I see the same problem with your sample file. It looks like ImageMagick’s delegates for the PDF conversion may have changed with the new install. If you try convert -verbose foo.pdf foo.jpeg, do you see -sDEVICE=pngalpha in the command that gets sent to gs? The pnmraw device has been used in the past, and switching … Read more
you don’t need shell scripting just use the mogrify command cd to your image directory mogrify -format png *.svg
brew remove imagemagick //to delete current version brew install imagemagick –build-from-source fixed it for me on mac
You’re missing the quantity of digits. Use: convert x.pdf x-%04d.jpg Where 4 means 4 digits will be show on the page count.
Try the mogrify command: mogrify -format png *.* But be careful. Without the -format option, mogrify overwrites the original images. Make sure to read the documentation.

Update The mogrify utility that ships with imagemagick can also be used. mogrify -format png *.psd Note: Be careful with mogrify as the docs state… This tool is similiar to convert except … Read more

I don’t have access to your images, so I generated a reference image myself, as … Read more
If you want to keep the original resolution (lossless) you can try the following command: convert png.png -background white -page a4 myoutput.pdf Based on a comment posted before: https://stackoverflow.com/a/24573341/6747994 @m4tx This command only makes sense if the picture has a resolution above 500x800px, it does not zoom in, to avoid pixelated thumbnails.
Note: the solution in this and other answers involves disabling safety measures that are there to fix arbitrary code execution vulnerabilities. See for instance this ghostscript-related and this ubuntu-related announcement. Only go forward with these solutions if the input to convert comes from a trusted source. I use ImageMagick in php (v.7.1) to slice PDF … Read more
Well, I added <policy domain=”coder” rights=”read | write” pattern=”PDF” /> just before </policymap> in /etc/ImageMagick-7/policy.xml and that makes it work again, but not sure about the security implications of that.
