How to Batch Resize Images in XnView MP The conversion process runs through a utility wizard: Select Tools > Batch convert. When the batch-conversion tool launches, click the Add files button to add images. Advance to the Actions tab of the utility. Click Add Action then select the action to be performed. You'll see one of your images as a preview in the right pane. To resize, you'd click Add Action > Image > Resize. Set the options for the conversion wizard. Use a drop-down to auto-configure the settings, or configure them manually. In most cases, a preset will work, but you can optionally configure the image's height and width and select the fitting and reduction constraints. Advance to the Output tab and set your desired output rules. You can configure the output folder, the template for the filename, image-metadata options, and actions to complete after the export concludes. Click Convert to begin the batch. Saving Your Settings At any step in the process, click the little disk icon in the bottom left of the Batch Convert window to save your settings to a configuration file. Use the folder icon, or the drop-down menu next to it, to reopen those settings later.
