When the Image Resizing - Size option is set to Custom, further options need to be configured.

Custom JPEG Quality

If desired, a compression level can be set when uploading a JPEG file format by navigating to Configuration>Options>General>Image Resizing - Size>Custom JPEG Quality

The default value for this setting is 0.9 so changing this to a value between 0 and 1 is optional. Values above 0.9 will result in minimal compression. Values below 0.6 may result in visibly degraded image quality.

To set the image height for a custom image size in pixels, navigate to Configuration>Options>General>Image Resizing - Size>Custom Maximum Height.

To set the image width for a custom image size in pixels, navigate to

Configuration>Options>General>Image Resizing - Size>Custom Maximum Width

Images will be scaled proportionally to fit within the specified target width and height.
