  4. 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.

  5. 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.

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.
