Programming in PostScript - Computerphile
Why Stack Overflow recommends it
Stack Overflow users link it as a quick, citable demonstration that PostScript is Turing-complete, which explains why untrusted PS/EPS files can be a security risk and why PDF and PostScript behave as they do.

What it is
A Computerphile episode in which Professor David Brailsford explains that PostScript is a full, stack-based programming language rather than just a page description format. He walks through how its operators and the stack work, using a PostScript program he wrote himself.

There are a few great videos that explain how recursion and the stack works on the Computerphile channel on youtube. You should watch them all. [LINK] [LINK] [LINK] [LINK] [this video]

PDF uses PostScript, it seems you are having an issue Copy and Pasting from PostScript to 'Summernote', etc. MS Word apparently spent time over the years to play nice with PostScript, there must be info that Word uses to realize it is PostScript and processes the paste correctly. Btw, PostScript is so much more than it would seem. Background info: [LINK] [LINK] [LINK] [this video] Workaround: You could attempt opening the PDFs directly from Word and then Copy and Paste into Summernote. (I have not verified this works) Conclusion: I do not see any way to solve your issue as it all depends on the receiving program, in your case Summernote and others.

Since I landed here while looking for a way to fix convert: not authorized without loosening the security policy for the entire system, I might as well present some improvements to @vaibhav-jain's answer. First, if you're rasterizing EPS to PNG, here's how to skip ImageMagic and go straight to Ghostscript: #!/bin/sh for file in *.eps; do gs -dSAFER -dEPSCrop -r300 -sDEVICE=pngalpha -o "${file%.*}.png" "$file" done -dSAFER puts Ghostscript in a sandboxed mode where Postscript code can only interact with the files you specified on the command line. (Yes, Postscript is turing-complete [this video] .) -dEPSCrop asks Ghostscript to not pad it out to the size of a printable page. ( details [LINK] ) If

For anyone who lands here trying to figure out how to work around ImageMagic's convert: not authorized without reverting the change that was made to the system-wide security policy to close a vulnerability, here's how you'd use Ghostscript to do a batch EPS-to-JPEG conversion directly without bringing ImageMagick into the mix: gs -dSAFER -dEPSCrop -r300 -sDEVICE=jpeg -o outputs-%03d.jpg outputs-*.eps -dSAFER puts Ghostscript in a sandboxed mode where Postscript code can only interact with the files you specified on the command line. (Yes, the parts of EPS, PS, and PDF files that define the page contents are in a turing-complete programming language [this video] .) -dEPSCrop asks for the rendered
