PNG to eps conversion massive increase in file size

Question

I\'m converting an image from .png to .eps and it hugely increases the file size. Can anyone explain why this is, and how to prevent it increasing so much.

Answer 1

convert indeed blows up the file size because it stores the graphics data uncompressed. A better compression and smaller file size can be achieved by e.g. manually converting using gimp, or by doing

convert image.png image.pdf
pdftops -eps image.pdf

In my case, for example, this results in an eps file with a size of 0.3 MB instead of 5.2 MB (when using convert file.png file.eps directly).
