<\/figure>\n\n\n\nHow to add a password to a PDF<\/h2>\n\n\n\n1. Open the tool<\/h3>\n\n\n\n
Go to PDFNeo Protect PDF<\/a>. The page loads immediately \u2014 no sign-up, no account required.<\/p>\n\n\n\n Drag and drop your file onto the page, or click to browse. Any PDF works, regardless of size or page count.<\/p>\n\n\n\n You’ll see two fields:<\/p>\n\n\n\n At least one password is required. For basic protection, just set the User Password.<\/p>\n\n\n\n Hit the button. Processing takes a few seconds. Download the protected PDF \u2014 your original file stays unchanged.<\/p>\n\n\n\n That’s it. The new PDF will ask for a password every time someone tries to open it.<\/p>\n\n\n\n This comes up a lot, so let’s clear it up:<\/p>\n\n\n\n If you just want to stop unauthorized people from reading the file, a User Password is enough. If you also want to prevent copying or printing, add an Owner Password too.<\/p>\n\n\n\n Everything runs locally in your browser. Your PDF never gets uploaded to any server. The password you set is processed on your device \u2014 nobody else can see it. Close the tab and there’s no trace.<\/p>\n\n\n\n Yes. If you know the password, use\u00a0PDFNeo Unlock PDF<\/a>\u00a0to remove it and get a clean, unprotected copy.<\/p>\n\n\n\n Absolutely. You don’t need Adobe Acrobat or any paid software. PDFNeo Protect PDF<\/a> works in any modern browser \u2014 Chrome, Firefox, Safari, Edge. Free, no install, no account.<\/p>\n\n\n\n No. The text, images, layout, and formatting all stay exactly the same. The only difference is that opening the file now requires a password.<\/p>\n\n\n\n There’s no way to recover it. PDF encryption is designed that way on purpose \u2014 if there were a backdoor, it wouldn’t be secure. Keep your passwords somewhere safe, or use PDFNeo Unlock PDF<\/a> while you still remember it to create an unprotected copy.<\/p>\n\n\n\n Ready to protect your PDF?
