About Browser-Based PDF Protection

Browser-based PDF encryption has limitations. This tool strips metadata for privacy and re-saves your PDF in a clean state, but does not apply AES/RC4 encryption to the file. For production-grade password protection, use Adobe Acrobat, LibreOffice, or a server-side solution like qpdf. Your password preferences are recorded as metadata so you can apply them with those tools.
