## Menu and Toolbar

You will find the following buttons on the toolbar:

Open
Opens an existing image in the preview window.
Save
Saves the resized image, after letting you choose a location and specify a filename and format. Common formats like TIFF, JPEG, PNG, BMP, and TGA are supported; see Image File Formats for further details.
If you want to publish your images online, use the JPEG format to get the smallest file. For printing purposes, use TIFF, PNG, or BMP to maintain as much image quality as possible. TIFF is commonly used for professional printing.
Saving paletted images (indexed colors, such as GIF) is not supported. PhotoZoom Pro 4 will convert such images to grayscale or truecolor RGB.
New Batch
Batch processing offers the possibility to resize multiple images in one go (a batch). Say you need a thousand images to be resized to a certain size: thanks to the batch processing feature you do not have to open all images one by one, but instead you can simply select them all, specify the required size just once, and PhotoZoom Pro 4 will do the rest.
See the Batch Processing chapter for a more detailed explanation on how to use this feature.
Preview
Updates the preview in the preview window, based on the current settings. Note that when "Auto Preview" is enabled (which usually is the case), the "Preview" button will be disabled. Auto Preview ensures that an image is being updated immediately when a setting changes. Sometimes it can be useful to turn off auto previewing (for example on slow systems). To do so, you can deselect the "Auto Preview" option from the "View" menu. You can then use the "Preview" button when you want PhotoZoom Pro 4 to show you a preview based on the changes you made.
Preferences
Opens the Preferences window in which you can configure some settings.
Help
Opens the User Guide.
About
Shows information on the software and its creators, version number, registration info, website links, and licensing and copyright information.
