Hello PDFBox Community,
I hope this message finds you well. I am currently exploring the
capabilities of PDFBox for optimizing PDF files and have a few questions
regarding its compression features:
1. Does PDFBox support standard PDF compression methods, and if so,
what constitutes "normal compression" in this context?
Hmm, maybe you should have a look into the PDF specification.
2. Is it possible to specify a compression range or level, such as
setting compression at 80% or 90%?
There is not ONE compression level for the WHOLE pdf
3. Are all compression-related functionalities available in the
open-source version of PDFBox?
There is no other version than the open source one.
PDFBox supports compressed content streams, compressed object streams
(3.0.x only) and all defined image formats (some requires an additional
plugin).
The PDF spec defines so called filters for every use case to do so. Some
are using lossless others lossy (image data) algorithms . Only the later
provides a compression level.
I would appreciate your guidance on these questions to better understand how
I can utilize PDFBox for my project requirements.
If this is all about reducing the size of a pdf, you have to deal with
the spec to understand the structure of a pdf.

Thank you for your time and support.
Best regards,
