- baicunko 6y agoI'd recommend GS after ImageMagick as IM will hugely increase the size of the output due to rasterization!
- miles 6y agoThe above convert command produced credible output only 6KB larger than the input PDF in my limited testing.
- apetresc 6y agoBut that in itself is a tell.
- miles 6y agoThe whole purpose is to make a new PDF that looks like it was scanned. The file size differing from the original is a feature, not a bug.
- jschwartzi 6y agoAnyone unsophisticated enough to require you to print and handwrite a signature is also unsophisticated enough to not realize that the PDF size is a tell.
- baicunko 6y agoWhen I tested using only IM I was getting 3x file size. I will further test your command to see how this improves the current situation, thanks!!
- derefr 6y agoBut isn't rasterization necessary for this deception to work? Unless there's some magical scanner out there that's outputting vector images.
- eru 6y agoWhether leaving as vector works depends on how much your recipients care to investigate.
