I'm converting this file: https://bureaugravity.com/file/floor.pdf to JPG using the following command: The output I'm getting looks like this: https://bureaugravity.com/file/floor.jpg. I'm getting all these weird gray horizontal lines being introduced. Does anyone know why that might be happening?

My imagemagick and ghostscript are installed on MacOS using Homebrew: imagemagick: stable 7.0.8-22, ghostscript: stable 9.26

This is the full output of convert -version for me:

Do you have Ghostscript installed? If so what is its version? Also what is the version of libjpeg? If not current, then you should try to upgrade those delegates.
works fine for me with IM 7.0.8.23 Q16 Mac OSX using GS 9.26 and JPEG 90.

You can find your version of GS using
You can find your version of libjpeg using
and look at the end of the line for JPG

I am using IM 7.0.8-22 Q16, GS 9.26, and libjpeg 90. Also, I get a perfectly fine result when calling just but I get those weird lines if I use Just calling convert by itself won't work for me because I need the jpg image to be a high resolution.

This command works fine for me with IM 7.0.8.23 Q16 Mac OSX Sierra and GS 9.26 and libjpeg 90. No lines for me
Make sure you have enough space in /tmp. Also try downgrading GS to 9.23. I have heard reports of issue with 9.26 and 9.25. I do not recall about 9.24, but I had good results for a long time with 9.23.

Wow, you were totally right. Downgrading to GS 9.24 completely fixed the issue. Thank you!

You might report this issue to the Ghostscript team.
