How to batch resize images

To batch resize images, open File Studio's image Resize tool, drop in all your images or a whole folder, set exact dimensions or a maximum width and height that keeps the aspect ratio, and click Resize. File Studio processes the whole batch locally and saves resized copies, leaving your originals untouched.
