Privacy and file handling
PDF processing and previews run in this browser. Document files, names, contents and metadata are not sent to a server or saved in browser storage. There are no ads or third-party scripts in the processing area. Static-site access may still produce server logs.
Your original is unchanged. Output is for printing; link, bookmark, accessibility-tag and signature preservation or secure removal of hidden data is not guaranteed. Even a small scanned file can use substantial memory. Physical-printer and all-browser validation are not claimed.
