Thanks for this. Perhaps at in the past I saved a low-importance document with manual jpg compression at 66%, not realising that this would become the default. Yes, exposing the c44 arguments seems like the way forward. They could be left blank by people who want the defaults or used by people who want control.

Thanks for this. I use c44 -slice 12,40,101 $file to match the file size produced by .webp quality 55. A question is, should this be made a default in gscan2pdf? It is hard to answer this without acceptance testing by the majority of users. Could a modifed version for debian be provided for testing? Meanwhile, I wasn't aware that I'd dropped the quality when producing the PDF. Is 66 modifiable when Compression is set to Automatic?

DJVU compression should be better than PDF
