Hi.
I discovered some thing I did not hear before ! An open source free of charge
secure reduction library for PDF !
The secure reduction is highly wanted feature, but unfortunately not available
for Linux as free source. Only in recent versions of Ghost script this feature
implemented BUT FOR VERY LIMITED SCOPE ....
Just several hrs ago, I discover free of charge & open source library for
secure reduction of PDF:
https://itextpdf.com/en
https://itextpdf.com/en/products/itext-7/pdfsweep
& here bellow it's repository on Gitlab:
for java:
https://itextpdf.com/en/products/itext-7/pdfsweep
for .NET (C#):
https://github.com/itext/i7n-pdfsweep
It is the only open source EFFICIENT library. See it, you may take benefit from
it in feature to create "secure eraser" by which user can erase contents of PDF
securely without raster the PDF with subsequent change of text-based PDF into
scanned-like PDF & loss of search & OCR property of original PDF .....
