Hi, PDF supports incremental saving i.e. only changed objects are stored as an update to the original PDF i.e. they are appended to the end of the original file + Xref infos etc. For details you can look at section 7.5.6 of the ISO 32000 spec. PDFBOX-912 added some basic support for that but AFAIK it doesn't cover all aspects.
