Filters allow you to apply special effects to images and selections.
FILTERS modify images and selections in various ways giving you access to various ways. The sample image to the left will be modified by all the available filters in Pixlr Editor Filter Menu to give you a feel for what filters can do. Some filters have settings. The settings used will be annotated for your information. I used the default setting for most filters but changed changed settings where I thought it would better illustrate the filter's properties The sample to the left is 750 x 1000 pixels (px).
