    Hello,

    I'm trying to upload an image after editing it the file size increase and bit depth increase,

    is there any solution to keep the bit depth as it is and reduce file size.

    Thanks.

    Hi johny,

    I am afraid that currently RadImageEditor does not provide an option to control the quality and/or DPI of the resized/cropped/saved images. The graphics core of RadImageEditor is the .NET standard GDI+ library and the image scaling algorithm, which is used during the resizing/cropping is called Bicubic Interpolation. Unfortunately there is no known way to resize an image without distorting its quality at all, but currently the Bicubic Interpolation is preserving the image's information in the best possible way. This is why the image could be with different size after the interpolation, depending on its quality before the resizing/cropping.

    The only possible option I can suggest you at this moment is to submit a feature request for such improvement so our developers will research the options for its implementation (if possible) for a future version of the controls:
