I am using the following to convert a PDF to JPEG file:

convert -density 400 test.pdf -scale 2000x1000 hi-res%d.jpeg

However, my creating jpeg file is corrupted, with the following message:

Error interpreting JPEG image (Not a JPEG file: starts with 0x25 0x50)

I have gs version 9.18 installed,

With v7, the usual command is "magick", not "convert".

Does saving to a different format (eg PNG) work? Does reading from a different input (eg PNG) work?

Did you build IM yourself? If so, what version of the jpeg library did you use?
