![]() Progressive JPEG images are saved as progressive.Option -optimize is slower, the encoder makes an extra pass over the image in order to select optimal encoder settings.For additional reductions in size try -optimize and -eraseexif options. Resize and rotate are lossy operations.All common picture and graphics formats are supported (i.e. Run imgp -convert (*.png) separately to convert those. XnConvert is a batch image-converter and resizer with a powerful and ease of use experience. PNG files with lower target hres/vres are not converted (even if -convert is used).Doing so may lead to potential race conditions when -overwrite option is used. By default _IMGP files are not processed. Output image names are appended with _IMGP if -overwrite option is not used.If PATH is omitted, the current directory is processed. Multiple files and directories can be specified as source.s byte, -size byte minimum size to process an image r, -recurse process non-symbolic dirs recursively q N, -quality N quality factor (N=1-95, JPEG only) P, -progressive save JPEG images as progressive O, -optimize optimize the output images N, -nearest use nearest neighbour interpolation for PNG ![]() M res, -minres res min resolution in HxV or percentage of -res to resize k, -keep skip (honors -c or -pr) images matching specified f, -force force to exact specified resolution a, -adapt adapt to resolution by orientation o deg, -rotate deg rotate clockwise by angle (in degrees) x res, -res res output resolution in HxV or percentage h, -help show this help message and exit Nautilus Image Converter calls the convert utility from ImageMagick. 4.5GB in size) of mixed resolutions (high to regular) stored in a USB 2.0 external hard disk at an adaptive resolution of 1366×1000 in around 8 minutes.
