Image styles are used to display image fields in a particular format. Any entity such as content, media, and taxonomy, may have an image field.

Image styles enable you to:

• Define a set of transformations that can be applied to images automatically.

  These transformations help to ensure that images are displayed optimally across different contexts.

• Resize images to fit specific width and height requirements for consistency in presentation.
• Crop images to maintain specific aspect ratios, which is useful for maintaining visual consistency across different image displays.

• Apply various effects to meet specific design or branding needs.

  For example, desaturation for converting images to grayscale and watermarking for adding watermarks.
