# Ubuntu – Convert an image from grayscale to binary

convertimage processingimagemagickpdf

I was wondering how to convert an image from grayscale to binary. The image is a one-page document in pdf format.

If I use Imagemagick's convert 1.pdf 1.eps to convert it to eps or other formats such as tif, I find the image becomes blurry. How can I preserve the clarity of the image?

Thanks!
