Use this when an email gateway or a court portal rejects the file for size, and you can trade some image sharpness for that.

Questions
What program actually compresses the file?
Ghostscript’s pdfwrite device, with the /screen, /ebook, or /printer preset. The job is killed if it runs too long or uses too much memory.
Are fonts and vectors rewritten?
Yes. pdfwrite rebuilds the PDF. If you need a byte-for-byte original, do not compress it.
Why is the download the same size?
The compressed result was not smaller, so the download is the smaller input. The note on the result says that.
