No, you can't change the file size using DOC to Image Converter. You can change only the dots density per inch. Open the document document you want to convert, click Add-Ins tab and press the Options button next to Save as Image. From the General list select the output directory and the default file format. After that, expand the Image format list and change the settings for each format. You are allowed to change the resolution (dpi - dots per inch), color and quality. You can configure the resolution only on JPEG, TIFF, BMP, PNG and PCX formats.
