Enable Image Resizing

To allow image resizing, navigate to Configuration>Options>General>Image Resizing and set it to True. When enabled, large images will be resized on the user’s device prior to being uploaded.

Setting the Image Resizing Size

To specify a small, medium, large, extra large or custom size for the image resizing, navigate to Configuration>Options>General>Image Resizing - Size

Custom Image Size

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.
