	Output Location	Choose an output location from the options: Remove/replace original files: this option overwrites your original files. Same as source folder: pastes the resized files in the folder they originated. Specific folder: use the folder icon to navigate to a specific folder for the output files. Create subfolder: with an output location selected, check this checkbox to create a subfolder for your resized images. Enter a name in the box. This is useful if you are making multiple batch resizes to specific dimensions. You can save your resized files in separate folders.
	File options	Choose your file options for overwriting existing files. Choose whether to preserve certain file information when resizing. Choose your JPEG Compression options, find out more in the JPEG Options topic. Choose your resample type from the following options: Lanczos: produces the sharpest images, but may also introduce some ringing artifacts. Bell: smoothes the image. Bicubic: produces good results with photo-realistic images and with images that are irregular or complex. Uses interpolation to minimize the raggedness normally associated with image expansion. Box: displays considerable tiling or jaggies (jagged edges) when you resize an image. B-spline: produces smooth transitions, but may cause excessive blurring. ClearIQZ: slower than Bicubic and Lanczos, but produces the best results when enlarging photos, especially those of people. Mitchell: produces smooth transitions when enlarging photo-realistic images. This filter is good compromise between the ringing effect of Lanczos and the blurring effect of other filters. Triangle: produces good results for image reduction and enlargement, but displays sharp transition lines.
