Scan a folder of incoming PDFs for corruption without changing anything, writing a report:

pdfharmony -verifyonly -o /reports  incoming/*.pdf

Repair and optimize a problem file in one pass — rebuild broken page content and shrink the result:

pdfharmony -rewritepage -optimize -o fixed.pdf  broken.pdf

Convert a batch of files to PDF/A for archiving:

pdfharmony -pdfa -o /archive  *.pdf
