PDFMaxSanitize PDF Online — Free & Private
A PDF can carry more than the page you see — JavaScript that runs on open, hidden metadata with your name and software, embedded files, and other risky elements. Our free Sanitize PDF tool strips all of that out before you share the document. Just upload your file and download a clean copy with the visible content intact. Everything runs right in your browser, so there is nothing to install and no account to create. It works the same on phones, tablets, and desktops, making it easy to clean a PDF safely from anywhere in seconds.
