Your command produces a 27K PNG image using ImageMagick 6.2.6 and this command:

• convert page-5.jpg -resize 170 -quality 99 -colors 256 -strip page-5.png

For ImageMagick 5.5.7 you can use +profile "*" instead of -strip.

Try -quality 90
The "0" in the ones digit means not to use PNG filtering.
PNG filtering is usually ineffective when there are few (e.g. 256) colors.
