left, Rotate right, Convert to greyscale, Negative, Sharpen, Gamma Correction, Contrast, and Brightness. Check any or all you want to use, then click OK. To exit without making any selections, click Cancel. Select the files you want to convert. In the box above (still on the right side,) click the file names. If you have a large range of files to choose, click the first. Move the mouse to the last file in the group (use the horizontal scroll bar, if necessary,) hold down the Shift key on the keyboard, and click. The entire range will be selected. To choose individual files, hold down the Ctrl key and click each file name with the mouse. On the left side of the dialog, click the Add button. The files will be added to the box at left. These are the files that will be converted. If you like, you can click one file name at right, then the Add button. This can be repeated as many times as needed. Click the Add all button to select every image in the directory. Remove and Remove all perform the exact opposite function: they take chosen files back out. To use Remove, first click a file name or range of files in the box at left, then click Remove. At bottom left is a box for selecting the Output Format of the files. This works just like choosing the output type for Save and Save As. The Options button lets you choose from various operations to perform on the images, also just like their Save and Save As versions. These options are fully explained here. When all files and options are chosen, click the Start button to begin the conversion. A box will appear, showing the progress of the conversion. If you need to halt the operation, click the Stop button. As the conversions are made, IrfanView shows the progress in the dialog box, including any errors that occur. When the process is done, click the Exit button to close the dialog. Batch conversion may also be performed from outside IrfanView, using a command line option. For a helpful reminder of many of the functions in the Batch conversion dialog, click the ? in the upper right corner of the box, point the mouse at an item in the box, and click again. A message will appear to tell you what that item is for. When you are finished converting files, click the Cancel button to exit the dialog. You may also click this at any time before the conversion process starts. Another way of exiting is to click the X in the upper right corner of the box.
