Visual content

The README says it does not inspect some PDF components, including embedded files, multimedia, scripts, forms, internal object names, and digital signatures.github.com · 4 Oct 2026
Compression limit
Because pdfrw does not support all content-stream compression methods, the README recommends decompressing PDFs with qpdf before processing them.github.com · 4 Oct 2026
