Hope that helps Just use ImageMagick's convert.
code :
convert foo.pdf foo.png
convert foo.pdf "foo-%03d.png"
gs \
 -q \
 -dNOPAUSE \
 -dBATCH \
 -sDEVICE=pnggray \
 -g2550x3300 \
 -dPDFFitPage \
 -dUseCropBox \
 -sOutputFile=output.png \
  input.pdf
convert \
 -density 300 \
 -define pdf:use-cropbox=true \
  foo.pdf \
  foo.png

it helps some times The stdio API allows you to provide your own replacements for stdin, stdout and stderr, it doesn't affect any activity by the interpreter which doesn't use those.
The pdfwrite device makes extensive use of the filesystem to write temporary files which hold various intermediate portions of the PDF file as it is interpreted, these are then later reassembled into the new PDF file. The temporary files aren't written to stdout or stderr.

it fixes the issue Updated Answer
As an alternative, the following should be faster (as it does the conversions in parallel) and also able to handle larger numbers of files:
code :
find . -name \*.png -print0 | parallel -0 convert {} {.}.pdf
brew install parallel
shopt -s globstar
mogrify -format pdf **/*.png

To fix the issue you can do Do not accidentally specify PDFFitPage in the command line above. Specify EPSFitPage when dealing with EPS files. PDFFitPage will silently do nothing.
Convert PDFs with subset fonts via Imagemagick & Ghostscript

seems to work fine The fact that the fonts are subset is irrelevant. Either the fonts are embedded in the PDF file or they are not. If the fonts are embedded, then it doesn't matter if they are subset, Ghostscript will use those fonts to render the PDF.
If the fonts are not present then a number of different fallback strategies take place, exactly which depends on the nature of the font (TrueType, type 1, CIDFont etc) and the way that GS has been set up.
