About Password Protect app
This application is an ultimate PDF password protection tool that enables you to password protect PDF files online using your browser. You can easily add password protection to PDF files without installing any software in seconds.
PDF (Portable Document Format) contains all the required information about the printed documents, furthermore, you can scroll through the document, search text, fill input fields, add comments, and protect a file from being opened by unauthorized users. Protection is required when we want to secure sensitive or personal information and to make sure that only the person with the password can open and view your file. Of course, PDF security cannot fully protect your file from brute-force password attacks, so it is good to remember to set complex passwords created by password generators. The PDF format supports multiple levels of protection. When protecting the PDF, you can set the Document Open Password (User Password) that will be required to open a file. You can also set the Permissions Password - the password for changing document permissions such as permission for printing, text copying, and editing.
When a PDF document is protected with the Document Open Password, you will be prompted to enter the password to open the file and view its contents. To password protect PDF files using the GroupDocs.PasswordProtect application, upload your file, type the desired password, click the PROTECT button, then download the protected file. The download link will be available for 24 hours, then we automatically remove the files from our servers.
